Abraham is among the most classic <a href="https://nameberry.com/">baby names</a> that's still widely-used today, popular for its references to both the Bible and American history. The Biblical Abraham was the first of the Old Testament patriarchs and is considered the founding father of the Jewish people. He was originally named Abram, until, according to Genesis, he was told, "No longer shall your name be Abram, but your name shall be Abraham, for I have made you the father of a multitude of nations."
 In the nineteenth century, President Lincoln hung a beard on the name Abraham, which kept it from reaching the mass modern popularity of other biblical names like Benjamin and Samuel. Interestingly, Lincoln is now a more popular name for boys than Abraham.
 Now that names like Ezekiel and Isaiah are making a comeback, more parents are thinking about a Baby Abie or -- even better -- a Baby Bram. And it does, of course, have the noble namesake of Honest Abe to recommend it. Country music singer Lila McCann chose it for her son, as did musician Ziggy Marley.
 Abraham Van Helsing is the wise Dutch doctor in Dracula who understands the ways of vampires.

Alexander has been in a Top 25 boys' name in the US for 30 years now. But namers are still attracted to its imposing historic pedigree.
 Alexander is derived from the Greek name Aléxandros, composed of the elements aléxein, meaning "to defend," and aner, meaning "man." 
 
According to Greek legend, the first Alexander was Paris, who was given the nickname Alexander by the shepherds whose flocks he defended against robbers. He was followed by Alexander the Great, aka Alexander III, who conquered much of Asia.
 
A royal name in Scotland, Alexander is still highly popular there. In Gaelic, the name became Alasdair; in Spain, Alejandro; and in Italy, Alessandro.
 
The noble Alexander has led to the popularity of many spinoffs, such as Alex, Zander, Xan and Zan, along with female versions such as Alexandra, Alexis, and the unfortunate Alexa.
 Among the many notable Alexanders in history, standouts are Hamilton, Graham Bell, Fleming, Pope and Haig.
 Naomi Watts and Liev Schreiber's Alexander is known as Sasha.

During its Top 10 heyday in the late 90s and early oughts, Andrew was one of the "cooler" classic boy names, an update on the old guard Roberts and Richards.
 While there are still plenty of babies named Andrew -- more than 5000 in the US last year -- it now feels more like a Dad Name than baby name. And the shamed Prince Andrew has not helped the name's image much.
 
Andrew is a variant of the Greek name Andreas, ultimately derived from the element aner, meaning "man." In the New Testament, Andrew was one of the twelve apostles and the first disciple to be called by Jesus. 
 
Although the origins of the name are Greek, Andrew is the patron saint of both Scotland and Russia, as well as Greece. It has associations with two of America's most famous artists, Wyeth and Warhol.
 
One advantage of Andrew is its host of nicknames: Andy makes it friendlier, while Drew adds to its sophistication.
 
Andrew also has several appealing foreign manifestations that are sometimes used in the U.S., including Andre (French), Andrei (Russian), Andres (Spanish), Andrea (Italian), Andreas (German, Dutch and Greek) and Anders (Norwegian and Swedish).

Andrew

Arthur, once the shining head of the Knights of the Round Table, is, after decades of neglect, now being polished up and restored by stylish parents, inspired perhaps by the new generation of royals. Arthur has led the list of possible names for the young British princes, chosen as a middle name for Prince Louis, son of William and Catherine, Prince and Princess of Wales.
 In addition to its leading role in the Arthurian legends, Arthurs figure prominently in Nathaniel Hawthorne's The Scarlet Letter, Edgar Allan Poe's The Narrative of Arthur Gordon Pym of Nantucket and George Eliot's Adam Bede. There are also countless Arthurs in children's literature, movies, and TV -- including The Fonz of Happy Days fame. More recently, Arthur was the son of Mr. and Mrs. Santa in the eponymous movie Arthur Christmas.
 Arthur has many notable namesakes, including playwright Arthur Miller; writer/astronomer Arthur C. Clarke; writers Arthur Conan Doyle, Arthur Rimbaud and Arthur Koestler; philosopher Arthur Schopenhauer; conductor Arthur Fiedler; and tennis great Arthur Ashe, the first African American to win the U.S. Open. Queen Victoria's seventh child was Prince Arthur.
 Arthur was a Top 20 name from at least 1880 through 1926. And in 2011, actress Selma Blair named her son Arthur Saint.

