Scribes for Zacatecas Civil Records in San Pedro Ocampo

I'm hoping to find information on a Adolfo Martinez B. who was (a judge?) in charge of documenting entries for civil records during 1916 records I found. He was probably the scribe for many years, however, I have not researched how many years he was there. He is father to a Martinez line on my family tree. The Martinez families were merchants and probably well known community Dons.

In some entries there is mention of Hacienda El Carro where the Martinez family lived, not sure what years these were. I looked for information on this Hacienda but did not find specific history of the people living there. I'm looking for information about the people who worked there such as the ranch foremen, servants and so on. Some Martinez folks are identified as mixed.
