Aidan was originally a pet form of the Irish name Aodh (pronounced 'ee'), the name of the old Celtic god of the sun and fire. The name was borne by numerous early Irish saints, one of whom was noted for his kindness and generosity. 
 
Aidan is an appealing Irish saint's name meaning fire that zoomed up the popularity lists, jumping four hundred places in a decade to a peak of 39 in 2013 before slumping down. Though it has been overtaken by variant spelling Aiden, the original Aidan is worth considering before selecting one of its offshoots: Caden, Brayden, et al.
 
Aidan was first introduced into the mainstream American consciousness by actor Aidan Quinn, and was given a definite bounce by the appealing Aidan on Sex and the City. Aidan has many variations, among them, Aiden, Aden, Adan, Aedan, and Ayden.

Bennett is Ben with a bow tie, kind of a cross between Benjamin and Beckett. It's been trending up on the popularity charts in recent years, and its choice by The Unbreakable Kimmy Schmidt's Jane Krakowski could shoot it even higher. 
 Bennett Cerf was an eminent publisher--one of the founders of Random House--and renowned punster.
 Bennett is a popular surname, and has many noteworthy bearers, from Jane Austen's Pride and Prejudice family (with one 't') to indomitable singer Tony. Bennett has been used as a surname in England since the early thirteenth century.

Bennett

Caleb is an attractive Old Testament name that has been in the US Top 100 for nearly three decades now. Consistently popular but never too popular, Caleb feels more like a classic than a momentary trend.
 Caleb has two potential derivations, the first being from the Hebrew kelev, meaning "dog," and the second from the Hebrew components kal and lev, together meaning "whole heart." 
 
In the Old Testament Caleb is one of only two ancient Israelites (Joshua was the other) who set out from Egypt to finally enter the promised land. 
 
Caleb Garth is a character in George Eliot's Middlemarch. Caleb was the full name of James Dean's character Cal in East of Eden, and the name has also been heard on Desperate Housewives and Buffy the Vampire Slayer.Julianne Moore chose Caleb for her son, as did Bo Bice. The shortform Cale is also rising in popularity, and the current Kaleb spelling picks up on the K-to-C initial trend.

Caleb

Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal. Kyle MacLachlan chose Callum for his son. Callum might also be spelled Calum; in Ireland, the name became Colm, and in Scotland it's sometimes used as a pet form of Malcolm.
 
Callum was derived from Latin Columba, a unisex given name meaning "dove." Callum was popular among early Christians because the dove was a symbol of purity, peace and the Holy Spirit. St. Columba was one of the most influential of the early Celtic saints.

Callum

Cole -- a short name that embodies a lot of richness and depth -- has long been associated with the great songwriter Cole Porter. It's quite popular in Scotland.
 Old King Cole -- which refers to a real British king -- is familiar to all kids. Cole was the name of the child in The Sixth Sense and was also the name of -- sorry -- the notorious outlaw Cole Younger, who was born Thomas Coleman.

Cole

David is an enduring worldwide classic, used from ancient times to the present day.
 David is derived from the Hebrew name Dawid, believed to come from the root dôwd, meaning “beloved”. The first famous David was the Old Testament second king of Israel: the shepherd boy who killed the giant Goliath, and later a warrior, poet, and powerful leader, wise but humanly fallible. He is an important figure in Judaism, Islam and Christianity, and later inspired many works of art, including Michelangelo’s colossal sculpture.
 Since then, there have been countless Davids of note in history, literature, and popular culture, including the patron saint of Wales — a translation of the Welsh name Dewi — two kings of Scotland. Then there’s Copperfield, Crockett, Bowie, Beckham, Letterman, Grohl, and many more. Celebrities who have chosen it for their sons include Jennifer Hudson, Bar Refaeli, and J.K. Rowling.
 In its international forms, David is steadily popular around the world, and ranks in the Top 10 names in Brazil, Austria, Armenia, Croatia, Bosnia and Herzegovina, and Israel.
 In the USA, David has never been out of the Top 40 boy names, but was at peak popularity in the mid-twentieth century, ranking in the Top 10 from 1936-1992. This means that, although it’s still given to thousands of boys each year, it has an “older man” feel to it. It ranks highest in states with a large Jewish population, and is still a Top 10 name in New York.
 After Daniel, David is the second most popular <a href="https://nameberry.com/search/boys-names/d">boy name starting with D</a>. Although fading a little in popularity, it remains a serious-yet-friendly classic with deep roots.
 If you’re looking to update David, perhaps as an honor name, the freshest alternatives are surnames deriving from David, including Dawes, Dawson, and Davies. You could also try an international variation, like Welsh Dai or Finnish Taavi.

