The origins of the name Brian are not entirely clear, but it is suspected that it evolved from an Old Celtic word related to nobility. In Ireland the name is associated with Brian Boru, the most famous of all Irish warrior-kings, credited with driving the Vikings out of Ireland around the year 1000. 
 
Like other native Irish names, Brian was outlawed in Ireland during the centuries of British rule, restored to use after the war for Irish independence in 1916. Irish immigrants propelled it onto the US Top 1000 list for the first time in 1925.
 
Because it was outlawed for so long, Brian may feel like a less classic and ancient name than it really is. Its massive popularity in the 1970s, when it ranked in the Top 10, makes it one of today's quintessential Dad Names.
 While Brian has been trending downward in the US for decades, it still ranks solidly in the Top 1000, where it will likely remain for decades to come. Bryan, Bryant, and Brianna are common variations.
 
Brian has some pretty diverse associations—to newscaster Williams, the movie Monty Python's Life of Brian and as Marilyn Manson's real name.

Clayton is one of those names that feels like it could be recently popular but does in fact have a long history of use. It has made the US Top 400 every year since the records began, and though more recently it has been in decline, it is still given to more than 1000 babies every year 

The name Clayton derived from Old English and translates to "clay town". Historically used as a place name and as a surname, it has been a given name since at least the 19th century. Smart but cool, Clayton also comes with the catchy nickname Clay. 
 
While Clayton has been falling down US the charts in recent years, across the pond, the latest UK stats reveal it is in fact trending upwards. Moreover, with the likes of Cooper, Carson, Colton, Weston, and Easton all in style, Clayton wouldn't feel out of place on a baby today.

Curtis is an attractive if somewhat dated surname name that has been borne by several significant musicians and athletes--think Curtis Mayfield, Curtis James Jackson III--aka 50 Cent, and also director Curtis Hanson. 
 In the USA, Curtis was in the Top 200 for most of the 20th century. We think Curtis, with is clean sound and nice meaning, will survive the all the trends that come and go, and remain in the Top 1000 for many years to come.

Enough parents have found naturalist Charles Darwin, the father of the theory of evolution, a worthy hero to keep Darwin relatively consistently in the Top 1000 (it dropped off in 2021 but is back in 2022)—though some might just like its trendy two-syllable sound. It has a lovely meaning too—"dear friend."

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.

Currently overshadowed by the bright and lively Leo, Leon feels a slightly more serious, more quietly confident than its short and trending counterpart. 
 
Just as leonine as Leo and Leonardo, Leon is popular across Europe, ranking in the Top 40 in Belgium, Switzerland, Norway, Poland, Germany and Finland. It has dipped in and out of the UK Top 100, but as of 2022, it is back. 
 
Leon peaked in the US in the 1920s, but it is on the rise again as parents turn to familiar-but-less-used alternatives to the most popular names. In 2023, it was in the US Top 200, and given to nearly 2500 boys. 
 A name with history, Russian Marxist revolutionary Lev Davidovich Bronstein is better known to history as Leon Trotsky. Leon (LAY-on) has been the name of three French prime ministers, while Leon Russell (born Claude) is a respected singer-songwriter.

Leon

Leroy's heyday was in the early twentieth century, when it was in the US Top 100 until 1949. As a result, it's now more frequently seen as a father or grandfather name rather than a viable newborn option. Though it has dropped off the popularity charts several times in recent years, it hasn't fallen into complete obscurity yet.

Lewis is the best spelling to choose if you want this pronounced with the S. Lewis has been in the Top 5 in Scotland since 2000, and is one that parents in the U.S. are just beginning to rethink.
 Lewis was a Top 100 name in this country from 1880 to 1930, reaching Number 30 in 1880. One of its most famous namesakes is Lewis Carroll, born Charles. A current bearer is comedian Lewis Black. Lewis is also a very common surname, as in Lewis & Clark, Jerry Lewis, Jerry Lee Lewis, Daniel Day-Lewis, Sinclair Lewis, Leona Lewis, and many other notables. Interesting fact: Louis Armstrong pronounced his first name as Lewis.
 Nickname/middle name Lou is making a comeback for girls (as in Keri Russell's Willa Lou), so why not Lew for boys?

To the thousands of girls who screamed the name of their favorite Beatle in the 1960s, the boys' name Paul had a thrillingly unique image, but to the rest of the world, then and now, it's a name that's so simple and yet so widely diffuse that it could belong to almost anyone. Paul is an ancient <a href="https://nameberry.com/boys-names">name for boys</a> -- popular in Roman and medieval times -- that's not very fashionable now, which can work in its favor, scarcity balancing simplicity. 
 Paul also has a rich religious background: Saint Paul (originally called Saul but baptized Paul after his conversion) was a cofounder with Peter of the Christian church, and there have been six Pope Pauls.
 Paul also boasts a wide range of name-sharing heroes, from Revere to Newman, Cezanne to McCartney. Some creative foreign versions are Pablo (Spanish), Paolo (Itlaian), Pavel (Russian) and Paavo (Finnish).
 Paul's single syllable also make it one of the most popular traditional <a href="https://nameberry.com/list/673/middle-names">middle names</a>.

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. It's already in the UK Top 100.
 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.

In the World War II era, Roger had nothing but the most positive associations, actually used by military personnel to mean 'Received and understood'--or A-OK, and though it is now on extended furlough, it does have a long and distinguished history. Introduced to England after the Norman Conquest of 1066, Roger soon became very popular there, with nicknames Hodge and Dodge, and had a long run later in the U.S, remaining in the Top 100 for 55 years.
 Roger has an impressive list of notable namesakes, both fictional and real. Roger Chillingworth is a major character in Hawthorne's classic The Scarlet Letter, and the name appears in works by Ben Jonson and Anthony Trollope. In sports, there have been Rogers Maris, Clemens, Bannister and Federer, in entertainment actor Roger Moore and Roger Daltry, lead singer of The Who. And of course, many of us remember Roger Ramjet from our childhoods.
 On the dark side, there is the Jolly Roger--a pirate's black flag with skull and crossbones--which a little boy might actually love.

This strong single-syllable <a href="https://nameberry.com/boys-names">boys’ name</a> has been finding favor with parents since the fifties, though it's been slipping in recent years; it fell out of the Top 500 for the first time since 1959 in 2015. Its main associations have been with the River Trent, whose name dates back to prehistoric times, and with former Mississippi Senator Trent (born Chester) Lott, and Trent Reznor (born Michael) of Nine Inch Nails. 
 In the eighteenth century, William Trent founded a settlement, which became the city known as Trenton (Trent's town), and that morphed into a first name for boys.
 (James) Trent Olson is the only brother of the three Olson sisters; Trent Ford has been seen on Gosford Park, The West Wing and Vampire Diaries. And the name of the Vince Vaughn character in the 1996 movie Swingers is Trent.

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.

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.