Arthur

Benjamin is a biblical name that has enjoyed widespread favor for decades, ranking in the US Top 50 for almost half a century and the Top 10 from 2015 until 2023. 

One of those golden boys' names that feels traditional as well as sensitive and stylish, Benjamin has the further advantage of the friendly, accessible nickname Ben.
Benjamin is hugely popular not just in the US but in a range of other western countries, including France and Germany along with Scandinavia and Latin America. The names Benjamin and Ben will be familiar around the world.
 Benjamin is derived from the Hebrew name Binyamin, from the elements ben, meaning "son" and yamin, "right hand." In the Old Testament's Book of Genesis, Benjamin was the youngest of the twelve sons of Jacob and Rachel and he was one of the founders of the twelve tribes of Israel. 
 
There have been numerous notable Benjamin namesakes, from Benjamin Franklin to Dr. Benjamin Spock. The name's popularity spiked after the release of The Graduate in 1967, with Dustin Hoffman playing the iconic Benjamin Braddock.
 Benjamin is the name of the sons of Kelly Preston and John Travolta as well as of Gisele Bundchen and Tom Brady.

Benjamin

Most Bills today are dads...or grandpas. The younger Williams are usually nicknamed Will, or called by their full names. 

Bill

Cute kid with freckles, bouncing a Spalding ball. Cool couple Helena Bonham Carter and Tim Burton put the name Billy Burton on their son's birth certificate. While the classic William, name of the future king of England, may in fact be German, the nickname Billy along with such other classic short forms as Jim and Joe are authentically <a href="https://nameberry.com/baby-names/502/english-names-for-boys">English names for boys</a>.

Billy

Charles derives from the Germanic name Karl, meaning "man" or "freeman", and is a royal name in multiple European countries. A famous early bearer is Charlemagne, King of the Franks and Lombards and then Roman Emperor in the 8th-9th centuries. 
 
The word for "king" in several languages, including Slavic, Russian, and Polish, came from Charles. And, of course, Charles III is the current king of Great Britain.
 
Charles is a longtime traditional favorite that was in the Top 10 until the 1960s. Though not as popular as it once was, it's still a widely used name. 
 
The most fashionable form of Charles today is Charlie, used almost equally for girls and boys. And of course, Charlie or Charley is still used as a short form for Charles, along with the old school Chuck and new school Chas/Chaz.
 
Lately, Charles has been resuscitated by many celeb parents, from Jodie Foster to Russell Crowe, honoring a distinguished history dating back to the emperor Charlemagne—the original Charles the Great. 
 
Charles has been so well used for so long that it is virtually faceless—it can conjure up anyone from Dickens to Chaplin to Bronson. It has been an elegant royal name—designating both Bonnie Prince Charlie, leader of a 1745 rebellion, and the present king, as well as previous kings of France, Spain, England, Portugal, and Hungary. 
 
Among the well used international versions of Charles: Carl, Carlo, Carlos, Karel, Xarles, Charlot, and Siarl.

Charles

Cillian is one of the native Irish names that, along with Aiden and Declan, is becoming an unlikely favorite in contemporary America. The Killian spelling has been more popular in the US, but Cillian's star is rising, perhaps thanks to Irish actor Cillian Murphy, star of Oppenheimer and Peaky Blinders.
 There are several Saint Cillians, including one who was sent to Bavaria to convert the natives and was martyred for his trouble. 
 Patrick Woulfe, a Catholic priest who was instrumental in reviving native Irish names in that country after the war for independence from England in the 1920s, theorized that Cillian might also be related to a Gaelic name meaning war.

Cillian

Daniel is one of only a handful of male names that sounds both classic and modern, strong yet approachable, and popular but not cliched. It also has a solid Old Testament pedigree. The only real downside: There are about 10,000 Daniels named each year, making it a less than distinctive choice. 
 
Daniel is derived from the Hebrew name Daniyyel, from the elements din, meaning "judge," and ’el, "God." The Book of Daniel in the Old Testament describes the Jewish prophet’s life of captivity in Babylon and visions of the last days of Earth. 
 Daniel was the name of one of the greatest biblical heroes, with the inspiring story of the prophet whose faith protected him when he was thrown into a den of lions. Yet Daniel does not seem as solemn and weighty a name as other Old Testament names like Abraham and Ezekiel. 

