Alison has been long popular in Scotland and widely used here since the fifties. This more feminine medieval elaboration of Alice had long surpassed the original in popularity, but now sounds a tad dated in the U.S., with Alice having leapfrogged back over Alison, Allison, Alicia and other variations. 

Last year, about 650 baby girls were named Alison in the US, versus four times that many called Allison and five times that number, about 3300, named Alice.

Arden is a gender-neutral name that's sleek and stylish but always seems to bob just below the surface of popularity, despite ticking all the boxes with its fashionable two-syllable, N-ending shape and its awesome nature-inspired meanings. In the 2021 US statistics, 41 percent of the babies named Arden were boys to 59 percent girls.

 A locational surname name deriving from several places in England, there are multiple legitimate derivations for this name. One is from Old English earn "eagle" + denu "valley", while another is from the Celtic ard meaning "high".

 For literature lovers: Arden is the name of the magical forest in Shakespeare's As You Like It (Shakespeare's mother's name was Mary Arden), and it also appears in the name and titular character of a poem by Tennyson, Enoch Arden.

Though most parents would shy away from Ebenezer, short form Eben is affable and creative and perfectly able to stand alone; nothing Scroogish about it. This also makes a fresh new spin on the very popular Ethan or Evan.
 Eben Oleson is the name of the character played by Josh Hartnett in the movie "30 Days of Night."

Eben

While Elliott and Elliot are well-established for boys, parents are now considering both these <a href="https://nameberry.com/list/79/boy-names-for-girls">boy names for girls</a>, too. 
 
Credit the possibility of nickname Ellie, as well as literary associations with writer George Eliot - born Mary Ann Evans.

Elliott

Fallon was one of the first of the unisex surname names, but thanks to "Dynasty" in the 1980s it now has a feminine image.  For a boy, try Phelan instead. 

Fallon

Finn is a name with enormous energy and charm, that of the greatest hero of Irish mythology, Finn MacCool (aka Fionn mac Cuumhaill), an intrepid warrior with mystical supernatural powers, noted as well for his wisdom and generosity. 
 Finn was chosen by cool couple Christy Turlington and Ed Burns for their son, and also by Jane Leeves and Autumn Reeser. Played by Cory Monteith prior to his death, Finn Hudson was a prominent character on Glee.
Other up-and-comers in the same family: Finlay and Finley, Finian and Finnian, Finnegan and Finnigan, and, from Germany, Fynn.

Finn

Short, sharp, and cool, Jett is a contemporary choice that connotes both gemstones and jet engines. Rarely used before the 90s, John Travolta, and then George Lucas, helped to put the name on the map by choosing it for their sons. 
 
Jett is a word name with a twist, a bit like Forrest or Merritt and that extra "T" moving it more firmly into name territory. It is associated with the highly, polished black gemstone and the color "jet black", meaning it fits in with the likes of Jasper, Onyx, Scarlett, and Jade. It is also associated with jet engines, jet planes, and speed and it was this connection that likely drew aviation enthusiast Travolta to the name - though it could work for someone wanting to honor their love for travel too.
 
For those wanting a less wordy association, you could link Jett to the surname Jetson, which is a diminutive of Jordan, via the old pet forms Jutt and Jud. 
 
Jett first entered the US Top 1000 in 1999 and climbed steadily until 2009 when it was one of the fastest rising names of the year. Since then it has returned to travelling steadily upwards, and is now in the Top 300. Given to over 1700 babies every year, it is also moving up the charts in the UK.

Jett

Though it sounds like a modern invention, Kiran is a traditional Hindu name from India; chosen for her son by actress Kelli Williams.  Author Kiran Desai is a woman and this name, which bears a resemblance to both the Irish (male) Kieran and the fifties favorite Karen, certainly works as well for a girl.

Kiran

A kind of old-fashioned nickname name that's enjoying some fresh life thanks to trendy brother Lane.  Lainie is a more old-school spelling.

Laney

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

A Top 100 name from 1896 to 1921, Leona reached as high as Number 72.
Since then, Leona had seemed to be one of the most unfashionable of the pride of lion names, but singer Leona Lewis has done a lot to rejuvenate it.

Leona returned to the Top 1000 in 2009 after decades of being away. 
 A somewhat more sophisticated option is the French Leontine.

Leona

Perky, pretty nickname name that seems to have been invented by or for Marlo Thomas, who was born Margaret. Hipster mommy blogger Dooce named her newborn daughter Marlo Iris and comedian Rob Corddry named his daughter Marlo Stevenson.

Marlo

With the success of all names Max, from Max itself to Maxwell to Maxfield to Maximilian, it's just possible that Maxine could be lured away from her mah-jongg game at the clubhouse and into the nursery. She's already been chosen by hip musician Nick Hexum for his daughter, sister to Echo.
 Maxine was a Top 100 name from 1915 to 1930, attached to such celebs at the time as actress Maxine Elliott and one of the singing Andrews Sisters, and now to Congresswoman Maxine Waters and Chinese-born writer Maxine Hong Kingston. Reentered the US Top 1000 after a two decade absence in 2016.

