Aidan is an ancient Irish saint's name with a fire meaning that's mega popular for boys, most often spelled as Aiden. The name is occasionally used for girls, sometimes as Aidyn or Ayden, as well. Aidan was the name of a famous seventh-century Irish saint, and is related to the Irish word for fire.

Aidan

Aiden/Aidan is just beginning to wander into the girls' side of the name popularity list, but it's so huge for boys in all its spellings that it will be a long time before it can be called a unisex name.

Nearly 8000 baby boys were given the Aiden spelling alone in the US last year, and only 43 baby girls -- less than one percent of the total.

Aiden

Aiden in all its spelling variations is the Anglicized version of the Irish Aodhán, which was originally a pet form of the Irish name Aodh (pronounced 'ee'), who was the old Celtic god of the sun and fire. St. Aidan was a famous seventh century Irish saint, noted for his kindness and generosity and for spreading Christianity.
 
Aiden has been a spectacular name success story—especially if you add all its various spellings together. Counted together, Aiden in all its versions is still a Top 10 boys' name.
 
The Aiden spelling has become the predominant version of the name in the US, followed by Ayden -- and then, in order of popularity, Aidan, Adan, Aden, Aydin, Aydan, Eiden, Aidyn, Eydan, Eyden, Adin, Aedan, and Aiyden. And then there's a pack of popular rhyming offshoots such as Brayden and Kaden.
 
Irish actor Aidan Quinn introduced the name to the US. The Aiden spelling was used by actress Tracey Gold and Rod Stewart for their sons.

Arlo, an unexpectedly popular name for boys these days, is also finding new life as a girls' name. The first name Arlo may be rooted in the surname Arlow or the place name Aherlow, meaning "between two highlands". As a surname, it also has roots in a place name meaning "rocky hill".

 Arlo is a name with several unexpected lives thanks to celebrity associations. It was first known as the name of folksinger Arlo Guthrie, son of Woody; then it was revived by television's "Justified" character Arlo Givens. Now it's been spun again as a girl's name first by actor Johnny Knoxville and then by celebrity couple Leighton Meester and Adam Brody, who chose it for their daughters, no doubt inspired by soundalike girl names like Harlow and Marlowe.

 Arlo Parks (born Anaïs Oluwatoyin Estelle Marinho) is an up-and-coming British singer-songwriter, winner of the Brit Award for best new artist and the Mercury Prize for album of the year in 2021. 

 A growing number of girls are named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this cool retro name more into sleek surname territory.

Arlo

Quirky cool Arlo is now well and truly back. Last year it broke into the US Top 200 boy names and consistently ranks among the most popular boy names on Nameberry. 
 Arlo is even more popular in the UK, Australia and New Zealand. Arlo is also one of the top baby names among Nameberry's visitors from leading US cities.

 
Once strongly associated with shaggy singer Arlo Guthrie, Arlo has an animated and cheery feel, thanks to its upbeat o ending. It was chosen by Toni Colette for her son in 2011, which brought the name back into the spotlight. Previously, Arlo was in regular use in the first half of the twentieth century—it was Number 667 in 1915, for example, but it had dropped off the charts in 1944.
 Arlo has many possible derivations along with its Irish and English roots. It may be a shortened form of the Italian name Carlo or the Spanish Carlos, and in Basque-speaking regions it is the word for area. In English, Arlo was used as a place name, Arlo Hill, by Edmund Spenser in his epic poem The Faerie Queene and is thought to derive from the Celtic word Aherlow, meaning "between two highlands."

 A growing number of girls are also named Arlo in the US each year, with a handful more babies of both sexes receiving the Arlow and Arlowe spellings, which take this name more into smart surname territory.

The poetic, soft-spoken Auden has recently started to be considered as a first name option, used for both sexes, appreciated for its pleasing sound as well as its link to the distinguished modern Anglo-American poet W.H. Auden.

Auden

Avery is a hugely popular name in the US, especially for girls. But while nearly four times as many girls as boys are named Avery today Avery's popularity is starting to soften for girls while it continues to strengthen for boys.

Unlike many gender-neutral surname-y names popular today, Avery began life as a first name and later became a patronymic last name. It originated in the Middle Ages as a Norman-French pronunciation variation of the Anglo-Saxon name Alfred and the Ancient Germanic name Alberich. The elements aelf, meaning "elf" and ric, meaning "ruler" give Avery its meaning. 
 
