Nicolas Ximenes and Maria Gomes in Nochistlan/Mexticacan

I am researching my direct lineage thru Manuel de los Santos Ximenes, born around 1722 in Nochistlan/Mexticacan (not sure which for sure). His son, Miguel Antonio Ximenes, was born in Mexticacan, Jalisco, about 1758). If it helps, Miguel's wife was Margarita Clemencia Casillas y Franco de Paredes. They were married 27 May 1779 in Mexticacan.

Manuel's parents were Nicolas Ximenes and Maria Gomes. Manuel's wife was Angela Gertrudis Yniguez (b. ~1725). Manuel and Angela were married in Nochistlan on 24 Feb 1743. Angela's parents were Francisco Yniguez and Angela de Carabajal.

Part of the answer for me involves knowing more about the former Nochistlan. Was it only a town that corresponds to the present day town in Zacatecas, or was it something different in the past? I've not had much success tracking that down.

Thanks for any info!
