Monica, I am the daughter of Daniel Ruiz of San Diego formerly of Dixon, CA. He is the son of Petra Rubalcava and Tereso Ruiz, my dad says they moved to Los Angeles from Juchipila to get away from the Mexican Civil War. Later settled in Ensenada Mexico. Petra and Tereso had Conrad, Daniel, Francisco/Pancho, Jessie, Gloria and Moises. Which one of them is your grandparent? I know we are related. I may have found Petra Rubalcava and Tereso Ruiz marriage license at Ventura County Records I am going to order to and hope their parents are listed.
