Behind the Name
Behind the Name has been since 1996 wholly devoted to "the etymology and history of first names." Not just the standard English, Spanish, and French names, but Azerbaijani and Esperanto names as well. There are lists of namesakes (kings, queens, hockey players, etc.), and a clever roster of "linguistically logical" names for twins. There's also a message board, where questions can be posted about the meaning, history, and usage of given names.
