Huh? Gildor is a Wood elf? I think I remember Frodo saying, "They spoke the name of Elbereth! These are High Elves!" in the books.
What's more, the name 'Inglorion' indicates he is of the House of Finrod. Also, Gildor mentions this himself. In that case, he is definitely not a Wood elf; he is a Noldo/Vanya.
Edit: Oh wait, I think you're talking about the possibilities in the movie. Well, in that case they're probably from Lothlórien
