Eeeer, I am going to try to answer the questions *I think* you ask.
First,
Renee is French. There is an Italian name
Renata, which, like
Renee, is derived from the Latin
Renatus -- born again. So:
yes,
Renee means born again
no,
Renee does not mean anything in Italian, since it is French.
Renee is the female form of
Rene, the same way fiancee is the female of fiance. Specifics of the French language - for more information consult a French grammar book.
