Villanueva, Zacatecas records

Hello all, I was wondering if any member here has gone through the Bautismo 1796-1851 or the Matrimonios 1806-1871 records for Villanueva. As both records are mixed with other's, and also include the towns and ranches around Villanueva, it has been hard for me to find the exact records for the town of Villanueva itself. In fact, I haven't found many records that say the town of Villanueva, but instead with the names of surrounding ranches instead.

Have I missed the pages where the Villanueva records are located, or is it that those books did not contain records for the town of Villanueva? Any help would be appreciated.
