Bowen is a Celtic surname representing two separate Celtic strains, one Welsh and one Irish, and entered the US Top 1000 for the first time in 2011.
 Football Hall of Famer Drew Brees named his son Bowen, as did a recent reality show couple looking for the perfect name to 'brand' their baby. It does have the appealing nickname Bo.
 
Alternatively, this is also a Chinese name, combining Bo and Wen, in which case the meaning would be 'wave of writing" or "wave in literature".

Bowen

This is the original Gaelic spelling of the Anglicized Colin -- more authentic, yes, but could make your American child's life unnecessarily complicated. 

Cailean

Once a cavalier Mississippi gambler type name, Chance has entered the mainstream since being endorsed by such celebrity dads as Larry King and Paul Hogan. Chance the Rapper has also boosted the name's popularity.

Chance

Thanks to its dashing Anglo-Irish image — due partly to Colins Firth and Farrell — and its C-initialed two-syllable sound, Colin and its cousin Collin have enjoyed a long run of popularity, reaching as high as Number 84 in 2004. 
 The usual pronunciation of Colin is COLL-in, but the alternate COLE-in version was publicized by General Colin Powell, the first U.S. African-American Secretary of State, who was named after World War II hero Colin Kelly.
 Literary cred: Colin Craven is a character in The Secret Garden, and Colin Creevey appears in the Harry Potter books.
 Both Kevin James and Kiss's Paul Stanley have young sons named Colin, while Tom Hanks has a grown one.

Colin

Corin was used by Shakespeare in As You Like It, an unusual name that could make a more distinctive alternative to Corey or Colin. It is a name used in the illustrious Redgrave family of actors.

Corin

CURAN

Curran is a common surname in Ireland, but unusual even there as a first. With its savory feel, calling to mind curry and currants, Curran can make for an attractive update on Colin or Connor. 

Curran

Emmett, honest and sincere, laid-back and creative, is on the rise as a male cognate of the megapopular Emma and Emily, not to mention being a character in the popular Twilight series.
 Emmett originated in England as a masculine diminutive of the German Emma; the Hebrew characters pronounced eh-MEHT mean truth, so that might be considered another definition. Emmet is another, less popular spelling.
The death of young Emmett Till helped spark the civil rights movement.

Emmett

Though it's a new name, sounds almost as dated as GARY and DARREN.

Garren

After being one of the hot upscale surnames of the nineties, Garrett has left the Top 100 and this streamlined spelling is dawdling near the bottom of the Top 1000. 

Garret

A rarely used last-name-first-name, never as popular as cousins Garrett or Derek. 

Garrick

Gavin, a name with Scottish roots, has stepped into the spotlight, replacing the dated Kevin, thanks in part to pop-rock sensation Gavin DeGraw and Bush lead singer Gavin Rossdale. 
 Gavin also has made literary appearances in J.M. Barrie's The Little Minister and in William Faulkner's Snopes family trilogy. In the form Gawain, he was one of the Knights of King Arthur's Round Table.
 Gavin entered the ranks in the 1950's and climbed as high as Number 30, in 2008, before dropping a bit on the charts.

Gavin

With roots in both Polish and Low German, Gerik is a blank slate of a name that has never made the charts. It's a possibility as a fresh twist on Eric or Derek.

Gerik

Greyson and Grayson, nephews of Jason, are both on the fast track. Both variations have made their way all the way up to the Top 100 since 2016. Gray/Grey makes a nice nickname.

The name of the child in The Nanny Diaries is Grayer, and actor Tyler Christopher opted for the unusual spelling of Greysun for his son. Some parents are considering Grayson -- or Gracen or Gracyn -- for girls as an androgynous spin on Grace.

Greyson

A familiar and usable last name turned first. Or you could look at it as a homophone of the verb howl, which gives it a wilder feel.

Howell

In the Old Testament, Joel was one of King David's 'mighty men' and the name was taken up by the Puritans of the sixteenth century. In the mid 1960s, Joel entered the Top 100, and stayed there for about twenty years, as parents tried to jazz up and formalize old standby Joe by reviving this biblical name.
 Current notable bearers include entertainer Joel Grey, half of the filmmaking Coen brothers, musician Joel Madden, and TV's Joel McHale. Joel Chandler Harris created Uncle Remus.

Joel

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

Juri

Lachlan is as Scottish as haggis and tartan plaid kilts—a favorite used throughout England, Scotland, Australia, and New Zealand—and just beginning to be noticed in the US: it reached the Top 1000 for the first time in 2013. An ancient name, Lachlan was originally used to describe the Viking invaders of Scotland, those from the land of the lochs.
 Americans and Australians tend to pronounce the first syllable of the name like Lock, but the genuine Scottish pronunciation sounds more like Lack.
 In Ireland, the name was Anglicized as Laughlin; in Scotland the pet forms are Lach, Lachie, or Lockie.
 Lachlan has been a top name in Australia for at least a decade. It has been in the headlines recently via the eldest son of media mogul Rupert Murdoch.
 Somewhat surprisingly, Lachlan has US presidential cred, as the son of tenth president John Tyler, whose other children included Lyon, Letitia, Tazewell, and Pearl.

