He might not have one. Ask people in Storybrooke questions and they just sort of say "I don't know" and don't think it's odd they don't know. If you asked Mr. Gold his first name, he probably wouldn't be able to come up with one.

Most people's names in Storybrooke are clues to their other identity. Red = Ruby... Cricket = Hopper, Rumple = Gold, Snow = Mary Margaret (mix of the fake names she gave to Red when they first met), Frankenstein = Whale (the movie was directed by James Whale). Not quite sure how they came up with David Nolan or Leroy though.
