Parents of Jose Joaquin de Leon

I have been trying for months and searching for my GGGrandfather, Jose Joaquin de Leon
born San Francisco del Rincon, Gto? around 1700? He was married to Sixta Hernandez.
I have found the children, but not successful in finding the birth date, place and marriage of Jose Joaquin de Leon.

Can anyone please help me find more info...I certainly would appreciate it.

Thank you,

Ann Marie Gutierrez
