Ashley was a sensation in the 1980s and 1990s; it hit Number 1 in 1991. Ashley is still pretty but more and more parents are turning to newer names like Ashlyn and Aubrey, and spellings such as Ashleigh and Ashlea.  If you hear the name Ashley in a playground today, it's more likely to be the mom than the little girl.

Ashley

Hot star Ashton Kutcher is pushing this unisex choice toward the boys' camp, but its variation Ashtyn is on the rise. 

Ashton

Though associated traditionally (and fashionably) with boys, it has been used occasionally for girls as well – by Garth Brooks, Nicolas Cage, and Facebook founder Mark Zuckerberg, for example. But August is used significantly more often for girls these days than traditional feminine variations Augusta and Augustina, and makes for a fresh twist on traditional month names like April and May, as well as an updated spin on season name Autumn.

August

Parents who love the great English novelist Jane Austen may choose this spelling of the popular name Austin to honor the author of Emma and Pride and Prejudice.

Billie

The unisex Blake, which indeed has two conflicting meanings, has a briskly efficient image when used for a girl. 
 Though in the eighties it was seen very much as a <a href="https://nameberry.com/boys-names">boys’ name</a>, epitomized by the character of Blake Carrington, the silver-haired, powerful patriarch of the TV soap Dynasty, these days it's more apt to be associated with Blake Lively, the attractive lead of the Gossip Girl series and the film Sisterhood of the Traveling Pants.

Blake

This friendly Irish surname is catching on with girls, perhaps due to the easy Callie nickname.

Callahan

Best known as one of the moons of Jupiter, Callisto was a nymph coveted by Zeus who was turned into a bear by Hera, becoming the Great Bear (Ursa Major) constellation.

With its friendly, sensitive, and approachable feel, Cameron is a 90’s favorite that remains popular today. It has a pleasing balance of soft and strong sounds, and holds unisex appeal, thanks to Cameron Diaz. Still, ten times more boys than girls are named Cameron in the US. 
Derived from a Scottish surname which in turn comes from the name of a West Highland Clan, Cameron means “crooked nose” in Gaelic. 
Not the best of meanings, perhaps, but it is likely to have originated from a nickname given to an 8th century member of the clan. Such nicknames were common in Highland culture, and it lends the name a rugged, outdoorsy feel. 
Used sporadically in the early half of the 20th century, Cameron became a popular choice in Scotland from the 50’s onwards. Shortly afterward, it began to accelerate up the US charts, really taking off in the 90’s, and peaking at #31 in the year 2000. 
Its popularity spread to Australia, England and Wales, Canada, and to France too, where it remained a top choice into the early 2010’s. Since then, it has been on a mostly downwards trajectory, though it is still given to 5000 boys – and 600 girls – in the US every year. 
Many will associate it with Cameron Frye, the anxious, slightly awkward, but good-hearted best friend in the movie Ferris Bueller’s Day Off. Actress Cameron Diaz is another memorable namesake, whose fame popularized Cameron as an option for girls too. 
A favorite in the sporting world, the name is worn by American footballer Cameron Jerell Newton, tennis player Cameron Norrie, and Olympic swimmer Cameron McEvoy, just to list a few. 
These sporty associations help to give Cameron an energetic vibe to complements its soft and calmer sounds, giving it a more “all-rounder” feel. 
Enjoy Cameron, but feeling put off by its meaning or popularity? You could try Camden, Caspian, Callum, Callahan, Cormack, or Cambell instead.

Cameron

Charlie is one of the friendly, tomboyish male nickname names--another is Sam-- now used almost as frequently for girls: in 2015, it ranked higher on the girls list than on the boys list for the first time.

Jeremy Sisto has a hyphenated Charlie-Ballerina. And as Charlotte gets more popular, there will only be more little girl Charlies.

One of the new bird names, like Lark and Wren, this one's associated with the billing and cooing sounds of love. Soft and gentle, Dove also has the admirable association with peace.

 One admirable surname association is with Rita Dove, the Pulitzer Prize winning poet and former United States Poet Laureate.

While this has a distinguished male namesake -- astronomer Edmund Halley and his comet -- it still strays too close to the superpopular feminine Hailey family to work for some parents for a boy.
