Ocegueras in Tamazula

It makes me sad that a lot of my ancestors from Tamazula came from Cotija and I can't find anymore information.

In this case my ancestor was from Sahuayo according to his marriage record, it also mentions that they received a dispensation from the Bishop.... it must have been from Guadalajara, but I can't find anything on that year on the dispensations page nor their IM (Informacion Matrimonial) which would probably have the information on the relatives.

Any information you guys may know or have is appreciated

The persons in question are:

José María Oceguera 963L-Z3J​​
Marriage: 07 MAY 1849
San Francisco,Tamazula De Gordiano
Maria Lorenza Alvarez (o Arreguin) Contreras K26Y-287
