Valdivia Family

I am trying to find information on my husband's maternal grandfather, Emilio Valdivia. His father was Tomas Valdivia, and his mother was Secundina Ramos. Does anyone have these names in their family tree?

Emilio Valdivia was in the seminary in Totatiche at the time of the Cristero War, and had to leave to avoid being killed. He immigrated to Southern California.

We cannot locate any information regarding Emilio's family. I don't know if he was from the area around Totatiche or somewhere else. We have heard that he might have been from an area in Zacatecas that wasn't too far from Totatiche. Knowing nothing of the area, I have no idea where that might be.

Does anyone know anything about any Valdivia families around Totatiche, or are there any Valdivia's in Southern Zacatecas? Can anyone give me any ideas of how to research the family of Emilio Valdivia?

Thanks for any help you can offer.
