Belle
Belle has nothing but positive associations, from "belle of the ball" to "Southern belle" to the heroine of Disney's Beauty and the Beast. Though it has been overshadowed by the Twilight-influenced Bella and longer forms like Isabella and Anabella, Belle has its own Southern charm and would make a pretty choice as a first or middle name. Belle was a Top 100 name in the 1880s, but left the list in 1934. Its most famous bearer was the legendary Western outlaw, Belle Starr (born Myra).
