No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.
 Natalie Appleton, Tom Dumont, Jennie Finch, and Jessica Simpson all have little Aces. The best known grownup with the name is Ace Frehley, born Paul, one-time KISS guitarist.

Ace is a retro nickname most often used for boys, as in Ace Ventura. While some celebrities have adopted it for their sons, there's nothing that makes this name exclusively male.

Ander

Friendly, unusual, but a decidedly Old Country version of Andrew and one of the classic <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>. It made a brief appearance in the US Top 1000 in 2006 and then reentered in 2010. Its rising popularity could be attributed to the interest in Anderson, which has been gaining steadily over the last fifteen years.
Trivia tidbits: The patronymic Andersson is the second most popular surname in Sweden, and in Denmark, Donald Duck is called Anders.

Anders

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.

Archer

Archer is among the next wave of masculine-leaning occupational names rediscovered for girls.

As trendy as the chic Colorado ski resort and film festival, Aspen is fast becoming more popular for girls than for boys, but this nature name would work equally well for either.

Aspen

Aspen is part of two groups of stylish and unique baby names: <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a> and place-names. The name of a graceful tree in the poplar family with heart-shaped leaves so delicate they quiver in the gentlest breeze, Aspen is also the name of a trendy Colorado ski resort. Aspen started as a unisex name possibility but now is much more frequently worn by girls.
 Aspen entered the popularity list in 1993 and is a good bet to start climbing higher as more and more parents respond to the appealing place and nature image it evokes.

Asta as a boy's name is inspired by the Wizard King character in the anime series Black Clover. He is a human who triumphs in a world of superheroes --an inspirational figure.

Asta

This Scandinavian name was made famous in English-speaking countries as the name of the dog in the "Thin Man" series.  Danish actress Asta Nielsen was another famous bearer. Asta can be considered as a short form of Astrid or Augusta.

Atlas is one of those names that was previously thought too powerful for a baby boy, who would have to be strong enough to carry the world on his shoulders. Now Atlas has joined the pantheon of Greek and Roman god and goddess names in the realm of possibility, along with Mars, Zeus and Apollo.

 Atlas was one of the fast-rising names on the list in recent years in the USA, jumping from oblivion in 2012 into the Top 500 in 2015, and climbing several hundred places higher since then. Anne Heche was one of the first to make this audacious choice, but several celebrity parents have followed suit.

 As well as the mythological connection, Atlas is a cool geographical word name – perfect for the child of parents who love traveling or who hail from different parts of the globe.

Atlas

While Atlas is a decidedly male god and this name is in the US Top 300 for boys, it is used for an increasingly significant number of baby girls in the US. And undeniably, it's a name that imparts strength to any child.

 As well as the mythological connection, Atlas is a cool geographical word name – perfect for the child of parents who love traveling or who hail from different parts of the globe.

A classic in its native Scandinavia, Axel has a cool rock 'n' roll flavor in the US, thanks to Guns N' Roses' Axl Rose (born William). Axel is a popular Scandinavian form of the Biblical Absalom, who was a son of King David, and is the name of the title character of William Faulkner's Absalom, Absalom. 
 Growing in popularity, along with a lot of other names featuring the powerful letter 'x', Axel is now one of the most popular <a href="https://nameberry.com/baby-names/173/scandinavian-names">Scandinavian names</a>. It entered the popularity list in 1989, one year after the release of one of Guns N' Roses biggest hits. It is very popular in Scandinavia, Germany and France.
Axel was chosen by Will Ferrell for his third son, and also by Rob McElhenney and Kaitlin Olson for their boys, and it's the middle name of Tiger Woods' boy Charlie. Axel Foley was the character played by Eddie Murphy in the Beverly Hills Cop movies and, going further back, was the name of an important character in Jules Verne's Journey to the Center of the Earth. Currently, Axel Heck is the oldest son on The Middle.