Popular since the days of Daniel Webster and Daniel Boone,
Daniel is a perennial favorite, in the Top 15 <a href="https://nameberry.com/boys-names">names for boys</a> every year since 1972. Daniel ranks first among all <a href="https://nameberry.com/search/boys-names/d">baby names starting with D</a>. 

Daniel's appeal is international, from Ireland to Israel, Finland to Chile. And its nicknames—Danny and Dan—make it sound even friendlier, though, as with other classics, many modern parents are opting to use the name in full.

Daniel

Unlike perennials William, John and James, Edward is a classic that moves in and out of fashion. This royal Anglo-Saxon standard has benefited in recent years from the popularity of the hot hero of the vampire sensation Twilight — Edward Cullen — who has given his name a new infusion of cool.
 
Edward was the name of several Saxon and eight English kings, and is the name of the youngest son of the current queen. It was an early arrival in the New World — there were several Edwards in the Jamestown colony and six on the Mayflower.
 
The Edward name meaning most referenced is "wealthy guardian," as it is derived from elements meaning "rich" and "guard," however, the combined meaning may be a modern interpretation.
 
Youngish actors Edwards Norton, Burns and Furlong help keep the name's image fresh. Parents today are more likely to prefer nicknames Ted or Ned to the traditional Ed or Eddie — or, just as likely, to use the name in full.

Edward

The Christian name of the dashing Mr. Darcy in Pride and Prejudice&mdash; it was his mother's maiden name&mdash; is just one of several Fitz names, including Fitzroy, Fitzgerald, Fitzpatrick, that could be used to honor a dad named William, Roy, Gerald or Patrick.

Fitzwilliam

Iconoclasts though we may be, we like Fred, we like Frank, and we like George, which was among the Top 10 from 1830 to 1950, when the number of little Georges started to decline. Solid, strong, royal and saintly, yet friendly and unpretentious, we think that George is in prime position for a comeback, especially since it was chosen by Britain's royal couple.
 George was the name of the king of Britain for 116 straight years, as well as the patron saint of England (Saint George), who slayed the dragon and became a symbol of good conquering evil. America's most famous George is, of course, Washington, the Father of Our Country.
 Just a few of the many many possible namesakes are George Handel, Shaw, Bush, Gershwin, Burns, Clooney, Shearing, Steinbrenner, Stephanopoulos, Harrison, Orwell, McGovern, Lucas and Clooney.
 Celebrities who have chosen George for their sons include Kristin Scott Thomas, Jane Kaczmarek and Eva Herzigova. George Forman named all five of his sons George.
 Not surprisingly, there are Georges scattered through English and American literature, including in two Jane Austen novels, and in Vanity Fair, Uncle Tom's Cabin and An American Tragedy, not to mention Curious George, "George of the Jungle," George Jetson, George Jefferson, George Bailey and George Costanza.

George

An everyday name in France, a charismatic possibility here.

Henry is back. The classic Henry climbed back onto the Top 10 in the US in 2021 for the first time in over a century, and now stands at Number 7.
 Like James and Theodore, Henry is a traditional name that also manages to feel stylish. Despite its popularity, it's not for everyone, but in some upscale American suburbs, it can seem as if every other little boy is named Henry or Theo or Jack.
 Henry was derived from the French Henri, which ultimately comes from the Germanic name Heimrich, made up of the components heim, meaning "home" or "estate," and rich, meaning "ruler." The most famous bearer is Henry VIII of England, best known for having six wives—two of whom he beheaded for not bearing him sons. It’s been used in the British royal family many times since, including for the current prince better known as Harry.
 
Other illustrious Henrys that might provide baby name inspiration include Henry David Thoreau, Henry (Hank) Aaron, Henry James, Henry Ford and Henry Miller.
 Numerous celebs have chosen Henry for their sons, from Julia Roberts to Minnie Driver to Heidi Klum to Colin Farrell.
 Appealing international versions include Arrigo, Enrico, Enzio and Enrique.

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.
 James, which reentered the Top 5 in 2016, is a current favorite among fashionable parents looking for a baby name that has both style and substance. Like Henry and Theodore, it manages to combine these two stellar qualities.
 