Lachlan

This first name was once a surname derived from Old English. Used quietly a century ago, the current fashion for two-syllable boy names ending in n makes this one a new hit.

Layton

A somewhat stiff and serious turn-of-the-last-century name that seems to be coming back to life. Brendan Fraser chose it for his son in the mid-2000s. Leland Stanford was the founder of Stanford University and one-time Governor of California.

Leland

Leo is a strong-yet-friendly name that was common among the Romans, used for thirteen popes, and is now at its highest point ever in the US thanks in part to Leonardo "Leo" DiCaprio.

Derived from the Latin meaning "lion", Leo is one of those names, like Luke and Finn, that many people assume must be short for something but that is authentically a complete name in its own right. That said, Leo can but short for any number of names, from Leonardo in Latinate languages to Leon and Leopold in Germanic languages. We've even heard of little girl Leonoras and Leonies called Leo: How cute is that?

Leo's simplicity makes it an international star, ranking in the Top 100 in countries as diverse as Ireland and Israel, Spain and Sweden, Austria and Australia. Leo is a truly diverse name, a perfect choice for any family crossing countries or blending cultures.
 
Leo's only real downside is its universal popularity and familiarity. If you call your child Leo, you and they will almost certainly encounter many other Leos over the years of all types and ages. Plus or minus? Or both?
 
Penelope Cruz and Javier Bardem called their son Leo, as did actress Kim Raver, NASCAR driver Jeff Gordon and Kristin Olson. 
 Famous Leos of the past include Pope Leo the Great, a number of early saints, and Leo Tolstoy, as well as Dead End Kid Gorcey, colorful baseball manager Durocher, influential gallerist Castelli and the leonine MGM icon. There have been Leos seen on everything from The West Wing to Charmed to Grey's Anatomy to Seinfeld's Uncle Leo.

The related Lucas and Luke are both hugely popular boy names in the US and internationally, and now Luca has joined them on boys' popularity lists around the world.

That's an astonishing success story for a name that was virtually unknown a generation ago. Only 13 baby boys were named Luca in the US in 1980, and by 1990 it was still only 32. But by the turn of the century, Luca took off and has now surpassed his more familiar brother Luke in the US.

Boy names ending in vowel sounds may have felt too feminine to early generations who lived by more conventional gender rules. And that old school he-man America also may have rejected names like Luca for being too "foreign". But in this era of Noah and Mateo, Elijah and Ezra, Luca has finally found widespread acceptance.
Along with its popularity in the US, Luca ranks highly in a range of countries that speak English, Spanish, French, and German, among others. While Luca is technically related to Luke and Lucas and so takes their ancient Roman habitational meaning, you might also see it as a relative of Lucius or Lucian, meaning light.
 Colin Firth and his Italian wife chose Luca for one of their sons, as did Hilary Duff, Vincent d'Onofrio, Rebecca Minkoff, and Jacinda Barrett and Gabriel Macht.

Luca

Owen, a resonant Celtic name, has ranked among the Top 100 boys' names in the US for 20 years and is now at its highest point ever.
 
Why do so many parents love Owen? It's a classic with a genuine history, yet it's right in step with the modern trend for two-syllable, n-ending boys' names. Owen-like choices with less tradition behind them include Logan, Bowen, and Rowan.
 Owen is derived from two names—the Welsh Owain and the Celtic Eoghan. Each are connected to Eugene, which ultimately came from the Greek word eugenes, comprised of the elements eu, meaning good, and genes, "born." 
 
Owen became a Welsh patronymic surname during the Renaissance. The legendary St. Owen was a Benedictine monk who was a follower of St. Chad.
 
In Ireland, Owen may be spelled Eoin, as in Irish writer Eoin Colfer, and Eoghan. Other similar names include the Scottish Ewan or Euan and the French Ouen.
 
Owen's popularity now extends beyond English-speaking countries to France, Belgium, and the Netherlands.

Owen

This gentle Scandinavian name, soft and sensitive, is being discovered in a major way by parents in the US. It's most closely identified with the nineteenth century philosopher Soren Kierkegaard, but there have been modern fictional Sorens as well, in The Matrix Reloaded and the book series Guardians of Ga'Hoole, Charlie and Lola, and Underworld.

 In Scandinavia this name would be spelled as Sören or Søren, leading to it being pronounced "Sur-en". But with a plain old English "O", "Sorr-en" would actually be the correct (and more English-speaker friendly) pronunciation.

Soren
