I am searching for my paternal grandfather's lineage. His name was Pedro Salcido born around 1910-1911 in Tubac, Az. He married Trinidad Marcolfa Kaphan, also from Tubac. They had 3 children, Pedro, (my father born May 15, 1938), Olga and Jose Salcido. My grandfather died around 1964-65 in Tucson, Az. Any leads would be greatly appreciated!