An English derivation of the Hebrew name Jacob, James is biblical (the name of two apostles in the New Testament), royal (kings of both England and Scotland), and presidential (with more U.S. Chief Executives -- six -- than any other name). The name James is also shared by countless great writers and entertainers.
 
There are fewer Jimmys, Jimbos or even Jamies these days; the most fashionable form of the name is James itself. Several stylish celebrities have chosen it in recent years for their sons, including Sarah Jessica Parker and Matthew Broderick, Liz Phair, Colin Farrell and Isaac Hanson. Brendan Fehr thought out of the box and named his daughter James, which has now become a fashionable middle names for baby girls..
James has some interesting foreign variations: Diego and Jaime (Spanish), Jacques (French), Giacomo (Italian), Hamish (Scottish), Jaako (Finnish), Seamus (Irish), Jaap (Dutch) and Jago (Cornish).
 Along with being one of the most popular first names in the US, James is also one of the <a href="https://nameberry.com/blog/top-last-names-in-the-us">most common American last names </a>.

James

John reigned as the most popular of all boys' Christian names for 400 years, from the time the first Crusaders carried it back to Britain until the 1950s. Then American baby namers finally seemed to tire of this straight-arrow, almost anonymous John Doe of names, replacing it with fancier forms like Jonathan and the imported Sean and Ian.
 
John is an English derivative of the Hebrew name Yochanan via the Latin name Iohannes, itself coming from the Greek Ioannes. John was a key name in early Christianity, borne by John the Baptist, John the Apostle and John the Evangelist, plus 84 saints and 23 popes, as well as kings and countless other illustrious notables. Contrary to popular belief, the names John and Jonathan are unrelated, the latter being an elaboration of Nathan.
 
Because many of today's baby Johns get their names for familial rather than stylistic reasons, John isn't as ubiquitous as it once was. For modern parents, the nickname Jack or an international form like Gianni feels much fresher. But John is still one of the Top 10 <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a> of all time.
 
The international versions of John are perennial classics in their own cultures: the French Jean, the Irish Sean, the Scottish Ian, the Welsh Evan and Ewan, the Italian Giovanni, and Gianni the Spanish Juan, the German Johann/Johannes, the Slavic Jan, the Russian Ivan, and on and on.
 
Celebrities who have gone with the timeless John include Michelle Pfeiffer, Bono, Johnny Depp, Lauryn Hill, Bridget Moynahan, and Rob Lowe.
 
Jon may be an abbreviated spelling of John or a short form of Jonathan.

Killian – aka Cillian – is a spirited yet resonant Gaelic name that was borne by several Irish saints and could make a distinctive replacement for the dated Kelly. Kylian is another spelling that's gaining traction, thanks to French soccer star Kylian Mbappé. Possible downsides: an unsavory first syllable and a connection to the trendy brew. 

Killian

Liam is the top boys' name in the US, holding the Number 1 spot for the past five years and also ranking as one of the most popular boys' names around the western world.
 Liam originated as a short form of Uilliam, the Irish variation of William. William is an English name from Germanic roots that was brought to Ireland when the British fled England following the Norman Conquest. The Irish began using English names, including William, which led to the development of Uilliam and its short form, Liam.
 Internationally, Liam is enjoying great popularity not only in the U.S. and its native Ireland, but in countries as diverse as Italy and Israel, Chile and Croatia. If you're looking for a boys' name that will easily translate across many languages and cultures, you can't do better than Liam.
 Irish-born actor Liam Neeson was instrumental in driving Liam up the charts, as was former Oasis member Liam (born William) Gallagher, and, more recently, One Direction member Liam Payne. Celebrities who have chosen Liam for their sons include Tori Spelling, Calista Flockhart, Rod Stewart, Kevin Costner and Craig Ferguson.
 Jaunty and richly textured, Liam holds solidly to the title of most popular boys' name starting with the letter L.

Liam

Matthew was the third most popular boys' name in America throughout the 1980s and '90s, and is still one of the top <a href="https://nameberry.com/search/boys-names/m">boy names starting with M</a>. The New Testament Matthew is the epitome of the fashionable classic—safe and sturdy, yet with a more engaging personality than John or William.
 
Matthew is the English derivative of Matthaios, the Greek form of the Hebrew Mattiyahu, composed of mattan, meaning "gift" and yah, in reference to God. The biblical Matthew was the apostle who wrote the first Gospel in the New Testament. Mateo, Matthias, Teo, Matek, and Mattia are among the many names derived from Matthew.
 Matthew is so common by now, though, that parents have started to seek fresher choices, like Matthew-inspired variations Matthias and Mateo. 
 
