Joseph is a great name! I think of all the ubiquitous men's names, it may be my very favorite. You can't go wrong with
Joseph,
Joey, or
Joe. Both your combos are gorgeous, though I would opt for
Joseph Diego because
Amadeus is a little pretentious on a real person. Do you like
Joseph Amedeo or
Joseph Amadeo? I also like
Joseph Paschal,
Joseph Asa,
Joseph Leon,
Joseph Xavier. I think it's a great Fn to pair with an unusual Mn.
