Newly fashioned but familiar and with an on trend, unisex feel, Addison seems like the perfect solution for anyone who can’t decide between Madison, Adeline, and Alison. 
Addison really took off in the mid-2000’s, making a spectacular jump from being outside the Top 100, to being nearly within the Top 10, just two years later. Undoubtedly influenced by the introduction of Dr. Addison Shephard to “Grey’s Anatomy”, the name was at its peak in 2009. 
While it’s been steadily falling back down the charts, it does remain a popular choice. Currently given to nearly 4000 girls in the US each year, it ranks highly in New Zealand and Canada too. In the UK, it has made significant gains, becoming familiar for girls – and for boys too. 
Borrowed from an English surname, meaning “son of Adam,” Addison joined Madison as one of the few “son of” names to be used almost exclusively on girls. It also joins the 17 strong crowd of “Ad- names” in the charts for girls, including Adeline, Adelyn, and Adelaide. 
Contemporary and cool with a cute, sassy nickname, Addison has been a popular choice for celebrities. Baseball player Jason Bay, TV personality DeAnna Papas Stagliano, NASCAR driver Sam Hornish Jr, and Joe and Kendra Duggar all have daughters called Addison. 
It is unclear if Addison will fall as fast as it rose, but for now it remains comfortably within the Top 100. So, if love Addison but want your choice to stand out, you could try: Sullivan “Sunny”; Halliday “Hallie”; Barrett “Betty”; or Alcott “Lottie.”

Adelaide is now heading straight uphill on the coattails of such newly popular sisters as Ava, Ada, and Audrey, and in the company of Adeline and Amelia. It was chosen by actress Katherine Heigl for the name of her second daughter.
 Adelaide gained fame as the noble German princess who married the British King William IV in 1830 and became known as "Good Queen Adelaide," inspiring the name of the Australian city and a craze for her name. Earlier, St. Adelaide was married to Otto the Great and became Empress of the Holy Roman Empire, described as "a marvel of beauty and goodness."
 When Aussie actress Rachel Griffiths (also mother of son Banjo) chose Adelaide for her daughter, she said she'd been inspired by the city, Miss Adelaide in Guys and Dolls, and the Disney character in The Aristocats. Adelaide can also be found in works by Thomas Hardy and Agatha Christie.

Alyssa was in the Top 20 from 1997-2010 and peaked as the 11th most <a href="https://nameberry.com/girls-names">popular girls’ name</a> in 1998 and 1999 but has become less popular in recent years. It's related to the flower alyssum as well as to the classic Alice and variants. Alyssa Milano helped give it a bounce back when she was still a child sitcom star.

Archie made global news as the surprise first name of the newborn royal baby, son of the Duke and Duchess of Sussex aka Harry and Meghan. Archie has now officially transcended Archie Bunker and Riverdale's Archie to take the, um, throne as the quintessential retro nickname name. 

Though Archie dropped from the Top 1000 in the US in the late 80s because of Archie Bunker's negative image, it's been in the British Top 100 since the beginning of this century. Thanks to its new royal status, we expect Archie to rise again in the US too.

Funny couple Amy Poehler and Will Arnett for their son--though they did put the full name Archibald on the birth certificate.
 Archie can be a female nickname name too--Archie Panjabi, who won an Emmy for her role as Kalinda Sharma in "The Good Wife" in 2010, was born Archana.

Archie

Austin is one of the most attractive <a href="https://nameberry.com/list/572/names-for-city-babies">city names for babies</a>, with an appealing southwestern feel and place-name panache.
 Austin has been an Anglo-Saxon surname and a first name since medieval times. Austin reached the Top 10 in the 1990s, but in 2022 slipped out of the US Top 100 for boys. 
 Literary namesakes include Austin Sloper in Henry James' novel Washington Square, and there have been several Austins in soap operas and films.
 The Austen spelling is also used fairly evenly for boys and girls, sometimes as an homage to Jane Austen.

