I can't believe I found this post. It's very old so I'm not even sure you are still checking, but if you are, I'm 100 % positive I know your family. My grandfather was Jeronimo Villalpando Rios. He was from Tepa and had a brother named Miguel. I have an uncle named Porfirio and I've also heard the other names you've mentioned. If you receive this message please reply. I'm sure my mom would love to know more about my grandfather's family.