Angie Harmon and Jason Sehorn may have started it all when they chose it for their daughter in 2005, just as they did with daughters Finley and Emery. Amy Locane used the name in 2009 and now Dr. Phil has a granddaughter named Avery.
 
On 30 Rock, Elizabeth Banks had an extended cameo playing Alec Baldwin's glamorous fiancée, Avery Jessup.

Avery

Avery is a unisex name that is used four times as often today for girls as for boys. But while Avery's popularity is starting to soften for girls, it continues to get stronger for boys -- in keeping with our finding that gender neutral names are becoming more favored for boys than for girls. 

This stuffy English surname and hotel name took on Twilight cool when attached to vampire Carlisle Cullen.  Inspired by the character, it's more popular in this spelling than as Carlyle and more widely used for boys than for girls.

Carlisle

Carlisle may be a male name in Twilight (he's vampire hero Edward's adoptive father), but in the real baby naming world, it's used about a quarter of the time for girls. Unusual now, we think Carlisle (or Carlyle) has the potential to be the next Carter.

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.

Devon

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.

Elliot is another traditional <a href="https://nameberry.com/list/79/boy-names-for-girls">boy name used for girls"</a>, a trend led by political commentator George Stephanopoulos and his actress wife Ali Wentworth. 
 Variously spelled Eliot, Elliot, Elliott and Elliotte (used by Marla Sokoloff), its star is definitely on the rise for girls. Bonus for girls is cute and feminine nickname, Elle. And many parents, of course, choose Elliot to get to the trendy short form Ellie or even Ella. At this point, Elliot has become one of the most popular <a href="https://nameberry.com/search/unisex-names/e">unisex names starting with E</a>.
 Dr. Elliot Reid was a female character on Scrubs.

Elliot

Elliot (which boasts several spellings depending upon how many 'l's or 't's you want to use) is a winner -- it has the ideal quality of being neither too common nor weirdly unique. Elliot had a style boost back in the early 1980s via the young hero of the movie E.T. , who was named Elliott. Since then there have been Elliots on Law & Order: SVU and Mad Men.
 Elliot namesakes include composer Carter, actor Gould, and photographer Erwitt.

Evan is a boys' favorite that has been given the feminine touch by talented actress Evan Rachel Wood.  If you want to move beyond Eva and Evelyn and like unisex names, this may be a good bet for you (though like Evan Rachel Wood, you may want a feminine name in the middle name position to clarify matters). Evanna is also another alternative.

Evan

Evan has a mellow nice-guy image that has kept it popular, while it has been widely used in Wales since the nineteenth century. And interestingly—and surprisingly—enough, Evan charts highly for boys in France.
 Evan was derived from Iefan, a Welsh version of John. John is ultimately a derivative of the Hebrew name Yochanan, comprised of the elements yo, meaning "God" and chanan, "to be gracious." Evan is actually a Hebrew word itself, meaning "rock."
 
Jenny McCarthy has a son named Evan, and some other modern associations are former Senator Evan Bayh, novelist Evan Hunter, and the movie Evan Almighty. It is also sometimes used for girls, as in actress Evan Rachel Wood.

Hadley, most famous as the name of Ernest Hemingway's first wife, is more sophisticated, professional, and modern than cousins Harley, Haley, or Hayden. 

The hit book The Paris Wife, a novel by Paula McLain told from the point of view of Hadley Hemingway (born Elizabeth Hadley Richardson), has helped popularize the name, which also appears on the vampire show True Blood. Hadley could become this generation's Hailey.

Adley, a mashup of Hadley and Addie, has also appeared on the scene.

Hadley

Hemingway readers will recognize this as the name of Papa's first wife (and, eventually, actress Mariel's grandmother). But in Victorian times, Hadley and Hedley were actually more popular for boys.

Once a macho biker name, Harley is now showing its softer side. In the UK, Harley is predominantly masculine, but it's currently more popular for girls than boys in the US.
 Along with Harper and Hadley, we think it will climb even further. In England, it's associated with Harley Street, home to some of London's most prominent medical specialists.
 A famous fictional namesake is Batman's Harley Quinn, "born" Harleen Quinzel. DC Comics movie Suicide Squad from 2016 was probably part of the reason for the increase in the number of girls named Harley. Harley Cooper was a character who was introduced on the soap The Guiding Light in 1987—that Harley was named after her father's favorite motorcycle.

