My Great Grandfather Gabino David Martinez was born in Candela, Coahuila according to family tradition. His parents Francisco and Josefa died when he was still a adolescent and left him and his brother, whose name was lost. When his brother was drafted in the the Army during the revolution Gabino left to Texas. We have no information on the family other than this story. If any of this rings a bell to anyone out there. Drop me a line.
