My great-grandmother was named Adela Legarreta (Mama Lala) and her maiden name was Leyva. Her parent's names were Manuel Leyva and Felipa Leyva. Adela was married to Joaquin Legarreta and one of their many children was my grandmother, Clotilde Villalobos. Adela died at the approximate age of 96 in about 1958 and is buried in Fort Hancock, Texas. I have been told that Adela had a sister named Tia Tina who was married to a man named Jose Urquide. One of my aunts told me that she remembered that the family came from a ranch near Camargo, Chihuahua, Mexico--Santa Rosalia, I believe. Is this any help?