Axel

A Top 100 name among boys, but a rare option for a girl. The French female form is Axelle (emphasis on the "elle").

Beau suggests someone devilishly handsome, with a large measure of southern charm—a nice image to bestow on your boy. Often solely a nickname in the past, it's now standing firmly on its own. Beau has been on the Social Security list non-stop since 1969.
 Beau also has something of a dapper image, thanks to the fashionable Beau Brummell (born George), which led to the stylish New York mayor Jimmy Walker being called Beau James. Other notable Beaus had more formal names at birth—Beaus Bridges and Biden were both the third sons in their families to carry their fathers' names: Lloyd Vernet Bridges III and Joseph Robinette Biden III.
 P.C. Wren's novel Beau Geste was a major bestseller in its day and was also a popular movie—in that case Michael was the character's birth name. Many will remember that the child of Ashley and Melanie Wilkes in Gone With the Wind was called Beau, and there was also a Beau on the old TV western Maverick.
 And if you want a more substantial name on the birth certificate, try Beauregard.
 Art Garfunkel, Emma Bunton, Wendy Wilson, Jamie-Lynn Sigler, and now Tori Spelling all have sons named Beau.

Beau

Billie

Billie is a tomboy nickname name, part of the growing trend for using boyish nicknames for girls and now destined for stardom along with its most famous contemporary bearer, music sensation Billie Eilish.
 To track its path from blue to pink, Billie was 100% male in 1880, was 55% female just a decade later, in the girls' Top 100 by 1928, and is now overwhelmingly female.
 Billie is a possible retro choice for fans of jazz great Billie Holiday, born Eleanora, and a very contemporary choice for teen singer Billie Eilish -- born Billie Eilish Pirate Baird O'Connell. Other conceivable namesakes are The Wizard of Oz's Glinda--Billie Burke (born Mary William), silent screen star Billie Dove (born Bertha), actresses Billie Whitelaw and Billie Piper (born Lianne) and tennis legend Billie Jean King (born Billie). Another cultural reference is the Michael Jackson hit song 'Billie Jean.'
 Billie was picked for their daughters by Carrie Fisher, My Name is Earl actor Ethan Suplee, and Rebecca Gayheart and Eric Dane.

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>.

Billy

Birch is a rarely used nature name that calls to mind the lovely image of the tall, strong but graceful white-barked tree. 
 The best known bearer of the name is former high-ranking Democratic Senator Birch Evans Bayh, who carried the name of his father and was the principal Senate sponsor of the Equal Rights Amendment.
 The birch tree has many notable qualities and uses &mdash; including the making of furniture, paper, canoes, and drums, is considered the national tree of Russia (where it used to be worshiped as a goddess), the state tree of New Hampshire, and has spiritual significance in several cultures.

Birch

One of the rarer tree names, Birch evokes imagery of the beautiful paper-white bark tree. Although a unisex name, the most notable people named Birch are men, such as Indiana senator Birch Evans Bayh Jr. Birch trees are very symbolic in many cultures. In Russia, birch trees are emblematic of grace, beauty, and strength. In Celtic culture, birch trees represent growth, stability, and adaptability.

Birdie was until recently a middle-aged Ladies' Club member wearing a bird-decorated hat --but now it's just the kind of vintage nickname (think Hattie, Josie, Mamie, Millie) that's coming back into style in a big way. Actress Busy Philipps named her baby Birdie (inspired by First Lady Lady Bird Johnson), as did soap star Maura West.
 In an earlier heyday of nickname names--the 1880's--Birdie was a Top 200 name.

Birdie

Originally a form of the saint's name Blaise, though now more likely to be a hot word name used for both sexes, though heavily weighted toward the boys. It has been in the boys' Top 1000 since the year 2000.
 br>On the pop culture side of things, Blaze Bayley is a singer and musician who has been connected to the bands Wolfsbane and Iron Maiden.

