I think they are all usable. Personally, I think that "old people" names are adorable on little kids, and they have enough tradition in them that they grow well. I have cousins with names like
Hazel,
Atticus,
Viola,
Opal,
Daphne,
Penelope, and
Clark. I think
Maurice or
Morris (or Morus, though this might take explaining) would be a nice name on a little boy, first or middle.
