Family Santoyo-Diaz (de Leon?) Ojuelos-Cienega de Mata

My great-grandfather's grandfather Jose Lorenso Santoyo (born abt. 1775) was son of Joseph (Manuel?) Santoyo and Maria Josefa Diaz (de Leon?). I have not been able to find Jose Lorenso's birth certificate, but in his marriage (11 may 1808, San Jose de Ojuelos, Jal) to Maria Josefa Masias the parents of both are listed. In a search of Jose Lorenso's siblings I found the following individuals whom I believe, by the names of the parents, the timeline (1770-1802) and the places (all localities linked to Cienega de Mata & Ojuelos), to be siblings.

I would expect that the records 1&2 (christening) would be the most useful. Hopefully the names of the grandparents are listed helping confirm all these individuals as the same family. The name Jose (Joseph or Josse) Manuel in combination with Santoyo (Santollo) with Maria Josefa Dias (or Diaz) or Dias de Leon, indicates that there is a good chance that is the case. Does anyone has any of these films on loan, particularly the christenings to solve this question? It would be a great help.
Thanks, Jaime