Blaze

A hot name, though perhaps not in the sense you want for your baby. About 20 times as many boys as girls were named Blaze in one recent year, perhaps because it can be seen as a spelling variation of the classic male saint's name Blaise.

Among the coolest of the cool color names, particularly popular with celebs as a unisex middle name. 

Blue

Blue suddenly came into the spotlight, as the unusual color name chosen by Beyonce and Jay-Z for their baby girl Blue Ivy. Blue is also a starbaby middle name du jour, used for both sexes in different spellings and forms, from John Travolta and Kelly Preston's Ella Bleu to Alicia Silverstone's Bear Blu. Dave 'The Edge' Evans named his daughter Blue Angel back in 1989.
 Blue is the heroine of the trendy Marisha Pessl novel Special Topics in Calamity Physics.

Now that the popularity of Brooke is waning, and surname style variant Brooks is on the rise, Brook seems live a newly fresh nature-inspired option.

Brook

Brooke variation – or is the other way around? – that makes it more a nature name, less an eighties-style androgynous name.

Casey is a name with a big wide grin, Irish, friendly, and open, and associated with several American folk heroes--Casey Jones, the engine driver of the Cannonball Express who gave his life to save his passengers, and the legendary Casey at the Bat.
 Casey was at its height of popularity in the 1980s bur recently has started climbing the charts again in the US, maybe because some of the Caseys born in the 1980s have become famous in the 2020s.

Casey

One of the original unisex Irish surname names, energetic Casey bounced onto the scene in the 1960s, then peaked in the 1980s for both boys and girls. Today Casey is having a resurgence for both girls and boys and re-entered the charts on the girls' side, likely due to the character Kayce Dutton (pronounced like Casey) on the hit show Yellowstone.
 "Casey at the Bat" is an 1888 poem by Ernest Thayer.

Chris is a long-running nickname used almost equally for boys and girls.  While past its prime, Chris stands out as sounding completely appropriate for both sexes, perhaps because of its widespread use as a short form of both the popular Christopher and Christine.  Chris manages to retain its crisp appeal even though its fashion moment is over.

Chris

Chris is one of the longest-running and still most appealing unisex short forms, still used nearly equally for boys and girls.  Though no longer fashionable, Chris still feels crisp and appropriate for both sexes.

Heavenly French word name used for both sexes.

Ciel

This simple yet evocative French word name was chosen for her daughter by model Niki Taylor.  While Ciel may be pronounced in French with two syllables, many will pronounce it as "seal" and there may be confusion with Celia and sister Ceil.

In The Hunger Games series, Cinna is the influential costume designer for Katniss. In ancient Rome, one Cinna was the father-in-law of Julius Caesar and another was a conspirator against Caesar.

Cinna

Associated with a vivid red-orange-colored lacquer, would make a more than distinctive color-related choice. 

Cinnabar

Clancy, one of the original crossover Irish surname names, is as energetic and appealing as ever &mdash; full of moxie, more distinctive than Casey, and also one of the less obvious of the red-headed names.
 A literary namesake is Clancy Sigal, author of the autobiographical novel Going Away, and there is also the comical mid-century song, Clancy Lowered the Boom.
 More common as a last name than a first, Clancy has gained fame via the Irish folk music group the Clancy Brothers, and one of the bestselling authors of all time, Tom Clancy, known for his espionage and techno thrillers.

Clancy

Irish surnames are hot, and this one can successfully cross the line to work for girls, replacing the outdated Casey. And only a dozen girls were named Clancy in the US in one recent year (along with 27 boys), making it one of those rare Irish names that are both accessible and distinctive, classic and cool. Clancy is a winner for either gender.

Coda

Typically used for girls, but Disney Channel show Big City Greens made it wearable for boys as well.

Cricket

Nickname name from the era of Father Knows Best, though we can see it making something of a comeback, a la Clover and Pippa. Cricket has new potential especially since it has recently been chosen by Busy Philipps. Still, it's one of the quirkier <a href="https://nameberry.com/search/girls-names/c">girl names starting with C</a>.

