Estancia de San Nicolas en Jerez o Tepetongo

I have been researching my ancestors and I found Teodoro Valdes born in "Estancia de San Nicolas". Does anyone know if this is the same place as the "Estancia de Los Berumen"? The Baptismal Certificate is from 1787 in Tepetongo Zacatecas. I researched on the internet and I seem to find an Estancia de San Nicolas in the Municipio de Valparaiso Zacatecas. On the Jerez Facebook page they have a history of the town and Mention an Estancia de San Nicolas but they don't specify the location or any other details.

Any information anyone may have would be helpful.

Thanks
