Searching for Gonzalez Loza Family Information (Canadas de Obregon)

Hello,
I am looking for information on my Gonzalez/Loza family from Canadas de Obregon. My great grandparents are Francisco "Pancho Bigotes" Gonzalez Gama and Juana Loza Aguayo. They had 5 children together; Eduviges, Manuel, twins Agapito & Guadalupe, and Santos Gonzalez. They lived in Rancho El Cerro Viejo in 1930 and might have lived in Rancho El Pandito. I am also wondering if anyone knows how to research criminal records or newspaper records (if any at that time) from that area.

I have not been able to find any close related relatives that might still be in that area nor have I been able to find any traces or documents for some relatives after the 1940's. I would really appreciate any help! Thank you.
