[Facts] Re: meaning of name
Depends on where it's used, I think. Here in South Africa, moya is a normal dictionary word in the Zulu language, meaning either wind (the stuff that blows ..) or spirit (presumably because it leaves the body with the last breath). Also, in Christianity, the third person of the trinity. It sounds pretty, and fits in with our mostly European naming traditions (as CKE says), so it does get used as a given name - my husband actually wanted us to consider it when we were naming our kids.
We didn't, though, but that's another story!
