Gutierre de Aguila

I have run into a few ancestors who moved to the Totatiche area from Gutierre de Aguila in the early 1700s. I remember discussing with someone that the name of this town had changed to Villanueva (Zacatecas). I was looking through the films for Villanueva and it seems that the early years of that parrish are missing... the only films available appear to be informaciones matrimoniales.

Has anyone looked at Villanueva films? Am I correct that is the modern name of Gutierre de Aguila? What other jurisdiccions might people have been baptized in if they were born on an Hacienda in the region of Gutierre de Aguila?
