My grandfather is Leonides Venzor Aguirre of Chihuahua. He was born in 1886, where exactly I don't know. As far as I know he was only married once to Isaura Duran of Ysleta, El Paso. He died when he was about 37 in a car accident. I have more information on him and pictures.
Are you sure you have the correct spelling of his name? Are you sure your family was from Spain? Back in those days people would often times said they were Spanish because it was better than being Mexican.
