My grandfather lived in Presidio for a few years,back in the early 1900's. He was born in Delicias, Mexico and came to the US around 1890, to work in the Shafter siver mines. Jesus Telles Mendosa and Patricia Valdez Mendosa (my grandmother), finally settled in Candelaria, Tx. I also had an uncle (Manuel Telles Mendosa, married to Cleofas Lujan), who lived in Presidio for many years. I think he also came from the Delicias and Cuchillo area.
