I too am researching my Hernandez side of my family. So far I found that my Grandfather Arturo Hernandez was baptised in Jalpa, Zacatecas. His fathers names is Ildefonso. But as far as that I have nothing else. So I am always doing research. I use LDS site alot and have ordered films to do more research. So I typed in a few names you had listed and came across this information. Just in case you haven't.
