Hi, John. I too am currently working on the Balderrama family tree. My great grandfather was Jose Balderrama from Chihuahua, Chih. I understand he came from a large family, but I have yet to locate his birth certificate or siblings. He married my great grandmother Ramona Gutierrez in the early 1800's. I have a cousin in Chihuahua City who is currently working on tracing the family as well. Let me know if these names sound familiar. I have a lot more information to share if they do?
