Well, I was born and live in Dallas TX. My mom is from Sabinas Coahuila. Her name was Elda Esmeralda Castillo Farias. Her parents were Jose Guadalupe Castillo and Socorro Farias. I don't any names further down from there but I do recall my mom mentioning the name Saucedo when she explained a little about the names. I do not know how much that would be. I am trying to find some ancestors as well. Mainly a half brother my mother told me about that is from my father's side but I have had no luck finding. My birth father's name was Eduardo Hernandez. That is all I know.
