El Salitrillo, Zacatecas

I have recently discovered more generations on my father's side. They include the surnames Tinajero, Olague, Valdez, Feliz, Flores, Suriano, Salasar, Munos, Lucio, Vasquez, Garcia, Quijas, Banegas, Escobedo and possibly Mata. Most of these were baptized or married in Tepetongo, Zacatecas, but they lived in a community called El Salitrillo in the early 1700's to the late 1800's. Does anyone else have any connection to these families from this location? Both the men and the women used various surnames, but my research has proved that they are one and the same. For example, my great-grandmother Rafaela used the surnames Tinajero, Flores, Felix, or Suriano. Her father Hilario (Ylario) used the surnames Tinajero or Felix. Her mother Teodocia Flores also would sometimes use the surnames Felix or Suriano. This made finding their children a challenge, to put it mildly. I finally found my grandfather as Francisco Olague Felix, when I expected to find him as Francisco Olague Tinajero. Many of the other branches did the same thing, and the same surnames run in my father's paternal and maternal sides. It seems no one ever moved and everyone would marry into the same clans over and over again. Kind of reminds me of the stories you hear of clans in the Appalachians.

I have not been able to find El Salitrillo on any map, but I did find a list of several places with the same name in the states of Aguascalientes, Zacatecas, Nuevo Leon, and Tamaulipas. The list gives the Latitude and Longitude for each. The El Salitrillo in Zacatecas is at Latitude 24.5333333 and Longitude -101.1166667. Does anyone know of a map showing this El Salitrillo?