Bright, fresh, and sunny, Ayla is a fashionable choice for girls. Reminiscent of other trending names such as Layla, Isla, and Ava, Ayla has recently found its place in the Top 100. 
At first glance, Ayla appears to be short, sweet, and simple – a modern invention, perhaps – but don’t be deceived. Like many names, it has different pronunciations and various origins, making it an exciting and international choice. 
In Turkish, Ayla is pronounced “Eye-luh”, meaning “halo” or “moonlight,” whereas in Hebrew, it could be a modern take on the Biblical “Elah” meaning “terebinth tree,” from “Alon” meaning “oak tree”, or, from “Ayelet” or “Ayala” meaning “doe, deer, gazelle.” 
Alternatively, Ayla is a literary name, created by Jean. M. Auel, for her novel Clan of the Cave Bear.” Pronounced “Ay-luh,” the independent heroine inspired American parents to use the name, and following the release of the film adaptation in 1986, it leapt straight into the Top 600. 
Internationally popular, Ayla ranks highly in the UK, Sweden and Azerbaijan, and is on the rise in France and Belgium. 
 In the US, over 2500 girls are given the name each year, meaning it has more than doubled in usage over the last decade. 
Notable namesakes include the American singer, Ayla Brown and the Turkish politician and activist, Ayla Akat Ata. A popular choice among influencers too, “The Flo Fam”, “Sunkissed Mama,”, and “The Prince Family” all have daughters called Ayla. 
As lovely as the name is, in its own right and as an alternative to a Top 10 choice, it may be worth keeping in mind how similar Ayla’s sounds are to those high-ranking names. This couldlead to confusion between Ava/Isla/Ayla, or to Ayla feeling more popular than it actually is. 
If you do love Ayla but want to stand out from the crowd a little more, you could consider Mira, Eira, Liora, Alara, Miray, or Aviya for their similarity in sound or feel.

Ayla

Cole -- a short name that embodies a lot of richness and depth -- has long been associated with the great songwriter Cole Porter. It's quite popular in Scotland.
 Old King Cole -- which refers to a real British king -- is familiar to all kids. Cole was the name of the child in The Sixth Sense and was also the name of -- sorry -- the notorious outlaw Cole Younger, who was born Thomas Coleman.

Cole

The Top 10 boys' name Elijah is derived from the Hebrew name Eliyahu, composed of the elements ’el and yah, both of which refer to God. In the Old Testament, Elijah was the prophet who went to heaven in a chariot of fire, a story sure to inspire any young Elijah.
 Like many biblical patriarch names, Elijah was on a long downward slide from the 19th century until the late 1960s, when it reversed course and headed uphill. Elijah was rejuvenated when Cher and Greg Allman bestowed it on their son Elijah Blue in 1976, and got another shot of youth serum via young actor Elijah Wood.
 Among other celebrities who have chosen Elijah for their boys are Donnie Wahlberg, James Spader, Tracy Nelson, Wynonna Judd and Bono (who followed it with <a href="https://nameberry.com/list/673/middle-names">middle names</a> Bob Patricus Guggi G.).
 Elijah figures in the Jewish, Christian and Muslim religions. There are numerous songs containing the name, and Elijah is also a character in many films and books—including Charles Dickens's Martin Chuzzlewit.
 Elias is the related, Greek variation of Elijah, also quite popular. Eli is a separate, unrelated name, though sometimes used as a short form of both Elijah and Elias.

Elijah

Emilia is the feminine form of the Roman clan name Aemilius, which derived from the Latin aemulus, meaning "rival." In Shakespeare’s Othello, Emilia is the wife of Iago and confidante of Desdemona. Amelia, although homonymous, has a different root and meaning. 
 
Emilia is rising as an Emily/Amelia alternative. In modern pop culture, Emilia is the name of the main character in The Princess Diaries and the first name of Game of Thrones and Solo star Emilia Clarke.
 Emilia is currently enjoying high popularity across some diverse cultures—it's near the top of the charts in Germany, Finland, Austria, Poland and Chile, and is favored in both English- and Spanish-speaking countries.

Emilia

Everett is a preppy but outdoorsy name, with wintery New England vibes. In the last decade, it’s had a leap in popularity, perhaps because of its similarity to trendy girls’ names like Ava and Scarlett, or perhaps because it offers a fresh alternative to 90’s style Evan and Brett. 
 
