Rarely used, and for good reason. Alonzo is a preferable choice.
 Alphonse does have a mixed bag of notable namesakes—French novelist Alphonse Daudet, painter Alphonse Mucha, and it was the birth name of gangster Al Capone.

Alphonse

Alvin has a sturdy, no-frills sound that belies its somewhat whimsical meaning. Interesting potential namesakes include British rocker Alvin Stardust, and US footballer Alvin Williams, and African-American dance legend (and activist) Alvin Ailey.

Alvin

Ash has Southern charm plus the arboreal-nature appeal. Plus your little boy will prize Ash as the name of the hero of the Pokemon cartoons. Ash can also be a dashing short form of Asher, Ashton, or any other "Ash" name.

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 since 2015. 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

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>.

Brandon, a forebear of the Braden-Caden pack, had a great run of popularity over several decades, being in the Top 10 from 1992 to 1998, one of its inspirations being hearthrob Brandon Walsh played by Jason Priestley on the original Beverly Hills 90210--and it was aso the name of several soap opera characters. 
 Newer names like Landon and Braden are feeling fresher to many parents, and it's sometimes confused with the Irish Brendan.

Brandon

Bruce is a Norman place name made famous by the Scottish king Robert the Bruce, who won Scotland's independence from England in the fourteenth century. It's perennially popular in Scotland, but has been rarely used here for a generation -- though the impact of Bruces Lee, Springsteen, Dern and Willis, as well as Batman's Bruce Wayne -- still lingers. At one time Bruce was so widespread in Australia, it became a nickname for any Ozzie man. An interesting alternative is Brix, the Normandy place name where the Bruce family originated.

Bruce

Chase, with its sleek and ultraprosperous aura, is redolent of the worlds of high finance and international banking. Chase has been well used during the last few decades, seen as a character on 24 and on several young-audience shows. 
 There are a disproportionate number of football stars name Chase.

Chase

The Darien spelling, which relates to the posh Connecticut town, peaked at Number 393 in 1994 but more recently has been just hanging on at the bottom of the Top 1000.  Still, a name with an appealing sound and feel that may ascend again.

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.

David

The jazzy, ultra-cool Dexter, like most names with an "x," has a lot of energy and dynamism. Over the years, it's been attached to a number of diverse real and fictional personalities—C. K. Dexter Haven, the witty Cary Grant character in The Philadelphia Story; Dexter Green, the protagonist of the F. Scott Fitzgerald story "Winter Dreams"; great jazz tenor saxophonist Dexter Gordon; the boy-genius protagonist of cartoon Dexter's Laboratory; and the most recent TV series Dexter based on the books by Jeff Lindsay, whose lead happens to be a genial but sociopathic serial killer.
 Dexter was chosen by hip musical couple Diana Krall and Elvis Costello for one of their twin boys, and by singer Charlotte Church.
 Dex is an equally appealing nickname, now sometimes used on its own.

Dexter

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

A stalwart of Latin nomenclature that could work just as well for Anglos. Proof lies with the celebrity birth announcement — Hilaria and Alec Baldwin named their fifth child Eduardo Pau Lucas in 2020. This doesn't seem to have much impact on other parents, though: over 900 boys received the name in 2021, but the number is steadily decreasing.

Eduardo

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

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity. 
 Finn was chosen by cool couple Christy Turlington and Ed Burns for their son, and also by Jane Leeves and Autumn Reeser. Played by Cory Monteith prior to his death, Finn Hudson was a prominent character on Glee.
Other up-and-comers in the same family: Finlay and Finley, Finian and Finnian, Finnegan and Finnigan, and, from Germany, Fynn.

Finn

Despite the presidential pedigree, it's still hard to shake the image of the cartoon cat (named after his creator Jim Davis's grandfather). However, there are other Garfields, such as Barbadian cricket player Sir Garfield Sobers, who carries it with gravitas.

