Hi Martie: The surnames look very promising, but the dates do not. My grandmother Cresencia must have been born in the late 1800's. She died in Laredo MX in 1958. Also the farthest name in the tree that I know is thet of my gramps: Agustin Ovalle and granny Cresencia Rivera. I do not know their second surnames (Apellido materno). I still sincerelly appreciate your e-mail and ask you to keep posting whatever information you have on our unusual and mysterious last name as it appears to be..
