Looking for Sanchez

Hi everyone,

I’m looking for records on Doroteo Sanchez and Micaela Morillo parents of Gregorio Sanchez born on the 8th of May 1814 in la Raíces, Arandas, Jalisco Mexico. I found the baptism record but can’t find anything more going back. Hoping someone has them on their family tree. I have attached the baptism record attached.