Garfield

Previously used primarily by Latino families, this name of the great hero of the Trojan War as related in Homer's Iliad is beginning to be considered more seriously by others seeking noble ancient hero names as well--it was also the name of the knight who raised King Arthur as his own son.
 In addition to being used for many contemporary Hispanic movie and TV characters,
other Hectors appeared in such films as Mystic Pizza and Lars and the Real Girl. In literature, you can find Hectors in Thackeray's Vanity Fair and Balzac's Cousin Bette.
 Some notable real-life Hectors: composer Berlioz and actor Elizando.

Jack may have fallen from its Number 1 place in England, but in the US it's as popular as it was at its height in the 1920s and 1930s. A durable, cheery, everyman form of John, Jack ranks as one of the most popular <a href="https://nameberry.com/search/boys-names/j">boy names starting with J</a>. 
Jack is a derivative of John that originated in medieval England. The name went from John to Johnkin to Jankin to Jackin to Jack. The name was so common in the Middle Ages that Jack became a generic term for a man. 
 
Jack is familiar to all from earliest childhood via Jack and Jill, Jack Sprat, Jack and the Beanstalk and Little Jack Horner et al. It is still a recent favorite for novel, TV and movie characters. 
 
Jack is at the top of the charts in Ireland and Scotland, and also ranks highly in Germany, Sweden, the Netherlands, and Belgium.
 
The jaunty Scottish version is Jock.

Jack

This unpretentious, accessible, and optimistic ("everything's jake" -- meaning OK) short form of the top name Jacob is itself widely used, though more parents these days are opting for the full name Jacob. Jake (born Jacob) Gyllenhall is its most prominent current bearer. 

Jake

Jonathan was derived from the Hebrew name Yehonatan, eventually contracted to the modern Yonatan, meaning "gift of Jehovah." It comes from the elements yeho, in reference to God, and natan, meaning "to give." In the Old Testament, Jonathan was the valiant eldest son of King Saul, and it was his friendship with brother-in-law David that gave rise to the expression "Jonathan and David" to describe devoted, steadfast friends.
 
Jonathan is the biblical name that started to replace the stalwart John in the late fifties, sounding more playful, sensitive and modern. Now, after being high on the list for several decades, Jonathan has pretty much lost its luster.
 
Anne Hathaway named her oldest son Jonathan Rosebanks in 2016.
 
Jonathan has spawned numerous spelling variations, including Johnathan, Jonathon, and Jonothan.

Jonathan

Kevin was derived from the name Caoimhín, which originated from the Irish elements coém, meaning "handsome," and gein, "birth." The feminine name Caiomhe, anglicized as Keeva, comes from the same origins. Kevin was first popularized by the seventh century Saint Kevin, who founded a scholastic monastery near Dublin and was rewarded by being made one of that city's patron saints.
 
Kevin has been waning in popularity in recent years—it dropped out of the Top 100 for the first time since the Truman administration in 2017—and definitely seems more a dad's name than a baby's name these days. (Think Kevin Bacon, Kevin Costner, Kevin James).
 
In America, the Irish Kevin has had an impressive forty-plus years of popularity. However, in Germany, Kevin has become the poster child for names associated with lower social classes—essentially, names that feel very American. Kevinism has become slang for fleeting name phenomena, typically associated with pop culture trends. Kevin was the top boys’ name in France in the early 1990s—one of the first non-French names to hold the title.

Kevin

In Ireland and Scotland, Mac and Mc mean "son of"; here, Mac is a generic fella, or a short form cooler than either Matt or Max. Mac can be a nickname of any longer Mac or Mc starting name such as McCoy or Macalister. If you want to make it feel more complete, you can always spell it Mack.

Mitchell has had something of a roller coaster ride, showing some panache in the forties and fifties, when it was seen as a sharper alternative to Michael with its cool Mitch nickname, slipping a bit, then resurfacing in the 90s when it reached as high as Number 71. Mitchell Pritchett is one of the leading characters on the TV sitcom Modern Family.
 Mitchell is an English/Scottish surname name, derived from a medieval nickname of Michael.

