The combination of Emily and Emma's popularity -- and the fact that Desperate Housewives star Teri Hatcher's daughter is named Emerson -- have put this formerly strictly boys’ name, embodying the gravitas of Ralph Waldo Emerson, in the limelight for girls.

Emmeline is an Emma relative and Emily cousin that is destined for greater use in the wake of the megapopularity of those two names. A recommended Nameberry fave, Emmeline hopped onto the US Top 1000 in 2014 for the first time ever. While it is genuinely an old name, it was rarely used a century ago; only 17 baby girls were named Emmeline in 1915, the same number as were named Ernie!

Sweet and stylish, with a sporty, energetic undertone, Everly is a name that ticks lots of boxes.

Gwendolen, an ancient Welsh favorite, retired decades ago in favor of the short form Gwen, but now, as in the case all across the naming board, the nickname has faded and the more distinguished original is up for reappraisal.

Once a macho biker name, Harley is now showing its softer side. In the UK, Harley is predominantly masculine, but it's currently more popular for girls than boys in the US.

Kaylin is a variation of Kayla and Katelyn that had several years of chart climbing before reaching a peak of Number 372 in 2009. Cailin and Kailyn are two other spellings.

Vivian, once an elderly lady name, is on the rise, along with all form of girl names that mean life -- from Zoe to Eva to those who share the vivid Viv syllable. It was one of the fastest-rising names of 2023, vaulting into the Top 100.
