Brother or sister for Isla J

No longer tied to the hapless Ace Ventura, this jaunty, high-flying nickname name is starting to take flight among celebrity and other parents, with its countless positive references to doing well in tests and poker games, on the tennis court and golf course, and in the air.

Adelaide is now heading straight uphill on the coattails of such newly popular sisters as Ava, Ada, and Audrey, and in the company of Adeline and Amelia. It was chosen by actress Katherine Heigl for the name of her second daughter.

While theoretically unisex, this surname name has been edging up the girls’ names list, perhaps originally as an Ashley substitute. One quality in Ainsley's favor: It's remained steadily popular -- but not TOO popular -- for more than 20 years now, ranking consistently around Number 400. That makes it stylish and familiar without showing up everywhere.

Arden is a gender-neutral name that's sleek and stylish but always seems to bob just below the surface of popularity, despite ticking all the boxes with its fashionable two-syllable, N-ending shape and its awesome nature-inspired meanings. In the 2021 US statistics, 41 percent of the babies named Arden were boys to 59 percent girls.

This name of the Cretan goddess of fertility is most popular now as the more melodic Ariana, but Ariadne has possibilities of its own. It first entered the US Top 1000 in 2014. The renewed interest in the name falls in line with the revival of other mythological names like Apollo and Athena. The trendy nickname Ari doesn't hurt either.

Beckett is one of the big baby name hits of the decade.

Bryn is an up-and-coming gentle, yet substantial, Welsh name that would also be effective in the middle spot. In Wales it's a traditional boys' name, but it's far more popular for girls now in the US.

Callum, a charming Scottish name high on the list in England, Scotland and Northern Ireland, is rising through the ranks in the US now too. And it comes complete with the easy nickname Cal.

Cassian is a saints' and Latin clan name, related to Cassius, that is virtually unused and waiting to be discovered.

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

The lyrical and melodious Elodie, a Nameberry favorite, is starting to rise through the US popularity charts for the first time since the 1880s. It's a uncommon member of the trending El- family of names, which includes Ella, Eloise, and Eleanor.

Elsie is a sweet vintage nickname-name turned modern star. After a 30-year hiatus, Elsie started climbing the US popularity list 20 years ago and is still headed for the top.

Grayson, which you might think of as a Jason-Mason substitute, has been rising through the US Top 1000 since 1984 and has ranked in the Top 100 since 2011.

Hemingway readers will recognize this as the name of Papa's first wife (and, eventually, actress Mariel's grandmother). But in Victorian times, Hadley and Hedley were actually more popular for boys.

You can ride one, you can use it as a baby name – or, as is often the case, both! Harley is currently trending up for girls and down for boys in the US, although it remains predominantly masculine in the UK. A lesser-used -ley ending choice for boys, Harley has a current sound but an old-school biker appeal.

Huxley is definitely rising as a surname name, with its X that makes almost any name cooler. It debuted in the US Top 1000 in 2015. The modern nicknames Hux and Huck certainly don't hurt.

Though it sounds like a modern invention, Kiran is a traditional Hindu name from India; chosen for her son by actress Kelli Williams. Author Kiran Desai is a woman and this name, which bears a resemblance to both the Irish (male) Kieran and the fifties favorite Karen, certainly works as well for a girl.

Though greatly overshadowed by the trendy Olivia, Olive has a quiet, subtle appeal of its own -- and is now enjoying a remarkable comeback. Olive is one of only four girl names starting with O on the US Top 1000. Cool couple Isla Fisher and Sacha Baron Cohen chose it for their daughter, reviving the name to stylishness, and now Drew Barrymore has a little Olive too, as has country singer Jake Owen.
