Sorry, sorry... This post just reminded me of that "Neveah means 'butterfly' in Slavic!" crap that gets bandied about the cra--er, less-scholarly naming boards.
Schmetterling would make a wonderful surname for a fictional character imo. But it should in no way be a given name imo, though as always it's slightly better in the middle name slot than the first. For one thing, if the kid ever went to a German-speaking country, the natives would probably laugh themselves sick over his/her "name".
