I just got that book the other day. Haven't started reading it yet.
After two years of searching i was finally able to find my grandfathers family. They came from Mexquitic de carmona.
They are Ortiz and Hernandez. My great grandfather Cenovio Ortiz left Mexquitic and never went back or even mentioned this place to his children. His Brother Damaso Ortiz and Mother Hermengilda Hernandez show up in the 1930 mexico Census so it appears he came to the U.S. alone.
Cenovio Lived in Gonzalez Texas for most of his Childrens births, and later retired to Rio Bravo, Mexico.
Are there any other Ortiz or Hernandez family out there?