Harley

You can ride one, you can use it as a baby name – or, as is often the case, both! Harley is currently trending up for girls and down for boys in the US, although it remains predominantly masculine in the UK. A lesser-used -ley ending choice for boys, Harley has a current sound but an old-school biker appeal.

James for a girl? Believe it or not, this is one of the <a href="https://nameberry.com/list/79/boy-names-for-girls">boy names for girls"</a> gaining a lot of attention these days, since Blake Lively and Ryan Reynolds shocked the world by choosing it for their eldest daughter in 2014 (after his late father).
 
Since then, it's become something of a celebrity baby middle name du jour, with high-profile parents including Coco Rocha, Kristin Cavallari, Nev Schulman and Brandon Jenner all having daughters with James in the middle spot.

James

James is one of the classic Anglo-Saxon names, a stalwart through the ages that is more popular—and yes, stylish—than ever today. It recently came out Number 1 in a poll of America's favorite boys' baby names, and is the most common male name, counting people of all ages, in the US.
 James, which reentered the Top 5 in 2016, is a current favorite among fashionable parents looking for a baby name that has both style and substance. Like Henry and Theodore, it manages to combine these two stellar qualities.
 
An English derivation of the Hebrew name Jacob, James is biblical (the name of two apostles in the New Testament), royal (kings of both England and Scotland), and presidential (with more U.S. Chief Executives -- six -- than any other name). The name James is also shared by countless great writers and entertainers.
 
There are fewer Jimmys, Jimbos or even Jamies these days; the most fashionable form of the name is James itself. Several stylish celebrities have chosen it in recent years for their sons, including Sarah Jessica Parker and Matthew Broderick, Liz Phair, Colin Farrell and Isaac Hanson. Brendan Fehr thought out of the box and named his daughter James, which has now become a fashionable middle names for baby girls..
 James has some interesting foreign variations: Diego and Jaime (Spanish), Jacques (French), Giacomo (Italian), Hamish (Scottish), Jaako (Finnish), Seamus (Irish), Jaap (Dutch) and Jago (Cornish).
 Along with being one of the most popular first names in the US, James is also one of the <a href="https://nameberry.com/blog/top-last-names-in-the-us">most common American last names </a>.

The number one surname in Denmark could make a sophisticated and stylish girl's name. Jensen Huang is the (male) cofounder of AI giant Nvidia.

Jensen

A variation of Jenson, which is actually more popular than the original in the United States. This spelling also holds the distinction of being the most common surname in Denmark.
 The most famous Jensen these days is Nvidia cofounder Jensen Huang. Huang's name is an Anglicization of his Chinese name Jen-Hsun.
 Jensen Ackles, best known for his portrayal of Dean Winchester on the hit television show Supernatural, has brought this name into the spotlight.

Kit is a crisp, old-time nickname with plenty of spirit and style. In the UK it's a rising star for boys, while in the US, it is trending upwards for girls too. Originally used as a diminutive of Katherine and Christopher, Kit could make a cool alternative to Katie, or an unexpected honor name for the aforementioned classics. 
 
Coinciding with the name for a young fox, Kit feels at home with the likes Wren and Quinn — and with fast risers like Scottie, Robin, and Drew. In 2023, around 130 girls received the name compared to 180 boys. 
The year prior, however, the scales were tilted the other way, with 160 girls and 140 boys receiving the name. With its unisex potential then, and its sharp, clear sounds, Kit may well see more use across the board in coming years. 
 <
Love the idea of Kit for a girl but still want a full name that isn't Katherine or Christina? You could try Kallista, Kensington, Keturah, Kismet, Kinneret, or Katalina.

Actor Kit Harington, aka the dreamy Jon Snow on Game of Thrones, has given this nickname-name new style and appeal for boys. Actress Jodie Foster used it for her son. 
Kit is one of those names that is gender-neutral but has a different derivation for boys and girls. For boys, it originated as a short form of Christopher, while for girls, it's an updated diminutive of Katherine.
Kit as a full name is still beneath the Top 1000 for both sexes in the US, but it's getting more popular. In 2022, 166 baby girls and 137 baby boys were named Kit, up from 104 and 129 in 2021.

