Re: Alphonia - questions | long post (sorry)
Sorry, it does remind me of aphonia. I think it would work fine on a fictional character, but 'phonia' makes it sound too medical for a real person's name.
If you want it to be clear that it's a feminization of Alphonse I think Alphonsia, Alphonisa, Alphonisia, etc, would be better for that. Maybe it's me, but I wouldn't have assumed Alphonia was related to Alphonse.
Combos: I like Alphonia Estelle.
