My name is Jason Cervantes and I am also researching the area around Santiago Papasquiaro, Some of my Nevarez relatives are mentioned in your message. Juan Jose Nevarez m. Guadalupe Corral, and Jose Nicolas Nevarez m. Mathilde Luiza Corral. Juan Jose is the son of Jose Nicolas and Mathilde Luiza. I would like to share some info if possible about some of the other surnames that I am researching. My direct line is that of the Carrete and Sanchez families. Let me know if this would be something that you may be interested in.
