Hi, I am fairly new to this forum so please excuse me if I do something wrong. 

I have several ancestors from the Celaya area, and I am wondering if anyone has information about the parents of Pedro Buitrón Mujica AKA Pedro Vallejo born c.1700 in Celaya and married to Catarina Tena Padilla in 01/FEB/1736 in Celaya. 
I am aware he is a “clandestine” son of Francisco Buitrón Mujica, and from the glances I was able to find as previews from “Los Tena de Celaya” by Rafael Nieto y Cortadellas, it looks like his mother might be Manuela Vallejo García (Daugther of Diego Vallejo Torres and Juana García Diosdado), but I haven’t been able to find documentation to confirm this, so any help will be greatly appreciated.

I have read in “Retoños de España…” and in this forum that Mr. hfaizcorbe, you are and expert in the region so I would love to know if you have any information regarding this family. 

Thank you in advance,

Salvador Rivas