Duncan is jaunty, confident, and open, a Scottish <a href="https://nameberry.com/list/453/royal-baby-names">royal name</a> that's brimming with friendly charm and makes it into our golden circle of names that are neither too popular nor too strange. Popularity aside, Duncan is one of the most classic <a href="https://nameberry.com/list/473/scottish-names-for-boys">Scottish names for boys</a>. 
 From a surname based on a clan name, Duncan was the name of a Scottish saint and two early Kings of the Scots. The beneficent Duncan I, who lived in the eleventh century, was immortalized in Shakespeare's Macbeth. 
 The brave and handsome Major Duncan Heyward is one of the main characters in James Fenimore Cooper's The Last of the Mohicans. Other cultural references include Duncan Idaho, the only character to appear in all of Frank Herbert's Dune novels; Duncan MacLeod, the immortal protagonist of Highlander; one of Garp's sons in The World According to Garp; and singer-songwriter Duncan Sheik.
 David Bowie's son Zowie changed his name first to Joey and then finally to Duncan.
 
Duncan peaked int he late 90s and has been a downfall since, even falling out of the Top 1000 in 2021 — but made a reappearance in 2022.

Duncan

Strong, charismatic, and sleek, Elias has followed in the footsteps of Elijah and Eli to become a popular choice among parents today. 
While it may sound cool and fresh, Elias is a name with history and substance. It is the Greek form of the name Elijah, meaning “Yahweh is God,” and was used in both the Greek New Testament and medieval tales. Elias was then given to early saints, to honor the miracles and work of the popular Biblical figure. 
Revived by Puritans in the 18th century, notable namesakes include the inventor of the sewing machine, Elias Howe, writer Elias Canetti and Walter Elias Disney. 
Felix Mendelssohn composed a popular oratorio named “Elias”, while Sir Walter Scott, Anthony Trollope, and Thomas Hardy all have characters called Elias in their novels, giving the name literary and classical charm. 
In the US, Elias has seen significant usage from the 90’s onwards with its popularity doubling during the 2010’s. Given to over 6000 boys each year, Elias continues to climb the charts and has overtaken Eli as a go to El- choice. 
While still outranked by Elijah in the US, across Europe and South America, Elias is the preferred form. Popular in Sweden, Germany, Switzerland, Uruguay, and Mexico, Elias travels well. 
The name has been chosen for characters in the popular horror podcast, The Magnus Archives, Cassandra Clare’s trilogy “The Infernal Devices”, and the TV series “Person of Interest.” Elias has the celebrity seal of approval too, with singer Michael Bublé, actor Robert Downey Jr, tennis player Boris Becker and actress Barbara Becker choosing to use it for their sons. 
Handsome and refined as it is, the main problem with Elias is deciding whether you want to use it, or keep Elijah, Eli, Elliot, Elio, Eliza, Elizabeth, or Elise in the running. To avoid the problem, you could go with similar but lower ranking Tobias, Linus, or Ozias.

Elias

Ezra has a lot going for it: the strength of its heroic Biblical legacy, its quirky sound, and its fresh but familiar feel. Ezra is now at its highest point ever, but its intuitive streamlined spelling and deep roots could make it a worth successor to Elijah in the Top 10 -- or even to Liam or Noah at Number 1.
 Ezra just misses being among the elite group of male names that's always been in the US Top 1000, having dipped below the cutoff in 1964 and '67. Ezra also makes the Top 100 for boys in other English-speaking countries along with the Netherlands.
 Ezra is an abbreviation for the Hebrew phrase Azaryahu, meaning "Yah helps". In the bible, Ezra led a group of fifteen hundred Israelites out of slavery in Babylon and back to Jerusalem. 
 
Other notable Ezras include poet Ezra Pound and New York Times political columnist Ezra Klein. Ezra Cornell was a founder of Western Union and co-founder of the university that bears his name and Ezra Jack Keats is a popular children's book author-illustrator. 
 Both Paul Reiser and Taylor Hanson are dads to boys named Ezra, and there are Ezras to be found in Wilkie Collins's The Moonstone and Daniel Deronda by George Eliot.
 And let's not forget the band—Better Than Ezra—along with rising actor Ezra Miller, Vampire Weekend musician Ezra Koenig or the character Ezra Fitz from Pretty Little Liars.
 As unlikely as it may seem, Ezra is also growing in popularity as a girls' name, making the girls' Top 1000 in 2018 ad still rising. About 450 baby girls were named Ezra last year, but about 8000 baby boys, which puts Ezra below our 10% minimum to be considered a unisex name.

