Lucia is a lush, rich Latinate equivalent of Lucy, popular in Spain and throughout Latin America and also a cross-cultural favorite. You might be surprised to know that Lucia has ALWAYS ranked among the Top 1000 girl names in the US, though she's really taken off only since the turn of this century.

Lilith is derived from the Akkadian word lilitu meaning "of the night." In Jewish folklore she is portrayed as Adam's rejected first wife, who was turned into a night demon for refusing to obey him. Lilith is unrelated to most other Lil- names, with the exception of Lilita, which is the Latvian variation.
