I just love using the Seventh Sanctum to help me name my characters! They got everything. From Elves to Vampires, Lovecraftian names to random names from the US census.
Now that I'm writing my epic dragon fantasy story, I've been using this site to help me generate some names for my dragons and elves! But I've used this site before for common names too. Give it a try, some of the names on that site are really silly.
