Angus is a traditional yet stylish choice in the UK, especially in Scotland. And it's a cool choice for US parents too, particularly those whose roots go back to Glasgow. The ancient Celtic form Oenghus has important historical overtones in Scotland, and the Gaelic form Aonghas is associated with two distinguished modern poets. In Irish folklore, Angus Og is a chieftain-lord who used his magical powers for the pleasure and prosperity of mankind--and in Irish myth, Aonghus was the god of love and youth.
 These days, Angus is even more popular in Australia than Scotland, possibly due to the fame of Scottish-born Australian musician Angus Young, lead guitarist and co-founder of the seminal rock band AC/DC.
 Other pop culture references: Angus was the first name of TV's McGyver and the young actor who plays the half man on Two and a Half Men is Angus T. Jones. Angus Wilson was a noted British novelist and short story writer.

Archer is an Anglo-Saxon surname that feels more modern than most because of its on-target occupational and Hunger Games associations. And it's a nice way to bypass the clunky Archibald to get to the cool nickname Archie.
 But have a look at that amazing popularity chart below: After 1889, Archer took a 130-year nap, resurfacing on the Top 1000 in 2009 and now shooting straight upwards. Five years ago, we named Archer one of our Hottest Names of 2011—and, indeed, it jumped 102 places that year, thanks in part to Archer's similarity to popular Asher and its cross-gender appeal. Moms may like its literary gentility and dads its tough-guy FX cartoon appeal. Or, of course, vice versa.
 Trivia tidbit: Archer is the name of Dr. Doolittle's father.

This Irish name of a saint from the Isle of Aran also appears in myth and fantasy fiction, giving it an intriguing, mystical air. 
 Some modern parents are attempting to update the spelling, as in the actor Breckin (middle name Erin) Meyer or the most popular form of the name, Brecken.

Breccan

Brecken is a fresh, distinctively Irish alternative to similar-sounding (and much more popular) Beckett or Beckham. While Brecken is a spelling variation of the original Breccan, it's the most popular form of the name. By whatever spelling, it's a name we'll likely see rise in popularity.
 Spelled Breckin, it's the given name of actor Meyer, known for Road Trip and Rat Race.

Brecken

Both offbeat and upbeat, this evocative traditional Irish name that runs through Celtic mythology is known here via award-winning novelist Cormac McCarthy (born Charles). The author's adopted name is related to Cormac Mac Airt, one of the great legendary high kings of Ireland.
 In two of the Harry Potter movies, Cormac McLaggen is a Gryffindor student.
 And for all you popularity-phobes, Cormac has never yet made it onto the American Top 1000 list.

Cormac

Crosby is an attractively laid-back Irish surname with retro musical associations to Bing and Crosby, Stills, and Nash, and with a jaunty air. Crosby Braverman was the name of a character on the TV show Parenthood, played by Dax Shepard.
 Crosby entered the Top 1000 list for the first time in 2011.

Crosby

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. Most recently, it entered the UK Top 100 in 2022, replacing Ollie. 
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

Finley has been used for both sexes for enough years to become one of the most <a href="https://nameberry.com/unisex-names">popular unisex names</a>. Given nearly equally to boys and girls, Finley appeals to contemporary parents as a truly gender neutral choice. <br/
Finley is a Scottish royal name (it belonged to Macbeth's father) riding the wave of Finn names. Chris O'Donnell used it for one of his sons, and Angie Harmon and Jason Sehorn named their daughter Finley. 
 <br/Finlay is another, much less popular spelling. A boy Finley can be called either Finn or Lee.

Finley

Finnian is a fair jig of a name, energetic and easy on the ear. Finnian (and brother Finian) is also familiar in its alternate spelling through the classic 1968 Broadway musical Finian's Rainbow, later made into a film starring Fred Astaire as Finian McLonergan.
 There is also a St. Finnian who was a famous teacher and scholar.
 We think Finnian/Finian could really catch on in the wake of cousins Finn and Finlay/Finley.

