Unnamed List

Abigail has been in for so long -- the name has ranked in the US Top 100 since the late 1980s -- it's amazing that it isn't more out by now. But Abigail's biblical and historic roots make it a fashionable classic rather than a passing fad.

Ada is one of the classic baby names for girls that is suddenly super stylish again. A favorite at the end of the nineteenth century, Ada is an alternative to the over-popular Ava. Ada is also part of the trend toward simple, old-fashioned names beginning with a vowel, like Ivy and Ella.

Distinctive, elegant, and luxurious, Adalia can be a variation of Adele, or a Hebrew name with a Biblical background. Although it is given exclusively to girls in the US, in the Bible it is masculine. The similar Adlai might be easier to wear for boys in English speaking countries, while Adalia fits in with Adeline, Amelia, and Dahlia.

Adalyn is one of a large group of Ad-beginning names for girls, which include Adeline and Adalynn and Adelaide and Addison — essentially, anything leading to the popular nickname Addie is in. Adalyn is a beautiful name, but be prepared to have to spell it out for people often. Adalyn entered the charts in 2007 and rose quickly, but has been fairly steady in the mid 100s for nearly 10 years now.

This popular form of the even-more-popular Adeline combines the trendy Ad- prefix with the equally trendy -lynn suffix. Adalynn is the second most widely-used form of this popular name next to the classic Adeline. Singer Chris Daughtry named his daughter Adalynn Rose.

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.

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.

Adeline in all its forms, including Adelyn, is rocketing up the list, but we do prefer the original to the variations. Or you might consider varying it yet further to Adelia, Adele, or Adelaide. Or lengthen it to Madeline/Madelyn.

Adira is one of those names that feels familiar without being overused. Simple but with subtle flair, Adira crosses different languages easily and could provide an alternative option tor the likes of Ava, Ariana, Adeline, and Anna.

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.

Aidan is an ancient Irish saint's name with a fire meaning that's mega popular for boys, most often spelled as Aiden. The name is occasionally used for girls, sometimes as Aidyn or Ayden, as well. Aidan was the name of a famous seventh-century Irish saint, and is related to the Irish word for fire.

Aiden in all its spelling variations is the Anglicized version of the Irish Aodhán, which was originally a pet form of the Irish name Aodh (pronounced 'ee'), who was the old Celtic god of the sun and fire. St. Aidan was a famous seventh century Irish saint, noted for his kindness and generosity and for spreading Christianity.

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.

Alana, in all its various spellings, was at one time reserved for daughters of dads named Alan, but is now much more widespread. It came into prominence via model/actress/celeb spouse Alana Hamilton Stewart.

Fashion designer surname that could make a dynamic first.

This is one surname-name that may swing decidedly to the male side, thanks to highly-visible young actor Alden Ehrenreich.
