I immediately think of
Oswald the
Lucky Rabbit,
Walt Disney's first big animated character (he had the rights snatched from him so well that the Disney company didn't win all of them back until just a few years ago). It's not a bad association; I'm just into cartoon history, so it's where my mind goes first.
I don't really like
Oswald myself, though
Ozzie is a neat nickname. I could see it working, though I think I'd prefer it in the middle name slot. The sounds are quite unfashionable, so be prepared to hear a lot of "Ew!"ing from people around you who don't realize that it's a family name. ;)
