I have a problem with my grandfather. No one knows anything but there is a lot of hearsay. 1) probably J. Teofilo Frausto Martinez of Nadadores, Coahuila, born 06 Jan 1867. Siblings listed are: Ma. Brigida, Preciliana, J. Domingo, and Ma. Aurelia. However, I have been told he had a brother named Sebastian, and cousins: Ventura, Benito and Marcos. We believe Marcos lived near Kenedy, Texas. Is anyone related to any of the above. I was told Ventura changed his name to Sandoval and Marcos changed his name to Delgado. Sounds strange to me.
