Genealogy Sources for Jerez, Zacatecas

I just got some valuable information that has allowed me to definitively connect a couple of my lineages to the Escobedo clan of Francisco Escobedo, founder of Monte Escobedo. This family married into nearly all of the prominent families in Jerez, Zacatecas so I have been persuing around the web and have come up on a couple of useful resources.

One is an online exposition of the genealogical research of someone whose roots are in Jerez... so there is tons of genealogical information on those old Jerez families: Carlos y Godoy, Llanos y Valdes, Escobedo, De Avila, De la Torre, etc.

The other is the history of the foundation of Jerez written by Leonardo de la Torre Berumen. I have posted this in the Books and Articles files section. It has the names of the first settlers in Jerez, which are many of the same names in the previously mentioned website.
