Unnamed List

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.

Credit the award-winning single-named British singer for taking the girls’ name Adele from a quiet semi-retirement back into currency. Adele reentered the US Top 1000 popular baby names in 2011 and has remained there ever since.

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.

This female form of the ancient Latin Aelian has an appealing sound, though kids might have a hard time handling that initial "ae" spelling. Just remember that the "ae" is pronounced "ee" (think Aesop's fables).The Annals of Aeliana is a children's fantasy series by Ryan Watters. The meaning is uncertain but is thought to derive from the Greek helios, which means sun.

A compound name with an old-fashioned ring. It only first appeared on the US Top 1000 in 2012. Annalie is a somewhat different name that is nevertheless pronounced the same.

Avery is a unisex name that is used four times as often today for girls as for boys. But while Avery's popularity is starting to soften for girls, it continues to get stronger for boys -- in keeping with our finding that gender neutral names are becoming more favored for boys than for girls.

Hayden – a formerly obscure name that's risen to huge popularity – has dipped in this year's ratings. Though Hayden is among the most distinctive of the bunch, it gets lost in the crowd of Jaidens, Bradens, Aidans, and endless variations. Associated with Hayden Christensen, of Star Wars fame.

Lila is one of the girl names with a double l sound — Lila, Lola, Layla, Leila, Lily et al — that have caught on in a major way., Delicate yet dynamic, Lila has a slightly international flair.

The Lyla spelling variation has now superseded the original Lila — the former remains on the rise while the latter is consistently falling in popularity.

Serafina is a name so lovely it's worthy of an angel. But the more stylish spelling today is Seraphina.

Siobhan is the Irish variation of Joan, which is derived from the ancient Anglo-Norman name Jehanne. In this way Siobhan is indirectly related to the name Sinead—the Irish form of Jeannette, which also derived from Jehanne—although Sinead is not a nickname for Siobhan. Siobhan was the name of several early Irish queens and was introduced to the American public by the actress Siobhan McKenna.
