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.

Adeliza

Agathe

A chic and sassy French choice, popular in France but likely to be confused with the more prosaic Alex in English-speaking countries. Although sometimes used in the US as a variant spelling of Alex, the French name Alix actually derives from a medieval French form of the name Alice or Adelaide. 

 Several members of European royal family have borne this name, including Alix of France; Alix, Duchess of Brittany; and Alix of Hesse, Empress consort of Russia. More recent are Alix d'Unienville, WWII spy; Alix Kilroy, one of the first British women to become a public servant; and engineer Alix Pryde.

Antoinette

Like the French author with whom the name is most closely associated, Colette is a chic and charming name that is being rediscovered. After disappearing for nearly 30 years, Colette rejoined the Top 1000 in 2012 at Number 659 and has continued to rise since then. Dylan McDermott used it for his daughter, as did actress Constance Zimmer.
 There is an appealing animated Colette featured in the film Ratatouille.

Constance is one of the more subtle of the virtue <a href="https://nameberry.com">baby names</a>, but still has quite a prim and proper image. One impediment to its revival has been the decidedly dated nickname Connie, though modern parents might well opt for using the strong and dignified name in full.
 One of William the Conqueror's daughters was named Constance, and in Shakespeare's King John, Constance is the devoted mother of King Arthur. Constance was widely used in the seventeenth century by Puritans: Constance Hopkins was a young passenger on the Mayflower.
 The fictional Constance Billard School appears in TV's Gossip Girl, and Constance was the first name of the decidedly non-prim and proper Lady Chatterley.
 Oscar Wilde's wife was Constance, and Mozart's spouse was the German form Constanze, nicknamed Stanzi.
 Though Constance has been neglected here for a number of years, it's still ranks at Number 120 in France.
 Trivia tidbit: Constance was the birth name of 1940's peekaboo-hairdo star Veronica Lake and also, not surprisingly, Connie Britton.