Despite its sleek, sharp sounds, Everett’s meaning lends it some rugged charm. An English variation of the German Eberhard, it means “brave as a wild boar”.
 
George Clooney and Dermot Mulroney drew attention to the name when they played Everetts on screen back in the 2000s. More recently, Everett Ross from Marvel’s Black Panther, and Everett Acker from the television series Breaking Badshone a spotlight back on the name. 
 
Everett feels fresh and contemporary, fitting into the trend of surnames-as-given-names and getting cool points from its fashionable V sound. But it also a name with a history. It ranked in the US Top 100 at the beginning of the 20th century, offering it a sense of solidity. 
 
Now, it’s revived and more loved than ever, with 4000 parents choosing it for their sons each year. Gentle but sophisticated, wild but refined, Everett could become an even more poplar choice in the future. 
 
If the sound of Everett appeals to you but the popularity doesn’t, you could consider Barrett, Truett, Beckett, Merritt, or Garnett. If its style intrigues you but you want something more unique perhaps Everest, Wilder, Patton, Roscoe, or Huxley could be a place to start.

Everett

Grayson, which you might think of as a Jason-Mason substitute, has been rising through the US Top 1000 since 1984 and has ranked in the Top 100 since 2011. 

That makes Grayson a modern classic boys' name, with both a sober buttoned-up feel as well as an unconventional masculine vibe. Grayson might plausibly be a banker or an artist, and its resemblance to its female counterpart Grace gives it a feminist gloss.
 
Grayson's biggest problem, if you consider it one, is its persistent, widespread popularity. The Greyson spelling also ranks highly in the US and throughout the English-speaking world, and a wide range of alternative spellings including Gracen, Gracyn, and Greysun have sprung up for baby girls and boys.
 
Last year, about 11,000 baby boys in the US were named Grayson and Greyson alone, as many s were named William or Henry, making it a solidly Top 10 name.

Grayson

You might think of Harper as the hottest name of the last decade, jumping from obscurity to the Top 10, where it remained until last year.
 
Victoria and David Beckham's choice of Harper for their youngest child and only daughter in 2011 did much to catapult the name to stardom. Some reports say Harper was named after a character on Disney's Wizards of Waverly Place, her brother's favorite show, while other say she was named after Harper Lee, author of To Kill A Mockingbird, her mom's favorite book.
 
Those two influences definitely helped propel Harper up the popularity list in general. Plus Harper is a member of the trendy group of occupational surnames turned first names for both genders, including Taylor, Parker, Mason, and Skylar.
 
Harper has been a shooting star in the celebrisphere, chosen first by Ali Wentworth and George Stephanopoulis, followed by Lisa Marie Presley, David Spade, Dave Grohl, Martie Maguire, Tiffani Thiessen, Bill Hader and Neil Patrick Harris. Singer Paul Simon used it for his son more than 50 years ago.
 
While Harper was used near-exclusively for boys in the 1800s and remains technically unisex, in reality it's used today overwhelmingly for girls. More than 8000 baby girls were named Harper in the US last year, versus only 138 baby boys.

Harper

Harvey, which was brought to England by the Normans and is a version of the French name Herve, is a genial, old-timey name that has been much more popular across the pond. It has been a Top 100 choice in England & Wales since 1997.

 In the US, Harvey is an under-the-radar classic which currently sits just below the Top 400. It has been climbing steadily since the early 2000s, with only a slight dip following two of the biggest bad-news stories of 2017, the Hurricane Harvey and convicted sexual offender Harvey Weinstein. Since then, the name has bounced back – a tribute to Harvey's classic charm.

 Harvey previously had a respectable run as a Top 100 name in the US in the late nineteenth and early decades of the twentieth century.

Harvey

Holden is a classic case of a name that jumped out of a book and onto birth certificates--though it took quite a while. Parents who loved J. D. Salinger's The Catcher in the Rye are flocking to the name of its hero, Holden Caulfield -- not coincidentally in tune with the Hudson-Hayden-Colton field of names. (Trivia note: Salinger supposedly came up with the name while looking at a movie poster promoting a film starring William Holden and Joan Caulfield, though other sources say he was named after Salinger's friend Holden Bowler.) Another impetus was provided by a soap opera character introduced in 1985.
 Among the celebs who have chosen Holden are Brendan Fraser and Mira Sorvino.
 In Australia, only a car-lover would choose this name, which is inextricably linked with the car-brand.