Finnian

Following in the footsteps of popular brother Brady, Grady is another lively, ebullient Irish surname name. The O'Gradys (originally O Gradaugh) were an ancient clan that produced an impressive number of bishops.
 Perhaps the most remarkable O'Grady descendant is Muhammad Ali, whose mother's maiden name was Grady.
 Tampa Bay Rays outfielder Grady Sizemore was born Gradius.

Grady

Forget the furry blue Muppet, forget corpulent President Cleveland (not too difficult), and consider this name anew. We think it's spunky, a little funky, and well worth a second look. 
 President (Stephen) Grover Cleveland is actually a more than respectable namesake. The only president to serve two non-consecutive terms, he was well liked and respected. Many children were named in his honor, including the major league Hall of Fame pitcher Grover Cleveland Alexander. Another well known Grover is jazz saxophonist Grover Washington Jr.
 Not surprisingly, Grover was at its most popular as a baby name around the time of Cleveland's presidency;it was Number 20 in 1884 and 1885.

Grover

Jasper originated as a variation of the Latin Gaspar, which ultimately derived from the Persian word ganzabara, meaning "bringer of treasure." As a given name, Jasper’s etymology is unrelated to that of the gemstone, which comes from a Semitic word meaning "speckled stone." Jasper is the usual English form for one of the Three Wise Men who brought gifts to the infant Christ according to medieval tradition and appears in the Bible as a reference to the stone itself in Revelations 4:3.
 
Jasper has a lot going for it—it's been rocketing up the ranks in the US, after long being considered a posh and charming name in England. Distinctly masculine, Jasper represents a variety of quartz—one of the few gem <a href="https://nameberry.com/boys-names">names for boys</a>—and is the first name of the great modern artist Jasper Johns. Our only caveat: Jasper is a favorite of a lot of hip parents, and has gotten even more popular since its strong appearance in the Twilight books and movies.
 Jasper has considerable literary cred as well, appearing in works by Sir Walter Scott, James Fenimore Cooper, Thackeray, and Thomas Hardy--as well as Stephenie Meyer. 
 Casper/Caspar is the German version.

Jasper

Long popular in Ireland and England, Kieran, the name of Ireland's first-born saint and twenty-five other saints, has been building its U.S. fan base thanks to its strong and attractive sound, and its fashionable Irish brogue. While Ciaran is the more authentic Irish spelling, Kieran is more popular this side of the Atlantic. 
 Julianna Margulies chose Kieran for her son, and Kieran is a Culkin brother to Macaulay and Rory. Kier is an attractive short form, and Kiera/Keira is Kieran's girl twin.

Kieran

Knox is an old Scottish surname that Brad Pitt (whose great-great-grandfather was named Hal Knox Hillhouse) and Angelina Jolie took out of the back cupboard, dusted off, and elevated to coolness--to the point where it entered the <a href="https://nameberry.com/popular-names">popular baby names</a> list in 2009. Knox now ranks among the most influential <a href="https://nameberry.com/fameberry">celebrity baby names</a>.
 With Knox, the Jolie-Pitts established their own tradition: instead of their sons bearing the same first inital, they share the final letter 'x'--Maddox, Pax and Knox-- as well as a final 'n' for their <a href="https://nameberry.com/list/673/middle-names">middle names</a>. It's celebrity shine has made the formerly obscure Knox one of the most popular <a href="https://nameberry.com/list/473/scottish-names-for-boys">Scottish names for boys</a>. 
 The surname Knox dates back at least to the thirteenth century, and John Knox was the priest who brought about the Reformation in Scotland.

Knox

The additional syllable makes Lark a masculine surname name. 

Larkin

Appealing way, à la Dawson, to honor an ancestral Lawrence. Lawson is also an English pop rock band.

Lawson has history or use that dates far back, but it fell off of the charts in 1950. The name resurfaced in 2001 and has been climbing since. Lawson has that surname feel and -son suffix that parents are loving in recent years.

Lawson

Maddox, a previously obscure Welsh family name with a powerfully masculine image, suddenly came into the spotlight when Angelina Jolie chose it for her son in 2003. By the following year it was in the middle of the Top 1000, and it has risen since.
 It was Maddox who set the precedent for all the boys in the Jolie-Pitt clan to have names ending in 'x'-and helped fuel the spark for all names X. 
 Maddox is related to the traditional Welsh Madoc (pronounced MAH-dog), meaning 'fortunate'; it belonged to a bearer who, according to legend, colonized North America in the twelfth century.
 Maddox is a character in The Vampire Diaries; spelled Madox, it appeared in Michael Ondaatje's The English Patient.

