There is no film available from LDS vefore the one with marriage and baptisms for this family.Kind of run out of resources to check.
If your spanish is good you might try contacting the local cronista for the town. I have found list of cronistas by web surfing but I usually don't see phone or email addresses. Plus my spanish is not fluent.
A visit to the town and checking protocolos might be helpful.I can not travel because of my health.