Holden

Hunter has been dropping a bit for the past few years but is still one of the leaders of a distinctive band of boys' names that combines macho imagery (Hunter, Austin, Harley) with a softened masculinity. Hunter was for years attached to gonzo journalist Hunter S. Thompson; Josh Holloway used it for his son.

Indiana is one of those place-names (think Camden and Trenton) that sounds cooler than the place that inspired it. Its fashionable -ana ending certainly sounds eminently name-like, and Indie/Indy/Indi is one of the hottest <a href="https://nameberry.com/list/220/nicknames-for-girls">nickname names for girls</a> right now.

Indiana

Jason with a K or Kase with an N or Karson without the R. Kason is one of many similar names that are extremely popular right now.

Kayson is the most popular of the bunch, but besides Kason, there's also Kasen and Kaysen and Cason and Cayson and so on. All variation of Kason are close to Mason, Jason, Grayson, Kayden.

Kason is a strong attractive name, but one you're likely to encounter coming and going.

Kason

Popular pop name, inspired by Australian singer Kylie Minogue. It was at its height in Australia in the 1970s and early 80s; often cited as a Noongar name meaning "boomerang". 

 Kylie has also been used as a feminine form of the Scottish name Kyle. The youngest Kardashian sister, Kylie Jenner, is undoubtedly keeping its style going.

Kylie

Lila is one of the <a href="https://nameberry.com/girls-names">girl names</a> with a double l sound — Lila, Lola, Layla, Leila, Lily et al — that have caught on in a major way., Delicate yet dynamic, Lila has a slightly international flair.
 
The one caveat, and you may consider it a big: As a group, the La-La names have gotten so stylish so quickly that they're verging on full-blown trendiness and tend to blend into one another. So while there may not be another little girl named Lila in town, between those named Lillian, Lily, Layla, and so on, you may feel there's a double L overload.
 
Lila was derived from the Arabic word laylah, meaning "night." It has separate roots in Sanskrit with the meaning "play." In Hinduism, Lila is a conceptualism of the universe as a playground of the gods. Lilah and Lyla are variant spellings. 
Lila has been a recent hot TV character name, seen on such shows asDamages and Dexter, as well as Friday Night Lights, where the name is spelled Lyla—another trendy version.
 Trivia tidbit: Diane Sawyer was born Lila Diane.

Lila

Sawyer is a surname with a more relaxed and friendly feel than many others, and is one of the hottest occupational names right now, with the Nameberry seal of approval. Sawyer is becoming one of the <a href="https://nameberry.com/unisex-names">top unisex names</a>. Both Sara Gilbert and Diane Farr used Sawyer for their daughters, while it was given a boost as a boys' name by the character Sawyer on Lost, an alias for the character really named James Ford. 
 Kate Capshaw and Steven Spielberg were among the first to discover Sawyer when they used it for their son in 1992, the year it leaped up 356 places. 
 Sawyer is a relatively common surname--think Tom and Diane. It originated as an occupational name for a woodcutter, otherwise known as someone who worked with a saw.

Sawyer

Sienna has been a Top 100 choice in England & Wales since 2005, the year after Sienna Miller's acting breakthrough in the hit movies Alfie and Layer Cake. In the US, it also got a big boost in the early noughties, before dropping slightly then rebounding to reach an all-time high in 2022.

 Now the name Sienna has gotten maybe its biggest boost of all when it was announced as the name of the daughter of Princess Beatrice and Edoardo Mapelli Mozzi. The royal baby, born in 2021, is named Sienna Elizabeth. Cable newsperson Campbell Brown also chose Sienna for her daughter, as did Kevin James. 
 
The historic Tuscan city is spelled Siena, but the Sienna spelling is the one used recently by Princess Beatrice for her daughter. Sienna, also the spelling used by American-born English actress Miller, is more popular than Siena in the English-speaking world. 


