Hi! My mother Emilia Galvan Lozano had a cousin Gilberto Lozano who moved to California around the 1950's maybe. They are from the Coahuila / Texas border. Her father's name was Hilario Galvan and her mother Gregoria Lozano. My Grandmother "Goyita" had lived in San Pedro de las Colonias, Coah. Does this make any connections to your family tree?