Maddox

Odin is the name of the supreme Norse god of art, culture, wisdom, and law — who was handsome, charming, and eloquent into the bargain. The name projects a good measure of strength and power and has excellent assimilation potential.
 The god Odin was referred to by more than 200 names, including Yggr, Sigfodr, and Alfodr — none of which is recommended. The word Wednesday is derived from Woden, the English form of Odin.
 Odin came to be used as a Norwegian male given name beginning in the nineteenth century, originally in the context of a romantic Viking revival. In the 2001 novel American Gods by Neil Gaiman, the character called Wednesday is an incarnation of the god Odin.

Odin

Otto is cool again. Long a quintessential Old Man Name, Otto has been promoted to trending darling of adventurous baby namers. 
 Like most <a href="https://nameberry.com/baby-names/160/german-names">German names</a>, Otto fell out of favor during and after the two World Wars – it had been a Top 100 name in the years preceding. Off the Top 1000 from the mid-1970s until 2011, Otto is now headed straight uphill.
 <br/
There were some distinguished Ottos before the imperial image of Prussian Otto von Bismarck colored the name. Otto the Great is generally considered the founder of the Holy Roman Empire and there were several German and Austrian royals with the name. 

 Otto Frank was the father of Anne Frank, the young Jewish girl who wrote her famous diary during her family's years in hiding from the Nazis during World War II. She was killed in Bergen-Belsen concentration camp in 1945 and her father Otto typed and edited the diary himself to prepare it for publication. 

 Otto Hightower is a character in the Game of Thrones universe, played by Rhys Ifans in the HBO prequel House of the Dragon.

 Feminine forms of Otto include Ottoline, Ottilie, Odilia and Odette, all fashionable in the UK along with Otto itself.

Otto

Now that many dogs are named Max, it's safe to use this sleek, solid, regal name again for your child. And with the charm of its final x, its regal meaning, and its offbeat simplicity, Rex is definitely one to consider.
 Coldplay's Will Champion used it for his twin son, and Natascha McElhone gave her little boy the doubly cool appellation Rex Coltrane, and Niki Taylor — intentionally or not — gave her son the full name of the British My Fair Lady star, Rex Harrison (who was actually christened Reginald). And quite fittingly, Rex is name of a toy T-Rex in Toy Story.
 Other options: the French version Regis or the literal King.

Rigby is a rather stiff British surname, which might call to mind the Beatles "Eleanor Rigby" or, from the recent past, Cathy Rigby, the first American woman to win a medal in World Gymnastics competition.  The problem with Rigby may be its similarity to the word "rigid."

Rigby

This spirited Gaelic classic, which became popular in Ireland via the illustrious twelfth century king Rory O'Connor, makes a highly energetic choice, now used for either sex. Rory's gender split is still trending boyward; it's one of the coolest <a href="https://nameberry.com/search/boys-names/r">boys' names starting with R</a>. 
 In England and Wales, however, the name is virtually never given to girls. It's seen as thoroughly male (and non-female) as Roger or Richard.
 Rory first came to attention in the US in the person of mid-century pin-up boy Rory Calhoun (born Francis Timothy). The name entered the popularity list in 1947, peaking at Number 280 in 1959. 
 Young Irish U.S. Open champ Rory Mcllroy makes a worthy namesake. Bill and Melinda Gates chose Rory as the name of their only son.
 Rory is a popular choice all throughout the UK. Skip baffling Gaelic spellings like Ruari and Ruaidhri and stick with the more straightforward Rory.

Rory

Though to most Americans Viggo is a one-person name attached to intense actor Mortensen, it is actually an old Norse name dating back to the Vikings, and is currently the 32nd most popular appellation in Sweden. Viggo Mortensen is a Jr., sharing his name with his Danish father.
 
We think this name is so, well, vigorous, that it might appeal to others as well. Taylor and Natalie Hanson seemed to agree when they chose it for their fourth child.
