Girls

Both powerful and pretty, with a melodic sound, Aaliyah joins Layla, Lila, Dana, and Farrah as a name of Arabic origin that is also popular in the English-speaking world.

Newly fashioned but familiar and with an on trend, unisex feel, Addison seems like the perfect solution for anyone who can’t decide between Madison, Adeline, and Alison.

This variation of Adele sounds somewhat more feminine than the original by virtue of the a- ending. It could join the army of popular A girls' names, especially with its tie to the recent celebrity-related success of Adele.

Adeline has a lovely, old-fashioned "Sweet Adeline" charm, but has become so popular in the US under so many spellings and variations -- with Adalynn and Adalyn also popular -- that considered together it is far more popular than it first seems. Adorable nickname Addie is also pervasive.

Adley made the Top 1000 at Number 735 in 2012 on the heels of sister name Hadley, only to vanish again in 2013. But now, with the popularity of Adelaide and Adeline, it has leaped upward and entered the Top 1000 once again. Adley feels in step with name trends of the moment, but will it survive the ages? Other such mashups have not.

Aiden/Aidan is just beginning to wander into the girls' side of the name popularity list, but it's so huge for boys in all its spellings that it will be a long time before it can be called a unisex name.

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.

Alba is quietly making a behind-the-scenes comeback, perhaps thanks to actress turned baby-product mogul Jessica Alba. Last on the Top 1000 a century ago, the name was given to nearly 200 baby girls in the US last year. Alba might be tomorrow's successor to Ava and Ella. In Spain, Alba ranks among the Top 20 girls' names. Alba is the name of a character in The Time Traveler's Wife.

Alice is a classic literary name that's both strong and sweet, ranking in the US Top 100 and popular throughout the western world. Alice is derived from the Old French name Aalis, a diminutive of Adelais that itself came from the Germanic name Adalhaidis, which is composed of the Proto-Germanic elements aþala, meaning "noble," and haidu, "kind, appearance, type."

Alicia is a Latinized variation of Alice, a name ultimately derived from the German Adalhaidis. It emerged in the 19th century, but the 20th saw many spelling evolutions for Alicia, including Alecia, Alisha, Aleesha, and Alysha. Alyssa originated as a form of Alicia.

Alma is a somewhat solemn, soulful name that had a burst of popularity a century ago, then faded into the flowered wallpaper, and is now finding its footing once more.

While the male Alva or Alvah relates directly to the minor Biblical character, the female version is more likely an Anglicized form of the Irish name Ailbhe. Best known as Thomas Edison's middle name, Alva has true unisex roots.

Amelia is one of the hottest girls' names, a successor to the megapopular Emma and Emily. Amelia, which spent several years at Number 1 in England, vaulted into the US Top 10 in 2017 and continues to rise.

A variation on Emmeline, Ameline has not experienced nearly the same level of success in the US, though it was given to five girls in 2015. Whereas Emmeline lends itself to trendy nicknames Emme and Emmy, Ameline has a clearer path to the dated Amy.

Amy and all her sisters and cousins was such a popular name that this version was among the Top 1000 girl names in the US until the mid-90s. Last year only 32 baby girls were names Amie.

While Austin is a popular boys' name, this spelling, honoring novelist Jane, nudges the name toward gender-neutral, chosen last year for 67 baby boys and 57 girls.