Ezra

Well used in England and Scotland since the fifties, the smooth and sophisticated Graham is catching on here.
 Among the best known bearers are novelist Graham Greene, racing driver Graham Hill and painter Graham Sutherland, as well as musicians Graham Nash and Parker--and Gram Parsons.
 Though long associated with the Scots, Graham actually developed as a surname in England, dating back to the eleventh century. In the UK, it is sometimes spelled Graeme.

Graham

Hudson has risen quickly up the charts over the past 30 years, getting a lot of its style value from New York's Hudson River. That makes it a nature name and a place name that's also got the fashion gloss of New York City.
 The Hudson River was named for 17th century British explorer Henry Hudson, who also gave him name to Canada's Hudson Bay. Hudson has long been a prominent surname. Along with Henry, there was also heartthrob Rock, director Hugh, the musical Hudson brothers, and Kate Hudson today. 
 As a first name, Hudson has been given to several celebrity children, including the sons of Marcia Gay Hardin, Gena Lee Nolan, and Drew Lachey.
 Hudson literally means 'son of Hudd', which was a nickname for both Hugh and Richard in the Middle Ages. Streamlined spelling Hud was the name of the macho title character of an iconic Paul Newman film; John Mellencamp has a son named Hud.
 James Barbour pulled a gender switch when he named his daughter Hudson in 2008.
 Along with its popularity in the US, Hudson also ranks in the Top 100 in other English-speaking countries. Its popularity has not, however, extended to other European countries, many of which have laws against using surnames as first names.

Hudson

Jude is a modern star, maintaining a steady level of popularity -- but not TOO much popularity -- for more than a decade now. Thank Jude Law and the great Lennon-McCartney song "Hey Jude", double-handedly responsible for propelling Jude up the charts.
 Saint Jude was the apostle who interceded for people with problems and became the patron saint of lost causes.Kelsey Grammer has a son named Jude Gordon. Jude is occasionally used for girls (as in Martha Stewart's granddaughter)--but more often as a shortened form of Judith/Judy.
 Jude's old connections to the traitorous Judas Iscariot and Thomas Hardy's tragic Jude the Obscure have mostly faded from memory, though don't be shocked if Grandma objects to the name on these grounds.

Jude

This attractively energetic Italian version of the classic Matthew is primed to move further and further into mainstream American nomenclature. Mateo is technically the Spanish version, but many parents in the US use the two spellings interchangeably. 
 
In the US, about 12,000 baby boys were named Mateo, Matteo, or Teo in 2021, vaulting the name in all versions into the Top 10. Mateo alone, by far the most popular version, lies just outside the Top 10.
 Actor Colin Firth has a son called Matteo, as does Ricky Martin; the Benjamin Bratts and Tom Colicchios have boys named Mateo. We're sure that both these spellings will keep climbing in tandem, sharing the possibility of the lively nickname Teo.

Matteo

A happy medium between the weighty Maximilian and the laid-back Max, Maxwell is one of the most classic and attractive <a href="https://nameberry.com/list/428/scottish-baby-names">Scottish names</a>. Early influences on the name's revival include Maxwell Smart of the television show, and then movie, Get Smart, and the Beatles song about Maxwell's Silver Hammer.
 Lance Armstrong chose it for his son, but there was a sharp and unexpected gender switch when both Jessica Simpson and Lindsay Sloane both chose it for their daughters. Still, in the US baby boy Maxwells outnumber baby girls 50 to 1.

Maxwell

Oliver is an international star, ranking near the top of the charts in the US and throughout the English-speaking world, along with a host of European and Latin American countries, from Norway to Chile, Slovenia to Switzerland.
 
Long a popular choice in England, Australia and New Zealand, Oliver entered the list of Top 100 <a href="https://nameberry.com/boys-names">baby boy names</a> in the U.S. for the first time in 2009, but has already jumped to the top of the charts. Why? Because Oliver is energetic and good-natured, stylish but classic, with a meaning symbolizing peace and fruitfulness. 
 
Oliver derives from Olivier, the Norman French variation of the Ancient Germanic name Alfihar ("elf army") or the Old Norse Áleifr ("ancestor's relic"), from which comes Olaf. Olivier emerged as the dominant spelling for its associations with the Latin word oliva, meaning "olive tree."