Though this name of a sturdy tree that can live for centuries was quite popular for boys in the first half of the twentieth century, at this point in time we can see Linden as a fresh-sounding possibility for a little girl named to honor an Aunt Linda. 

Early pagans and Christians embraced the Linden as a holy tree, thought to aid healing and often planted near churches. The Linden is the mythological symbol of truth, peace, and justice; court cases and marriage ceremonies were often held beneath Linden trees. The Linden tree is associated with the goddess Freya.


Linden

The graceful, natural image of the verdant shade tree transcends any connection with President Johnson.
 A sturdy tree that can live for centuries, Linden was actually quite a popular boys' name from the 1930s to the 1960s--as was the presidential spelling Lyndon--but has now become unisex.

Logan, with its appealing Scottish burr, is a very hot boys' name—it's in the national Top 10 and heading for Number 1 in some states—and can also make a rich and resonant choice for a girl. Jason and Jordan Mewes have a daughter named Logan Lee.

Logan

According to exclusive Nameberry data, Logan is officially the Number 1 gender-neutral name in the US, but that statistic is somewhat misleading given that nearly 90 percent of the baby Logans born in 2023 were boys.
 
Logan started climbing in the mid-70s and shot up to the Top 5 for boys in 2017. Now, Logan's popularity has settled back down to the boys' Top 50 in the US and the Top 100 in other English-speaking countries.
 The mutant character Wolverine, known as Logan, based on the X-Men comics and played by Hugh Jackman on film, has had a considerable impact on the name. There were also attractive guys named Logan on Veronica Mars and Gilmore Girls, though Succession patriarch Logan Roy may have given the name a harder edge.
 
Logan originated as a Scottish surname which was derived from a place of that name in Ayrshire. The place name came from lagan, a Scottish Gaelic diminutive of lag, meaning "hollow." Alternate spellings include Logon, Logen, and Logyn, which is more common among girls.
 Logan is used for girls less often now than it was in the mid-nineties. A little over ten percent of the baby Logans today are female, down from about 15 percent in 1995.

Quinn is one of the first popular Irish unisex surnames, a strong and attractive choice on the rise for girls but still popular for boys. Quinn was used for about 3000 baby girls and 700 boys in the US last year.
 
Quinn is the Anglicized version of the Irish patronymic surname Ó Cuinn, meaning "descendent of Conn." Conn has two possible derivations—the Old Irish cond, meaning "intellect," or cenn, meaning "chief." One of the most notable Quinn clans was from County Tyrone in Northern Ireland. 
 Quinn started taking off for girls in the mid-nineties, possibly influenced by the popular show Dr. Quinn, Medicine Woman. Since then, there have been female Quinns on the animated MTV show Daria, on Zoey 101, and—most prominently—on Glee, featuring cute blond cheerleader character Quinn Fabray.
 Some other, more <a href="https://nameberry.com/lists/category/unusual-names">unusual names</a> with the Q-factor: Quincy, Quintina, Quintana, Quinta, Quilla--and, on a different note, Queenie.

Quinn

Quinn is an engaging Celtic surname that is still on the rise for girls but beginning to flag for boys. As a female name, Quinn is in the Top 100, used for over 3000 baby girls last year, but toward the bottom of the Top 500 for boys, given to 700 baby boys.
Pop culture was an important influence on Quinn's popularity for both genders. Quinn started leaning decidedly toward the feminine thanks to a female cheerleader character on the television show Glee. For boys, Quinn's popularity was influenced by "The Mighty Quinn," the name of a movie, a band, and a Bob Dylan song. 
 Sharon Stone has a son named Quinn. Other ideas for boyish names like Quinn: Quinton, Quincy, Finn.

Less than ten percent of the babies named Rhys are girls, whereas Reese is given five times more often to girls than to boys, thanks to Ms. Witherspoon.  It's a sleek and attractive name, but one that benefits from two accepted spellings that help clarify its gender identity.

