Perez(s) and Hernandez of San Matias, Pinos, Zacatecas

Hi! I am a new member and I am researching my husband's family tree. Here is my link to what I have uploaded so far.

I am currently working on Francisco Perez(s) and Petra (Petronila) Hernandez (born about 1800). Francisco was born about 1795 and married Petra about 1820. Their first son, Clemente, was born in 1821. Followed by Ysidro, Maria Gregoria, Pedro, Jose Marcelino, Antonio, Sabino, Dario, Epigmenio, and Vicente Nepomeceno. The children were baptized in San Matias, Pinos, Zacatecas. Some of them ended up in Teocaltiche, Jalisco and others went to Santa Rita, Zacatecas.

I am needing help on tracking down more information on Francisco Perez's parents, who are Diego Peres and Maria. I am also stopped at Petra's parents, Francisco Hernandez and Juana. Has anyone came across these names before?

My husband is from Dario Perez's line. Dario married Maria Teodosia (Teodoria) Castaneda. Delgado and Lopez are the family names that the other siblings married into. I have more information on them if needed.

Here is a link to what I have submitted so far. There isn't any information on the Perez line other than the great parent listed as I am still working on this line. I will upload this line once it is more put together. I have other lines that I will upload to my link as soon as I do more work on them as well.
