Looking for relatives of Tomisita, Roque, Raymond, and Petra Barrera, siblings from Ceralvo, NL. Tomisita and Roque went to Colorado sometime around 1905, following the death of their father, who had a ranch outside of Ceralvo. Supposedly hung by men supporting Caranza, when he refused to provide guns and horses. Raymond went to LA where he was a chef and Petra lived in Ceralvo and Brownsville TX. Her son, Chevo, lived in Chicago. Any assistance appreciated to help me find information on her parents, grandparents, etc.
