I have looked at some of the records that support your family tree, and I find they lived on different ranchos in the Nochistlán vicinity at different times: Monte de Duranes, Noche Buena, Tlachicila, Santa Ysabel, Salitre, and possibly others. From the birth, baptism, and marriage records it is not possible to tell if they owned these places. Also, I have not seen anyone addressed as Don or Doña, which could be indicative of some stature in their communities.
The ranchos all typically have names. I have not seen a “Rancho de Olmos,” but that by itself has no significance, as the ranchos had a variety of interesting names, and using family names seems to be less common.
You may want to consider joining the Nuestros Ranchos internet genealogy group. They focus on the Los Altos region of Mexico, which is Jalisco, Zacatecas, and Aguascalientes. To join you would need to provide an example of your research, but membership is free.