Crimson is a rare unisex color name used more frequently among baby girls.
 
The word "crimson" was derived from the name of the Kermes insect which produces the dye associated with the color. The insect name evolved from the Arabic word qermez, meaning "red."

Crimson

Crimson could be a possible competitor for Scarlett's success, though it's lacking that Johansson charm.
 
Crimson tends to be disproportionately popular in Alabama — the University of Alabama's athletic teams are called Crimson Tide.

Crys

Baby girl Danas outnumber baby boys with the name nearly ten to one. But Dana is an attractive, sleek name that can certain work for babies of either gender.

Dana

This name found in both Celtic and Scandinavian mythology has gone from all-boy to almost all-girl, retaining a strong, unisex quality. However, it has dropped following its three-decade heyday from the 1960s to the 1990s.
 Dana is the birth name of Queen Latifah.

Dane is a more masculine Dana alternative, with added style edge. Dane has been on the US Top 1000 for more than seventy years, having entered the list in 1945.
 Dane makes a great middle name, as evidenced by January Jones' use of it for son Xander Dane.

Dane

This rarely heard name pares down all the ultrafeminine Dan names to one that's much more powerful, for both boys and girls. 

Daniell

Dany

There is some controversy over the origin and meaning of this name, though most reputable sources define it as a Hindi name meaning kindness or compassion. Also spelled, Daia, other sources say it may mean "joy" or be a Hebrew name with the meaning "bird of prey". It has recently been made familiar through the character of Daya Diaz on Orange is the New Black .

Daya

Dee is a slight midcentury nickname that might be short for Deanna or Denise, but might be too slight for today's strong, independent female.

Devan

Deven

Devilishly handsome, Devin arrived as Kevin was moving out. Not to be confused (though it often is) with the English place-name Devon. While both Devin and Devon are flagging somewhat for boys, the names have dropped out of the Top 1000 for girls, making it more a masculine and less a unisex name these days.

Devin

Used far more for boys with this spelling, but still has a nice impish Irish feel for a girl. 

Devon, spelled like the lovely seaside county in Britain that inspired the name, has crashed since its heyday around the Top 100 in the 1990s. Despite its use as a female name, for example for Devon on the TV show The 4400, Devon continues to be far more popular for boys than for girls.

Devon

This spelling of Devon, as opposed to Devin or Devan, makes it a pretty and popular British place-name, evoking the beautiful county of farmlands and dramatic seascapes and moors in southwest England. A stylish ambi-gender name particularly well used in the early nineties, Devon remains an attractive option--though be aware that at this point in time, it is used more frequently for boys.

Devyn

A sweet and simple multicultural choice which has several different meanings and origins.

 Widely used in Africa, it means "love" in Lembaama.

 It's a variant spelling of Diya, an Arabic, Hindi and Sanskrit name meaning "lamp, light". 

 Dia is also a variant spelling of Dea, from the Latin dea "goddess".

 It also coincides with the Spanish word for "day".

Deejay

Solemn but soaring name with patriotic symbolism. 

Eagle

For the boyds.  Er, boys, if only judging my the statistics, which have this rare bird name given to a handful of baby boys in the US but no recent baby girls. But it certainly would make a majestic choice for a child of either gender.

Although this is traditionally seen as a female name, via the classical mythological nymph who pined away for Narcissus until all that remained of her was a disembodied voice — it can also be used for boys. Remember that old song, 'Little sir echo, how do you do?'
 
Amanda Knox has a son named Echo and a daughter named Eureka.

Echo

Echo, the pretty, resonant name of a legendary nymph, was the heroine of Joss Whedon's sci-fi series Dollhouse. Nick Hexum, of the band 311, named his daughter Echo Love.
 In the Greek myth, Echo was a nymph whose unrequited love for Narcissus caused her to fade away until all that was left was the sound of her voice. Obviously, a name with a lot of reverberations.
