I don't consider Maria a Spanish name, but Latin, which includes my other half of familia...Italiano's
Yes, James is right...it could be Italian, or it could even be Greek...the former King Constantine of Greece's wife is named 'Anna Maria'.
I don't know your last name (I am assuming that 'Latin' isn't it! hehehe *wink* ), but in Greek Orthodox churches in suburban New York you will hear lots of Irish first names with Greek last names, and vice versa. I think it is very cute and very nice for the child too to be proud of the mosaic of their Christian background.
I hope that you are all doing well....
