For those of you doing research into the Mendoza Surname this is the information that I have come across in my research:

Salvador Mendoza - Bruna Gomez (GGGGrandfather Salvador born 1820's?)
Encarnacion Mendoza - Romana Cedillo (GGGrandfather Encarnacion born 1840's?)
Zenon Cedillo Mendoza - Rosa Ramirez (GGrandfather Zenon born 1860's?)
Ruperto Mendoza - Tomasa Hernandez (Grandfather Ruperto born 1890's)

I do not know where Salvador Mendoza was born but do know that the rest of my grandfathers were born in the Jalisco area. Hope this information might help someone doing research. I also have images of the names as they are related should you need them. Thanks