Oliver was used as a given name in medieval England after the spread of the French epic poem ‘La Chanson de Roland,’ which features a character named Olivier. It lost favor after the seventeenth century rule of Oliver Cromwell, then was revived in the nineteenth century. 

Oliver's biggest boost in this country came from the hit book and movie Love Story, which also catapulted the name Jennifer to stardom. Notable namesakes range from Oliver Wendell Holmes to Oliver Hardy to Oliver Stone. In fiction, there is Oliver Twist, and Oliver is also a Harry Potter name.
 Oliver works particularly well with single-syllable surnames, as in Oliver Stone, North and Puck (son of Wolfgang). Other celebrities who have chosen Oliver include Bridget Fonda, Fred Savage, Stephen Stills, and Taylor Hawkes. 
 International forms include the French Olivier, the Spanish Olivero, and the Italian Oliviero.
 Parents considering Oliver for their sons might consider that with Olivia at the top of the charts for girls, there will be an awful lot of children with names starting with Oliv-.

Oliver

Peter is derived from the Greek Petros, meaning "rock" or "stone." One of the most important figures in the Christian hagiography is Saint Peter, keeper of the Gates of Heaven. Born Simon bar Jonah, he was given the nickname Peter by Jesus, to signify that he would be the rock on which Christ would build Christianity. Centuries later, there was Peter the Great, the czar who developed Russia as a major European power.
 
For generations, there have been pleasant childhood associations with this classic New Testament name, what with Peter Rabbit, Peter Pan, et al. But as user-friendly as this makes the name, it has a solid, traditional side as well.
 
Never as widely used as some of the more traditional Anglo-Saxon stalwarts, Peter retains an enduring appeal to parents seeking a less-used classic, with those nice childhood associations. Peter also has some interesting derivatives: The Brits like Piers; the Irish, Pierce and Pearse; the Italians, Piero and Pietro; the Spanish, Pedro; the French, Pierre; and the Dutch, Piet.
 
One potential problem: in some parts of the world, "peter" can be a slang term for "penis".

Peter

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

Sebastian is an ancient martyr's name turned literary, and Little Mermaid hero—think Sebastian the Crab—that's more popular than ever, as a classic-yet-unconventional compatriot for fellow British favorites T Theodore and Oliver.
 Sebastian is derived from the Greek Sebastianos, meaning "from Sebastia." Sebastia was a city in Asia Minor—modern day Sivas, Turkey. Sebastian is a name with a substantial history, first as the third-century martyr whose sufferings were a favorite subject of medieval artists, then as the name of memorable characters in such varied works as Shakespeare's Twelfth Night and The Tempest and Evelyn Waugh's Brideshead Revisited.
 Sebastian is high on the lists in countries as widespread as Austria, Denmark, Romania, Australia and Chile. Some more down-to-earth nicknames for the relatively elaborate Sebastian not often heard in this country are Seb, Baz and Bas. 
Several celebs have chosen the sophisticated Sebastian for their sons, including James Spader, Kim Fields, Malin Akerman and Tommy Hilfiger.

Sebastian

Simon is pure and simple (not in the nursery rhyme sense), and an appealingly genuine Old and New Testament name that's not overused – making Simon a stylish choice. In the Bible, Simon was the second son of Jacob and Leah and the original name of Saint Peter, as well as the name of several New Testament figures. Historically, Simon Bolivar is known as The Liberator of Latin America.
 

The New Testament spelling of Simon (rather than Simeon) was probably influenced by the unrelated Greek name Simon, meaning "flat-nosed". The Hebrew Shim'on or Simeon means "He has heard". Later, it was also conflated with the Old English name Sigemund ("victory-protection") — so there's an element of several origins and meanings in the name.

 Simon was one of the more appealing characters in Lord of the Flies, then became part of the British invasion of names that hit U.S. shores along with the Beatles. Other recent notable Simons include Simon Templar, aka The Saint; Simon Cowell, snarky judge on The X Factor; Simon Le Bon, lead singer of Duran Duran; and Simon Baker, Australian-born star of The Mentalist. 

 Simon is currently very popular in several European countries, including Austria, Denmark, France, Sweden, Switzerland and Belgium.

Simon

Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.
 As a family surname, Spencer became the middle name of Winston Churchill, and was the maiden name of Princess Diana. The surname version was often spelled Spenser in the past, as in Edmund Spenser, the poet known for The Faerie Queene.
 The protagonist of Henry James's short story The Jolly Corner" is Spencer Brydon.

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.
