Felipa Ramona Guadalaxara and Jose Montano Bernal from Aguascalientes

Greetings everyone: I am a new member of this group. My mother’s family is from Aguascalientes. I am trying to identify the parents of my fifth great-grandparents: Felipa Ramona Guadalaxara and Jose Montano Bernal from Aguascalientes. Felipa was likely born around 1760. I cannot find the couple’s marriage record. Their first child was Maria Regina Bernal, b. 1775. It looks like they lived at the Rancho of San Antonio de Buena Vista after Felipa married Jose Montano as their second child (Jose Ignes Guadalupe Montano Bernal b. 1778) was baptized there, and they were still residing there when Ma. Regina married in 1775. Any information or leads on finding their parents would be much appreciated.