The name suddenly became very popular in the U.S. in the 1960s, with Matts appearing on many Western (e.g., Gunsmoke's Marshall Matt Dillon) and other TV shows. Currently there are several prominent real-life Matthews and Matts, including Broderick, McConaughey, Lauer, Damon and Dillon. Celebs who have chosen international versions for their starbabies include Ricky Martin (Matteo), Benjamin Bratt (Matteo), Colin Firth (Mateo) and Will Ferrell (Mattias).

Matthew

Nicholas is derived from the Greek Nikolaos, a name that evolved from the components nikē, meaning "victory", and laos, "people." It shares origins with Nike, the name of the Greek goddess of victory. Nicholas is also a New Testament name that is well-used in literature, such as in Dickens's Nicholas Nickleby.
 
And then there's St. Nicholas who, in addition to bringing bags of toys once a year, is also the patron saint of schoolchildren, mechanics, sailors, scholars, brides, bakers, travelers, and Russia, where the name was a star of the czarist dynasty.
 
Nicholas, though it has lost some ground (it was in the Top 10 from 1993 to 2002), is still a popular classic that would make an attractive, solid choice.
 
Along with this historical depth, Nicholas, and nicknames Nick and Nicky, project an aura of masculine panache, and has long been a favorite of writers for rich boys, Romeos, thugs and detective characters.
 
Offshoots Cole and Colin have long had lives of their own. Short form Nico is hot and getting hotter.

Nicholas

The short, cute Pim is a Top 100 boys' name in The Netherlands though little-known outside that country.  But in a family overrun with Williams, Pim could make an original nickname setting a modern child apart from father Will and grandpa Bill.

A really unusual choice that could be used to honor Grandpa Will. 

Quilliam

Rahaeim

Rahamim

Samuel has been so popular for so long that it's hard to believe it's still climbing, at its highest point since the 1890s. 
 
This biblical name's popularity is somewhat propelled by the likability of the friendly nickname Sam, which returned to favor along with fellow former Grandpa names like Max and Gus. Sam is now often used on its own, for girls as well as boys.
 Samuel is derived from the Hebrew name Shemu’el, meaning "told by God." In the Old Testament, Samuel was one of the great judges and prophets of the Israelites, destined for a holy life from birth. He established the Hebrew monarchy, anointing both Saul and David as kings.
 
High-profile celebs who have chosen Samuel for their sons include Jennifer Garner and Ben Affleck, Jack Black, and Naomi Watts and Liev Schreiber, and Keri Russell and Matthew Rhys.

Samuel

As unlikely as it may seem, Theodore is a hot new hit name, vaulting into the Top 10 in 2021 for the first time ever and rising three more points last year to rank at Number 7.

Friendly nickname Theo may be responsible for some of that, though there are plenty of baby boys given Theo as their full name too. Add their numbers together along with those for Mateo and Teo, and they hands-down become the Number 1 boys' name.

Theodore and Mateo are far from interchangeable names, for sure, and some Theodores are called Teddy....or Theodore. But we predict an overwhelming number of little boys called Theo or Teo on American playgrounds over the coming years.

Theodore is a derivative of the Latin Theodorus, a variation of the Greek name Theodōros. The components are from the Greek words theos, meaning "God," and dōron, meaning "gift," giving Theodore the meaning "God-given" or "gift of God." Names with similar origins include Theodora, Dorothy, and Dorothea.
 
When Theodore Roosevelt took office in 1901, the name Theodore was in the Top 40 <a href="https://nameberry.com/boys-names">boy names</a>, with Teds and Teddys everywhere. After some damaging stereotypes—the chubby Chipmunk Theodore and Beaver Cleaver's real name—Theodore went into a decline, from which it has definitely made a recovery, thanks in part to the popular and likable nickname Theo.
 Theodore has been the choice of several celebrities, including Ivanka Trump, Bryce Dallas Howard, Natascha McElhone, and Ali Larter, not to mention being the fictional son of Christian and Ana in Fifty Shades of Grey.
 The name has a distinguished history. In addition to being presidential, it was borne by novelist Dreiser, poet Roethke, and French painter Gericault, and it was the first name (spelled Theodor) of Dr. Seuss.
 Among the well-known Teds, baseball's Williams and musician Nugent were born Theodore, but Ted Turner was christened Robert, and Ted Kennedy and Ted Danson were originally Edward.
 The beloved character Laurie in Little Women was named Theodore Laurence.

