I know that my grandfather, Carlos Saenz, said that his father Gregorio Saenz was from Chihuahua Mexico. Gregorio Saenz married Emetaria Nunoz. They had Marian, Felisa (Jennie), Carlos, and Dioncia (Aunt Dee). There were also a few babies that didn't make it.
After Emeteria died, Gregorio moved to Texas and remarried. I remember going to visit him and meeting my Grandpa's half brother. So I know that there are more siblings.
If you need more info, let me know.
I hope this helps.
