Need help with Zacatecas

Perhaps someone can guide me in the right direction......my brick wall is
"Zacatecas, Zac." where my ancestor, Juan Antonio Liendo and his wife
Catalina de la Rosa gave birth to their son also named Juan Antonio Liendo.
In the will of Juan Antonio Liendo (the son) he states (in 1771) that he was
"originario de Zacatecas, Zac" but he does not give the name of a Rancho or
any other town. I am assuming he (the son) was born around 1700. My focus
on the SLC trip is to find records on the son and on his parents as well.

Can anyone tell me what towns or ranchos may have existed in or around the
city of Zacatecas in the late 1600s or very early 1700s?

Thanks!
