Church records of Cañadas de Obregon? Perez family?

Has anybody researched in or around Cañadas de Obregon? I'm looking for the church records for this town but they don't come out on familysearch. Were they ever filmed? And if not, are they located in another parish? I'm trying to find info on the Perez family (yes, those from the famous corrido), who may be related to my wife. I was able to find the civil registry of Cañadas, and the death certificates of Ysidro Perez, Mariano Perez, and Jesus Munoz Perez. However, I'm also interested in their church records since they may provide additional information about this family.

Any advice? I learned that the town was named Villa Obregon for several decades, but that name does not come out on familysearch either.