Theodore

A solid classic with plenty of history, Thomas strikes the balance between strength and gentleness. A favorite in the UK, a staple in France, and Australia, and never absent from the US Top 100, Thomas feels like a safe bet and a name that fits into any era. 
The Greek form of the Aramaic name Ta’oma, Thomas means “twin.” It came about in the Bible because there were too many apostles called Judas, and so, Thomas became the “twin”, to reflect his close brotherhood with Jesus. 
Known as “Doubting Thomas” due to his initial skepticism of Jesus’s resurrection, he went on to become a martyr, and there was no need to doubt Thomas’s potential as a given name. 
Brought into common usage by the Normans, it was then always among the 5 most common English names for boys at any point between the 13th and 19th century. 
While it has fallen down the US charts in recent years, it remains a familiar and trusted choice. Given to over 6000 boys every year, it has made a steady climb back into the Top 50. 
Across the pond in the UK, both Thomas and Tommy make the Top 30, while Tom, Tommy-Lee and Tommie have made their mark in the Top 1000. 
As a well-established classic, Thomas naturally comes with plenty of noteworthy namesakes. “Thomas the Tank Engine” might appeal to you kids, but there’s also the theologian, Sir Thomas Aquinas, the cardinal Thomas Wolsey, the Founding Father, Thomas Jefferson. the philosopher, Thomas Hobbes, and the writer, Thomas Hardy. 
More recent namesakes for those who aren’t into history include actors Tom Hardy, Tom Cruise, and Tom Hiddleston, singers Tom Parker and Tom Fletcher, Olympic diver Tom Daley, and Thomas Sanders, of YouTube fame. 
A timeless all-rounder, Thomas comes with the intuitive nicknames, Tommy and Tom, which feel sweet for a child but not too cutesy for a grown-up. For more unexpected options, you could try the nature-inspired Moss or Scottish Tam. 
Unlikely to go out of style anytime soon, Thomas is a refined but approachable choice. If the popularity does give you pause, however, you could try the surname-inspired Thompson, or an <a href=“https://nameberry.com/list/492/100-classic-boys-names--below-the-top-1000/all”> underused classic</a> like Marius, Rufus, or Phinneas. 
Alternatively, there is a wealth of interesting variants to ponder, from Italian Tommaso and Scottish Tavish to Croatian Tomo– and for girls, there’s Thomasina, Tomine and Tamsin.

Thomas

A spelling that would definitely attract a lot of attention -- and a certain amount of confusion as well.

Wellington is a tony-sounding English surname turned baby name by pregnancy guru Rosie Pope, who calls her son Wells for short. It's also the middle name of one of the Sweet Home sextuplets, Blu Wellington.

Wilbur is a stylish name in the UK whose merits are just starting to be discovered in the US. Wilbur, the loveable pig who Charlotte of the Web called Some Pig, is an inspirational hero. And Wilbur and Orville Wright were early aviationists.

Wilbur

Wilfred is one of those Old Man Names that still sounds fusty in the US but is fashionable in the UK. It comes with readymade short forms Will or Fred and might make an adventurous alternative to the ubiquitous William. The central character of Walter Scott's Ivanhoe is the knight Wilfred of Ivanhoe. Wilfred Owens was a well-known British poet.

Wilfred

This dignified German form of William belonged to two German Emperors and Kings of Prussia, as well as a host of other important historical figures. These include composer (Wilhelm) Richard Wagner, philosophers Georg Wilhelm Friedrich Hegel and Friedrich Wilhelm Nietzsche, mathematician Gottfried Wilhelm von Leibniz, and physicist Wilhelm Roentgen, who discovered the X-ray. It now sounds rather dated in Germany, however, having dropped out of the Top 20 there in the late 1920s and continuing to decline since.