Mitchell

Mordecai, although it has a noble heritage, has never caught on in this country, because of its rather weighty image. 
 Mordecai is a symbolic name for boys born on the holiday of Purim, because this cousin of Queen Esther helped her save the Jews from destruction at the hands of Haman.
 Mordecai Richler was a Canadian author and screenwriter whose best known work is The Apprenticeship of Duddy Kravitz.

Mordecai

A name that Yanks might see as overly British, but combined with the right surname, it does have a measure of Sherlock Holmesian dash via Nigel Bruce, who played the original Dr. Watson to Basil Rathbone's Sherlock Holmes. 

Nigel

Ralph has two diametrically different images: there's the suave Ralph Fiennes-type Brit (often pronounced Rafe), and then there's the Jackie Gleason blue-collar, bowling blowhard Ralph Kramden bus driver. It's all in the eye of the beholder, though its hip factor did rise when it was chosen for his son by cool U.K. actor Matthew Macfadyen.
 Ralph is a name that's been around for a thousand years, was in the Top 30 from the 1870s to the 1920s, and just could make a comeback.
 Ralph has a number of notable namesakes, from Ralph Waldo Emerson to Ralph Abernathy to Ralph Lauren. In literature, Ralph is a Shakespearean name, appearing in Henry IV, is a pivotal figure in Henry James's The Portrait of a Lady and Ralph was one of the three main boys in Lord of the Flies. And let's not forget Ralphie in A Christmas Story.
 Or you might prefer the French version--Raoul.

Ralph

Raphael is a romantic archangel name that sounds both artistic and powerful. Raphael is also a great cross-cultural choice, with significance for people with both Latinate and Jewish roots, plus plenty of grounding in the English-speaking world.
 Raphael was one of the seven archangels (called by Milton "the affable archangel") who attended the throne of God and, as the angel of healing, is the patron of doctors as well as of travelers, science and healing. Another worthy namesake is the great Renaissance painter Raphael (born Raffaello Sanzio). Several celebs have chosen the name, including Robert De Niro, Ana Ortiz and Melissa George.
Rafael is the Spanish spelling, as represented by Spanish tennis champ Rafael Nadal. Rafi is the familiar Hebrew nickname.

Raphael

Now that it's no longer fashionable for girls, Robin is rising for boys again. Robin Hood, Robin Williams, Christopher Robin, and Robin the Boy Wonder are all male namesakes, after all. It reentered the US Top 1000 <a href="https://nameberry.com/boys-names">boys names</a> in 2015 for the first time since 1999 and continues to bounce around the lower end of the Top 1000.

Robin is one of the unisex names that switched predominant genders a couple of times. Initially a boys' name, it hit its high point for both genders in the 1950s, eventually becoming more popular for girls. Now Robin is used near-equally for both sexes, given to 290 baby girls and 256 baby boys in the US in 2021.

Robin is one of the <a href="https://nameberry.com/popular-names/france">Top 100 Boy Names in France</a>.

Robin

We've seen Ray regain his cool, but could this country/cowboy name epitomized by Roy Rogers (born Leonard Slye), Acuff, and Clark, do the same?
Roy came into use in the late nineteenth century, probably influenced by the main character of Sir Walter Scott's novel Rob Roy, in which the historical character Robert M'ac Gregor is nicknamed Roy for his red hair.
There have been lots of notable non-country namesakes, including baseball's Roy Campanella, humorist Roy Blunt, Jr., Walt's brother and partner Roy Disney, singer Roy Orbison and pop artist Roy Lichtenstein. Roy Hobbs was the protagonist of the Malamud novel The Natural, played in the film by Robert Redford.
 Roy was also the first name of clothing designer Halston.

Sky is an ambigender nature name that was first legitimized as the character of Sky Masterson in the 1950 musical Guys and Dolls, played in the film version by Marlon Brando. It's a name we appreciate for its clear, wide-open feel, less hippyish than others like Rainbow and Starlight, and makes an appealing middle name possibility.
 Sky is the name of Sophie's fiance in Mamma Mia, and there are both Power Rangers and Transformers with the name. Elizabeth Berkley used it for her son.
 It is also spelled Skye, as in the island in the Inner Hebrides of Scotland. Plus, it's a logical nickname for the variously spelled Schuylers and Skylers.