Maxine

Miles, which has a permanent veneer of cool thanks to jazz great Miles Davis, is a confident and polished boys' name that's an American classic. Always ranking in the US Top 1000, it's been drifting up the charts for the past half century but has never been TOO popular.
 
Miles is a favorite of celebrity baby namers, given to their sons by Elisabeth Shue, Mayim Bialik, Larenz Tate, Joan Cusack and Lionel Ritchie. It also makes a great honor name for all the Grandpa Michaels out there.
 Miles was the name of the first translator of the Bible into English--the English monk Miles Coverdale, which is also the name of a character in Hawthorne's The Blithedale Romance. Miles Hendon figures in Mark Twain's The Prince and the Pauper, and Miles was one of the young children in Henry James's The Turn of the Screw. Miles--or Myles--Standish was the leader of the Pilgrim fathers.
 Miles has also been a favorite movie and TV character name from the days of Murphy Brown to 24 and Avatar.

Miles

This name owes its present life to actress Sorvino. Mira and Mirra have an arty aura. 
 
Mira is a true cross-cultural choice, with the literal meaning of "look" in Spanish, a peaceful meaning in several Eastern European languages, a well-used name in Arabic cultures meaning queen-like or a female ruler, and a nature name in Sanksrit. In Greek, it means "fate, destiny". 
 
Mira can also be a short form of Miryam or Miranda.

Mira

Among a small shower of rain-related names, this pure version can have a cool, refreshing image. 
 Richard Pryor named his now-grown daughter Rain, and Rain is also one of the nature-named Phoenix family siblings. More recently, 24 actress Marisol Nichols named her daughter Rain India.
 Rain also makes a nice nature middle name--Brooke Burke called her daughter Heaven Rain.
 If you want to embellish this simply spelling (and alter the meaning), you might also consider Raine, Raina, Rainn, Rayne, Reine or Reign, the middle name of Willow Smith. Or you could take the Holly Madison route all the way to Rainbow.

Rain

Bird name Raven, once a symbol of pride for both African-American and Wiccan parents, is finding new life as a superhero name. Raven Darkholme is the real name of Mystique, heroine of the X-Men films played by Jennifer Lawrence. And there is another Raven superheroine in Teen Titans. Some parents may still choose Raven to signal black pride or mystical powers or maybe even Edgar Allan Poe fandom, but we are guessing most inspiration is coming from the comics.

Raven

River shares the tranquil feeling of all the water names, and seems to have pretty much escaped its past strong association with River Phoenix and his unfortunate fate. Actor Joaquin Phoenix named his son with actress Rooney Mara after his brother River.

River's popularity is rising for boy genders, but it's still predominantly given to baby boys. Last year nearly 3500 boys were named River vs. about 1900 baby girls.

Keri Russell and the Taylor Hansons both have sons named River, Natasha Henstridge used it as the middle name of her boy Tristan, and Jason Schwartzman pluralized it for daughter Marlowe Rivers.

River

Spelling variations abound when a name is trendy, which Rosalind is not these days.  We say leave Roslyn back in the middle of the 20th century and reclaim the original Rosalind.

Roslyn

With vintage names on the rise and recent data suggesting that the US is following the UK trend of nicknames-as-given-names, Ruthie joined Goldie, Daisy, and Nellie on the US Top 1000 list in 2023.
 
A Hebrew diminutive name, meaning "compassionate friend", Ruthie softens the blunter sounds of Ruth, and is reminiscent of the popular Ruby. It was used throughout the early 20th century and peaked in the 1930s - and, if the 100 Year Rule is to be trusted, it may well continue to rise up the charts.
 
While most parents are still opting to put Ruth on the birth certificate, Ruthie was used on nearly 300 babies in 2023.

Ruthie

Less popular than the Bueller-inspired Sloane but following on its coattails, this name ranks toward the middle of the Top 1000, but we see both spellings sticking around for years to come.

Sloan

Stevie survives as a short form of Stephanie thanks to the immortal Ms. Nicks. After a little more than a decade out of the limelight, she rejoined the US Top 1000 in 2014.
 
Schitt's Creek character Stevie Budd propelled the name into the Top 300 in the late 2010s.

Stevie

Wren, a lilting songbird name, could be the next Robin. Wren entered the Top 1000 for the first time in 2012 and is among the new wave of popular <a href="https://nameberry.com/baby-names/501/english-names-for-girls">English names for girls</a>.
 Wren makes a particularly pleasing middle name choice, as does her newly discovered cousin Lark. But it's more popular as a middle name than you might think, the quirkier cousin of Rose.
 This petite bird was regarded in Ireland as the "magician of the birds" and the Druids considered it a bird of prophecy. Thanks to an early fable, it has also been known as King of the Birds.
 For architects there's the link to the great Sir Christopher Wren, the celebrated eighteenth century designer of London's St. Paul's Cathedral.
