I like it much better than
Felicia, too, though
Felicia would probably be better overall (I'm kind of worried that my Spanish relatives will butcher
Felicity). I agree with the short middle name, and I really like
Felicity Mae,
Felicity Jane, and
Felicity Claire. Funny you mentioned
Anne and
Rose; I have both of them on my list (as first names). Maybe ____
Felicity could work, too!