 The city of Siena is said to have been founded by Senius and Aschius, two sons of Remus. The name of the city may derive from Senius, although other possibilities include Roman or Etruscan family names, a Gaulish tribe name, or a Latin root meaning "old". 

 The English color word "sienna" ultimately comes from the name of the iron-rich clay in the Italian city, brownish yellow when raw and reddish brown when burnt, making this a vibrant color name as well as a romantic place name.

Sienna

Skyla is the most feminine form of the Skylar / Sklyer trend - little Skyla will never be mistaken on paper for a boy.

Skyla

Vanessa was invented by writer Jonathan Swift for a lover named Esther Vanhomrigh—he combined the first syllable of her last name with the initial syllable of her first. Swift used it in the poem Cadenus and Vanessa in 1713. A century later, Johan Christian Fabricius used Vanessa as the name of a genus of butterfly.
 
Vanessa was one of the ultra-feminine three-syllable hits of the eighties, but has proved to have had more staying power than others like Tiffany, Kimberly, and Melissa, due to its classic beauty.
 Vanessa Redgrave is the doyenne of the renowned Redgrave family; Vanessa Hudgens, the young actor and singer from High School Musical is a more youthful bearer. On TV there have been Vanessas on The Cosby Show, Gossip Girl and Vampire Diaries.

Vanessa

The name Veronica projects a triple-threat image: at once saintly, sensuous, and strong. The name derives from Berenice, the Latin form of the Greek name Berenike "she who brings victory", with the spelling influenced by the Latin phrase vera icon "true image". Veronica was the name of the compassionate woman who wiped Jesus's face when he was on his way to Calvary and whose cloth was miraculously imprinted with his image: she is now the patron saint of photographers.
 Then there was Veronica (born Constance) Lake, the peekaboo blonde of the 1940s, and the sultry, dark-haired rival of Betty in the Archie comics. And, more recently, we've had tough teen private eye, Veronica Mars. Veronica is also the name of an herb with small, bright blue flowers.
 Veronica was in the Top 100 from 1972 to 1991, but it might not be too soon for a comeback—sans the dated nickname Ronnie, although hit CW show Riverdale, loosely based on the aforementioned Archie comics, may provide a boost.

Veronica

Viola has several positive elements going for it: the rhythm of the musical instrument, the association with the flower, the trending 'Vi' beginning and its leading role in Shakespeare's Twelfth Night. 
 In the Bard's gender-bending comedy of identity and disguise, Viola is the appealing, passionate heroine. Later takes on this tale include Shakespeare in Love, with Gwyneth Paltrow as Viola de Lesseps and She's the Man starring Amanda Bynes.
 The most distinguished current bearer is Oscar- and Emmy-winning actress Viola Davis.
 Viola was a Top 50 name from 1899 to 1911, falling off the list in 1972, but is still popular in other countries such as Italy, where it is Number 15. And with Violet not sounding quite as fresh as it did, the strong Viola could find herself back in the running.

Viola

An ancient tree that figures in literature from Shakespeare to Harry Potter and is believed to possess magical powers, Willow is a lovely name, as graceful as its inspiration.
 Willow's use as a given name derives directly from the willow tree, whose name was derived from the Old English word welig, meaning "willow." Willow trees are associated with grace and elegance, which gave way to the adjective "willowy." Other names with meanings related to willows include Arava, Willoughby, Dozier, Wellesley, Selby, and Salton.
 
This elegant and charming nature name has been chosen for their daughters by Will Smith and Jada Pinkett Smith, Michelle Monaghan and Pink. It's been a fast riser in recent years, climbing along with other Will names Willa, William and Will, having taken off here a year after the character of Willow was introduced on Buffy the Vampire Slayer in 1997.
 
Willow is also popular in other English-speaking countries: Australia and the UK, Canada, Ireland, and Scotland.
 
The name has transcended its one-time hippie aura to move into the realm of reappraised and appreciated <a href="https://nameberry.com/list/329/nature-baby-names">nature names</a>. The willow is believed by the Romani to possess the ability to heal the sick and rejuvenate the aged.
 
Pink was quoted as saying her choice was influenced by a willow tree she grew up near, and that it is the most flexible tree that nothing can break—no wind, no elements, it can bend and withstand anything.
