If you love it, I'd use it. I named my son
Sebastian, even though his FN and LN rythmes with "
Sebastian Bach" lol. I forsee he goes by his FN & MN when he is older :-)
Also, I read your other post with the middle name suggestions, and If you are having problems with your family accepting a name you love, you can start out telling them you are naming him/her something completely off the wall weird, and so when you actually name your child
Isadora or
Matteo they will love it because it isn't so horrible. It's worked for lots of my friends. HTH.
