Need help finding Pedro Jose Thorres married to Maria Manuel Ortiz

I truly need help find my 8th generation grandparents Juan Antonio Thorres de Escobar married to Getrudis Codero. They were from San Juan Bautista, Sombrerete, Zacatecas Mexico.

I also need to find Ysidro Placencia married to Gertrudis Rodriguez around 1712.

Mil gracias
