My name is Lucia and I LOVE it. I changed my name to it 4 years ago :o) I started off with the "loo-sha" pronunciation just because it was the only one I'd been exposed to up until that point. I moved to Spain last year though, and so that pronunciation went out the window. I really love "lu-SEE-ah" (or in my case over there, "lu-THEE-ah") now.
I go by Lucy more often than not, though (and that's why I changed my name to Lucia in the first place). Lucia nn Lucy is fantastic, imo!
Gotta say, Paige does nothing for me as a middle name, but it's nice enough.
