Almost like a fusion between vintage Audrey, bubbly Ruby, and unisex Avery, Aubrey has been a popular choice for girls since the mid 2000’s. 
Once an exclusively masculine name, Aubrey tipped towards feminine in 1974, and is now given to girls 96% of the time. 
Derived from the Old French name Auberi, a variant of Alberich, Aubrey means “elf ruler” or “elf king.” 
It was a common name for men in England during the Middle Ages and it saw a revival in the 19th century, with the artist and illustrator Aubrey Beardsley being a notable bearer. Across the pond in the US, it remained in the Top 400 for boys until the 50’s. 
Its shift into a mostly feminine name has been accredited to the release of the song “Aubrey” by the rock group Bread in 1972. Before the song was released, less than 10 girls were given the name every year, however, by 1973, it was in the Top 1000. 
David Gates, leader and music producer of the group. wrote the song after watching Breakfast at Tiffany’s, starring Audrey Hepburn, and it is likely that Aubrey stuck around due to its similarity to the cozy-but-stylish name of the actress. 
Besides the song, Aubrey might also be seen as following in the footsteps of names like Kelly, Leslie, Lindsay, and Shelby, historically masculine but used more often for girls from the 1940’s onwards. 
One of the most prominent bearers today is Aubrey Plaza, the deadpan comic actress and breakout star of the show Parks & Recreation. Child actress Aubrey Anderson-Emmons, TV Host Aubrey Miles and soccer player Aubrey Kingsbury are other notable wearers. 
In recent years, the once Top 20 name has seen a decline in popularity however, with newer entries such as Quinn, Aurora, and Emery rising to take its place. Nevertheless, Aubrey is climbing up the charts in England and Wales and is still given to 3000 babies in the US every year. 
Are you interested in Aubrey but still wanting to explore other options? You could consider Indigo, Ashby, Darby, Darcy, August, or Libby.

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.

 Calypso was the name of Jacques-Yves Cousteau's research ship--and would make a highly dramatic, musical choice.

 Dove was actually an early bird, used as a first name in the seventeenth century and in the U.S. Top 1000 through the 1890's.
 One admirable surname association is with Rita Dove, the Pulitzer Prize winning poet and former United States Poet Laureate.

Indigo is one of the most appealing and evocative of the new generation of color names. Color names have joined flower and jewel names -- in a big way -- and Indigo, a deep blue-purple dye from plants native to India, is particularly striking for both girls and boys. Indigo is the name of a character in the Ntozake Shange novel Sassafrass, Cypress & Indigo, and was used for his daughter by Lou Diamond Phillips.
 Some cultural references: The Indigo Girls are a folk duo, 'Mood Indigo' is a classic Duke Ellington jazz composition, and there is a 1970's New Age theory that Indigo children possess special, sometimes supernatural abilities.

Juniper is a fresh-feeling nature name -- it's a small evergreen shrub -- with lots of energy. A new favorite of fashionable parents, Juniper joins such other tree and shrub names as Hazel, Acacia, and Willow. 
 
Juniper has an interesting variety of associations -- it's mentioned in the Old Testament, was used in Renaissance paintings to represent chastity, has berries used to flavor gin, and Juniper is the Saint of Comedy. A male St. Juniper was a follower of St. Francis of Assisi. 
 Goodnight Moon and The Runaway Bunny author Margaret Wise Brown sometimes used the pen name of Juniper Sage. And in the Junie P. Jones kids' books, Junie's full name is Juniper Beatrice. There also have been Junipers is cartoon series (The Life and Times of Juniper Lee) and comic strips as well.
 
The name got something of a hippieish vibe via the 1969 hit Donovan song, 'Jennifer Juniper.'
 
Juniper entered the U.S. Top 1000 for the first time in 2011 and has risen to the Top 150.

This body of water runs deep; the best of a group of new possibilities that includes Bay, Ocean, River, and the more established Brook. It has received attention via the actress Lake Bell.

Okay, this is going to be confusing... 

There is a female figure in the Old Testament named Noa or Noah, whose name derives from the Hebrew No'ah, meaning "motion". The popular Biblical male name Noah (sometimes spelled as the streamlined Noa) is derived from a different Hebrew name: Noach, which means "rest, repose" – although confusingly they are often written the same in English. 

 Noa is the modern Hebrew spelling of the female name, and is very popular for girls in Israel, as well as in several European countries, including Spain, Portugal, and the Netherlands. But Noah is an established variant spelling, popularized by Noah Cyrus.

 So is a girl called Noah named after a female Biblical figure (whose name means "motion") or a male one (meaning "rest")? That's up to you! The ideal of gender neutrality means nothing belongs exclusively to one sex or the other, and that includes the spellings of Noa/Noah.

Noah

Phoenix is a New Age name symbolizing rebirth and immortality. It's also a place name, a color name, a mythological name, AND an animal name, combining several of today's hottest trends in one appealing package.

The name Phoenix is associated with an immortal bird from Greek and Egyptian mythology, which having lifted for several centuries would catch fire, then rise from its own ashes. This cycle would endlessly repeat, and therefore, Phoenix is tied to fresh starts, rejuvenation and beginning again after loss. Phoenix is also linked to the US city in Arizona, named as such because the area was abandoned when settlers found it, and it was seen as a new city born from the ruins of another. 
Statistically, Phoenix does lean slightly to the boys' side with 1200 boys receiving the name in 2023 compared to 900 girls. Nevertheless, it shares sounds with the familiar Phoebe, Beatrix, and Fiona, as well as Phillip and Felix, and so it doesn't feel out of place on any gender. 
 A celebrity favorite, Scary Spice Mel B, rugby player Mat Rogers, fashion designer John Richmond, and actress Tammin Sursok all chose Phoenix for her daughters.

Kelly Clarkson's choice of River for her newborn daughter further raised the profile of the <a href="https://nameberry.com/girls-names">name for girls</a>. Baseball great Derek Jeter and Hannah Davis used the same name as Clarkson for their daughter born in 2021, River Rose.

Derived from the Irish surname Ó Sluaghadháin, meaning "raider" or "mobilizer", Sloane shares that preppy feel of Blair, Delaney, Ellis, and Quincy.

The name of one of the most powerful Marvel superheroes — and the first major black female comic book heroine — is certainly a big one to live up to! Portrayed in the live-action X-Men movies first by Halle Berry and then by Alexandra Shipp, Storm is a mutant descended from a long line of African witch-priestesses, who can bend the weather and atmosphere to her will.
 Several high-profile parents have already braved this one, like Mötley Crüe bassist Nikki Sixx, whose daughter Storm Brieann was born in 1994. And now that Kylie Jenner has a little Stormi, we're forecasting a few more Storms on the horizon...

Fresher, brisker and, yes, cooler than Summer or Autumn or Spring, Winter is now a full-fledged female choice, especially since Nicole Richie and Joel Madden used it for daughter Harlow's middle name, and Gretchen Mol picked it as her daughter's first, as did media mogul Sean Parker. Winter continues to be the preferred spelling and has risen in popularity significantly over the past few years.
 Although Winter entered the U.S. Top 1000 in 1978, it was been used as a first name as early as the seventeenth century.
 Some interesting international words for winter: Aeneva (Cheyenne, Native American), Cole (Chinook, Native American), Hima (Sanskrit), Jara (Hindi), Saradi (Hindi), Vandi (Kashmiri), Zaya (Old Persian) and Zima (Russian, Bulgarian).