Wilhelm

Wilhelmina was long burdened with the Old Dutch cleanser image of thick blond braids and clunky wooden clogs, but that started to be changed somewhat by the dynamic Vanessa Williams character on Ugly Betty, and even further by the choice of Wilhelmina by ace baby namers Natalie and Taylor Hanson. For the less adventurous, Willa is, for now, still a more user-friendly female equivalent of William.
 Wilhelmina was a lot more commonly heard in the U.S. at one time: it was as high as Number 215 in the 1880s, but has been off the list completely since 1955.
 Queen Wilhelmina reigned in the Netherlands for most of the early twentieth century, becoming a heroic figure during the two World Wars. The name got an infusion of glamour via Wilhelmina Cooper, the Dutch-born model who established the top Wilhelmina Model Agency in 1967. Wilhelmina "Willie" Scott was the name of the Kate Capshaw character in Indiana Jones and the Temple of Doom.
 To enliven her image, Wilhelmina has a plethora of nicknames: Mina, Minna, Minnie, Billie, and Willa. Wilma.

Wilhelmina

Will has definitely replaced Bill, not only as a nickname for William but as a stand-alone name as well, partly thanks to England's Prince William, also known as Wills.
 Will has a nice old-fashioned, down-home charm, and with recent references such as Will Smith, Good Will Hunting, and Will and Grace, it has taken on an air of understated cool.
 Most celebrities known as Will were christened William—Shakespeare, legendary humorist Rogers, cartoonist Eisner, and actor Arnett—but others were not. Will Smith was born Willard and Will Ferrell was originally John William.
 A key character on Glee was Will Schuester.

Will

Willa has become increasingly fashionable, with its combination of Willa (born Wilella) Cather-like pioneer strength and the graceful beauty of the willow tree. 
Sophie Turner and Joe Jonas are the latest celebrities to welcome a daughter named Willa. Other stars who used this name include actress Keri Russell, who named her daughter Willa Lou and the late actor Philip Seymour Hoffman, who used Willa for the youngest of his three children. David Mamet and Brian De Palma also have daughters named Willa, plus it's the middle name of Meryl Streep's actress daughter Mary (called Mamie.) Young Willa characters have appears on Six Feet Under and True Blood.
 Willa originated as a short form of Wilhelmina. After a half-century hiatus, it reentered the U.S. Top 1000 in 2010 and soared to the Top 500, for the first time since 1949, in 2015. Willa might also work as an honor name for an ancestral William.

There have been many great Willies (Mays, Nelson, Wonka), but a boy with this name could never ever go to England. Most people will also assume it is short for the more traditional William, which might be the best avenue for achieving this nickname.

Willie

Willoughby is an energetic last-name-first route to the popular short form Will, livelier than any of the two-syllable options. It could be picked up by parents attracted to the Willow sound for girls.
 Willoughby Patterne is the protagonist of the George Meredith novel, The Egotist. Willoughby Sharp was a contemporary artist, curator, critic and founder of the seminal art magazine, Avalanche. There is a classic 1962 British children's novel titled The Wolves of Willoughby Chase by Joan Aiken that was made into a film in 1989.

Willoughby

An ancient tree that figures in literature from Shakespeare to Harry Potter and is believed to possess magical powers, Willow is a lovely name, as graceful as its inspiration.
 Willow's use as a given name derives directly from the willow tree, whose name was derived from the Old English word welig, meaning "willow." Willow trees are associated with grace and elegance, which gave way to the adjective "willowy." Other names with meanings related to willows include Arava, Willoughby, Dozier, Wellesley, Selby, and Salton.
 
This elegant and charming nature name has been chosen for their daughters by Will Smith and Jada Pinkett Smith, Michelle Monaghan and Pink. It's been a fast riser in recent years, climbing along with other Will names Willa, William and Will, having taken off here a year after the character of Willow was introduced on Buffy the Vampire Slayer in 1997.
 
Willow is also popular in other English-speaking countries: Australia and the UK, Canada, Ireland, and Scotland.
 
The name has transcended its one-time hippie aura to move into the realm of reappraised and appreciated <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a>. The willow is believed by the Romani to possess the ability to heal the sick and rejuvenate the aged.
 
Pink was quoted as saying her choice was influenced by a willow tree she grew up near, and that it is the most flexible tree that nothing can break—no wind, no elements, it can bend and withstand anything.

Chef Wolfgang Puck has helped soften this thunderous Germanic name; music-lovers will appreciate its association with Mozart, though the composer's middle name Amadeus is more appealing.
