I am a grandson of Mateo Guerra. He was born 2/14/1903 as a young man he drove a wrecking tow truck and became a plumber. My grandfather was from The Cirlce area in San Antonio on Zazamora. I believe he had 3 brothers, Tomas and one they called Buffalo, I don't know all their names. Please contact me if you have any family information. I still have famiy in the area and visit 2-3 times a year.
