Historically a diminutive of Wilhelmina, Elma's parent name and soundalike sisters are slowly stirring back to life as the trend for vintage baby names continues.

Santana is a saintly name...or Latin rock band. While traditionally masculine, character Santana Lopez on the show Glee showed the name's potential for a girl as well. Sound-wise, it feels like Savannah with a twist.
