Hello Francesco Elia,
I would be very interested in learning about your family in Castelveltrano, Sicily. The Elia's I am looking for are from Cosenza, Italy but that isn't so very far away. I don't know how to email you personally, so I am posting this to the Elia family message board in case you see it. If you want to reply, my email address is jbannerman@home.com
I am not an Elia myself, but my partner's mother is an Elia - so what I know, I have learned from her. Talk to you soon maybe.