Rhys

There's Rhys and there's Reese (now more popular for girls) and there's Reece, and we particularly like the traditional Welsh spelling, which entered the list in 2004, possibly influenced by Jonathan Rhys Meyers, of The Tudors, and Welsh-born actor Rhys Ifans.
 Always widespread in Wales, where it has deep historic roots, Rhys is also a high-ranking name in England, Ireland and Scotland.
 Former New Kid on the Block Joey McIntyre named his son Rhys Edward in 2009.

Stylish, gentle, and rustic at the same time, Rowan is a name that falls into various categories. Unisex and cool, mystical and woodsy, with the feel of both Rose and Riley, Rowan is a fresh but familiar choice.
 
The name has multiple origins, possibly deriving from the Irish Ruadhán, meaning “little redhead”, or from the names Rowena and Rhonwen, meaning “famous friend” and “white spear.” 
Alternatively, it might be taken from the rowan tree, a red-berried tree whose name derives from Old Norse and means “to redden.” In folklore and mythology, rowan trees are seen as a symbol of protection and of life, used to ward off evil. 
Rowan was an obscure name in the US before Brooke Shields chose it for her daughter in 2003. The name entered the US Top 1000 the same year and it’s been climbing in popularity ever since. Now, over 1000 girls are called Rowan every year, meaning for every 3 boys named Rowan, there’s 1 girl. 
Notable namesakes include the actress and activist, Rowan Blanchard, and Rowan Ellis, an author and Youtuber who makes video essays. In fiction, Rowan Mayfair is a powerful witch in Anne Rice’s novel The Witching Hour and Rowan Love is the quirky and creative older sister in Karen McCombie’s Ally’s World series.

Rowan

With its gentle sounds and earthy vibes, the name Rowan feels like a fusion of different styles. A word name, a surname, and a gender-neutral name, Rowan is rustic but trendy, blending the vibes of both Owen and Oakley. 
Just as it’s hard to fit Rowan into one category, it’s equally difficult to identify one definitive root. It could be considered an Anglicized form of the Irish name Ruadhán, meaning “little redhead” and it was used as an English surname before it became a given name. 
Alternatively, it could be linked to the rowan tree, whose name derives from Old Norse and means “to redden.” In folklore and mythology, rowan trees are seen as a symbol of protection and of life, adding extra meaning to Rowan. 
 To complicate matters further, some scholars identify Rowan as a girls’ name, deriving from Rowena and Rhonwen, meaning “famous friend” or “white spear.” This gives it solid credentials as a unisex name and lends it a slightly more rugged vibe. 
What is certain, however, is that Rowan has quickly become a stylish choice, chosen for over 3000 boys every year. Once an obscure name in the US, it rapidly climbed the charts during the 2010s and has now entered the Top 100 Boy Names for the first time. 
Rowan is popular in the UK, Canada, and the Netherlands too, but even more so among Nameberry users, where it ranks in the <a href=“https://nameberry.com/popular-names/nameberry/boys/allNameberry Top 1000”> Nameberry Top 30.</a> 
The most prominent bearer of the name is probably Rowan Atkinson, the British comic actor of Blackadder and Mr Bean fame. Other namesakes include the former Archbishop of Canterbury, Rowan Douglas Williams, and the Australian swimmer, Rowan Crothers. Pokémon fans and Sarah J. Maas readers might recognize it too as the name of a character in both the game franchise and in the Throne of Glass series. 
Gentle but powerful, stylish but not oversaturated, Rowan may well continue to climb the charts, so if you love Rowan but want to stray from the trends, Ruan, Sylvan, Lorcan, Lennox, Wren and Sloan might inspire you.

Sasha in all its forms -- which include Sacha and Sascha -- is rising in popularity for both boys and girls, especially with the Sasha spelling attached to one of the First Daughters.


Sacha

Sasha in all its forms -- which include Sacha and Sascha -- is rising in popularity for both boys and girls. Its most prominent current bearer is Sacha Baron Cohen.

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

A name with some sterling qualities, most associated with the British currency and silver markets. Sterling is more commonly a male name or surname, but is occasionally used for girls as well. 

Sterling

A name with some sterling qualities, most associated with the British currency and silver markets. Sterling has several recent TV associations, with characters Roger Sterling (on Mad Men) and Sterling Archer (on Archer), and actor Sterling K. Brown (on This is Us).

Though Tate is used almost exclusively for boys, we can see Tate as a stronger surname alternative to Kate or a clipped form of Tatum.