Steven, the phonetic and now predominant spelling of the classier Stephen, has finally dropped out of the Top 100 after seventy years.  Steve has become one of the ultimate regular-guy names, right up there with Dave and Joe. and there have been  innumerable pop-culture role models among its bearers--from Steven Spielberg to Steven Soderbergh to Steve Jobs.

Steven

Thaddeus, a distinguished, long-neglected name, has several areas of appeal: a solid New Testament legacy, a nice antique feel, and the choice of several more modern nicknames and international variations.
 In the Bible, Thaddeus was one of the original Twelve Apostles.
 Thaddeus has made quite a few screen appearances, ranging from Spongebob Squarepants to Police Academy to Get Smart (it was the given name of the Chief) to Harry Potter. As Tadzio—the Slavic version—he played a leading role in Thomas Mann's Death in Venice.
 In real life, Thaddeus Stevens was a dominant political figure during the Civil War. Mia Farrow has a son named Thaddeus.

Thaddeus

Also related to the word for wolf, this name has a first syllable that's not appealing to the American ear. Better ic-ending choices: Dominic, Frederic, Eric. 

Ulric

A Leave It to Beaver/old comic-strip name, vacationing for years with the Griswolds in WallyWorld, but now back as WALL-E?

William is one of the most enduring of classic names for boys. It's also among the most popular boys' names, as American parents see it as being ideally conservative yet contemporary, and hands-down the most popular <a href="https://nameberry.com/search/boys-names/w">baby name beginning with W</a> of all time. 
 For 400 years, William has been second only to John as the most popular name in the English-speaking world. And now of course, it's also a newsy name—thanks to Britain's high-profile Prince William.
 William is derived from the Germanic name Wilhelm, composed of the elements wil, "will," and helm, referring to a helmet or protection. The name was introduced to England by William the Conqueror, with William being the Norman variation of the name. In Central and Southern France, it was translated as Guillaume.
 
In terms of short forms, yesterday's Bills and Billys have given way to today's Wills—or Williams, with no diminutive—though a few hip Billys, including Helena Bonham Carter and Tim Burton's, have surfaced recently. 
 But Irish spinoff Liam is the most stylish William nickname and has now superseded William, becoming the most popular boy name in America. Riding the William bandwagon is the Dutch Willem, which comes with the unique nickname Pim.
 
William has long reigned as a royal name in the U.K. There are tons of worthy namesakes called William, including William Shakespeare, Bill Gates and four U.S. presidents.

William

Wyatt has been hot, which is to say cool, for several years now. With its easy Wyatt Earpish cowboy charm, it's relaxed but still highly respectable. 
 Wyatt is a lot more classic a name than you might guess. It's one of those names that just misses ranking in the Top 1000 for its entire 140+ year history.
 
Wyatt was derived from the Medieval English name Wyot, itself a form of the given name Wigheard, with wig meaning "war" and heard, "brave." Wyot, along with variations Wiot and Gyot, were also used by the Normans as nicknames for names such as William. Wyatt became a patronymic surname later in the Middle Ages.
 
Wyatt got one of it first modern pushes when Peter Fonda played a Wyatt in the seminal film "Easy Rider. Goldie Hawn and Kurt Russell were among the first celebs to use Wyatt for their son born in 1986; more recently, singer Sheryl Crow chose it for her baby boy. Wyatt is also the name of the alter ego of a central character on the HBO show Westworld.
 
And even more recently, Mila Kunis and Ashton Kutcher used the name for their baby daughter, perhaps pushing the name across the gender line, though it has a long way to go before it's considered unisex; it's still much more popular for boys than it is for girls. Does the baby name world have Wyette in its future?
 
Wyatt is also enjoying a wave of current popularity in Canada.
