Top Contenders

Brynn outshines the original Welsh Bryn in the popularity stakes. This simple, brisk name might be seen as a combination of Bree and Lynn, an androgynous-sounding choice that especially in this spelling is not truly unisex: Brynn, for boys, is not even in the Top 1000.

Chase, with its sleek and ultraprosperous aura, is redolent of the worlds of high finance and international banking. Chase has been well used during the last few decades, seen as a character on 24 and on several young-audience shows.

Colton is a trendy two-syllable choice, with the popular 'on/en' ending.

Delaney has been a popular Irish surname name for a couple of decades, projecting buoyant enthusiasm plus a feminine feel.

Hudson has risen quickly up the charts over the past 30 years, getting a lot of its style value from New York's Hudson River. That makes it a nature name and a place name that's also got the fashion gloss of New York City.

Josie is jaunty and friendly: among the most winning of all nickname names. She's been on the social security list since records began being kept.

Luke is a cool-yet-strong Biblical name with a relaxed cowboy feel, which has been on the rise since the advent of Luke Skywalker.

Maisie, a charming name long popular as a nickname for Margaret or Mary, entered the Top 1000 as itself ten years ago and continues to rise. Game of Thrones star Maisie Williams helped propel the name back into the limelight, along with the that of her character, Arya.

Mason is an occupational surname that ranked among the Top 10 name for boys throughout the 2010s, after its choice as one of the first Kardashian baby names.

One of the first generation of surname names, along with Porter and Morgan, Parker's still one of the most appealing and remains firmly in the Top 100 for boys. About three times as many boys as girls get this occupational name. The association with Charlie Parker gives Parker itself a jazzy edge, and it also has a nature-related meaning. Rosie O'Donnell has a son named Parker.

Sadie started as a nickname for Sarah, but their images couldn't be more disparate. Where Sarah is serious and sweet, Sadie is full of sass and fun.

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.

Spencer is a name that has everything: it's both distinguished sounding and accessible, dignified but Spencer Tracy-like friendly. Picked by several celebrities (a couple of times even for a girl), adding up to an enthusiastically recommended choice.

Teddy is in some ways one of those midcentury boys' nicknames -- like Jimmy or Bobby or Billy -- yet because it was never that popular, it feels timeless too. The preferred short form of Theodore these days may be Theo and of Edward may be....Edward, but Teddy can work adorably for either and grows up to Ted. And of course, let's not forget the inevitable teddy bear.

Tessa is one of those golden names that's been popular but not TOO popular for several decades now. Tessa has ranked in the Top 500 in the US since 1981 but has risen only once above Number 200.
