Very Old Antique Hand Carved Mary Holding Baby Jesus Signed "Villa Luis"

I've had this carving about maybe 25 years,signed "Villa Luis" no date.I got this out of an old storage auction.I had a friend who looked at it once and told me I need to get it appraised.Well she passed and I had no one to help.Now I'm trying to find out some kind of information.My friend when she was living told me to don't sell it if possible cheap.So any idea

 

Are you sure that's wood and not cast? I ask because the grain goes a different direction on the back then it does on the front. Not that old, 1970s perhaps. "Villa Luis" doesn't make much sense although Villa is a surname and Luis a first. But reversed not a common usage in Spanish-speaking countries.

Yes 100% wood.
