The Cool Girls

Not as popular for girls as Kylie or Kyla, but we prefer its simplicity.

Lou is usually a short form of Louise, Louisa, or Lucy in English-speaking countries, when Lou is used for girls at all. But in France and Germany, it's a fashionable choice all on its own, sure to gain even more widespread style credibility since Heidi Klum and Seal chose it for their daughter.

Introduced to the American public by actress Neve Campbell; it was her Dutch-born mother's maiden name. Neve is an interesting and fresh new possibility, one which Conan O'Brien chose for his daughter.

Piper is a bright, musical name that entered the list in 1999, one year after the debut of the TV series Charmed, which featured a Piper, and it's been a consistent riser since. Piper Kerman is the memoirist whose prison experiences provided the basis for the hit Netflix series Orange is the New Black.

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.

Rio is one of Japan's most popular girls names, constantly sitting in that country's Top 10. Of course, Rio may also stem from the Portuguese and Spanish word for river, and the Brazilian city Rio de Janeiro. A truly international name for a cosmopolitan baby!

In the US, the multicultural surname Roe is primarily associated with the landmark Supreme Court case Roe vs. Wade, which granted the federal right to abortion. It's never been popular as a given name for either sex but is seen as a nickname for names such as Monroe and Rowan.

Rory is a buoyant, spirited name for a redhead with Celtic roots. The name Rory is getting more popular overall, but for the past few years has been trending decidedly toward the boys' side -- however, it's been rising to new heights for girls in recent years.

While Sidney in this spelling has a long history as a girls' name, it fell off the Top 1000 from the early 50s until 1990. Then it reemerged as one of the newly chic androgynous names for girls, rising into the Top 300 before falling off the Top 1000 list again in 2016. Sydney is now the more fashionable form.

Yes, Spencer makes a plausible and powerful female choice these days, though still thought of as primarily for boys. Kelsey Grammer used it for his daughter in the 1980's. Spencer made its first appearance on the girls' Top 1000 in 2017.

As Meghan/Megan and Reagan/Regan show signs of wilting, along comes Teagan to take up the slack: definitely one to consider. The vast majority of American babies named Teagan are now girls. A variant spelling is Teaghan.

The name Wilder is still used more than 90 percent of the time for boys, but it's being used quietly for girls too. Along with the rest of the Wild and Wiley family, it's one of the hottest baby names starting with W. Certainly giving your child of either gender such a, ahem, wilder name is setting them up for a certain kind of character and future.
