Esparza Family from Noria de los Angeles and El Hacienda Corro

I am interested to know if anyone is familiar with the terrain of Zacatecas and the ranchos nearby. Mariano Esparza was from an area called Corro in Zacatecas. I am having difficulty finding Corro on the map of Zacatecas. If anyone has any information or any family line that trace to the Corro area or Noria de los angeles please write back.
