Jph. Martin de Peña = Maria Rufina Ximenes

I am researching my maternal 5th Great Parents Joseph Martin de Peña and Maria Rufina Ximenes. They were married 08 Nov 1761 in Nuestra Senora de los Dolores, Teocaltiche, Jalisco, MX. I am seeking the names of their parents. (It appears that records for this time period have been omitted from the LDS digitized Mexico Records.)

Any assistance would be greatly appreciated.
