García Family, Teocaltiche, JAL

I was hoping that someone within this community may have some more information on this family pre-1850s.

From my own family (and confirmed through Ancestry.com), I knew about Pedro García and his wife Maria Refugio Aguilera (1816-1901), both from Teocaltiche, Jalisco. Through one of their children's marriage certificates, I found their parents from both sides: Lorenzo García and Agapita de la Paz, and Juan Nepomuceno Aguilera (b.1775) and Maria Rosa Aguilera (b.1790).

I'm not sure if Ancestry.com is lacking in Mexican historical records, or if this time period just gets tricky to find information for. But I have not been able to find anything for Lorenzo García and Agapita de la Paz, except for their grandchild's marriage certificate they are mentioned in. Not a single record...

Any help would be greatly appreciated.
