Introduction, Montalvo Cabral Research

Hello everyone, my name is Adrian and I've been a part of this group for over a month now, but just recently had part of my family tree uploaded so I would like to introduce myself to everyone.

The line I am reseraching here is that of my maternal grandfather, with the surname of Montalvo. Aside from the fact that this name is not common, it seems that upon doing a search of the forums for a mention of that name, only a few posts were found and those were of names mixed into the resources of other's.
Well, a history of my family, my great grandfather was Clemente Montalvo, he was from Villanueva, Zacatecas. Although originally I believed he was one of 5 children, I have found the baptism documents of 5 other siblings. His parents were Isabel Montalvo and Maria Huerta. That is where the geneological information on that side of my family ends. I have never been able to find any records of Isabel Montalvo, and the same with Maria Huerta, which as one would imagine is a fairly common name. I have been told one way or another she is related to Victoriano Huerta but I have yet to find her name on that family tree. As for Isabel, I am not sure if he is even from Zacatecas, as the story is told to me by my family is that he was a participant at the Battle of Puebla in 1862 and the subsequent siege the following year. Looking at the list of Mexican regiments which participated at the battle, most came from central Mexico. He could have been in the regular army, but for that information I still need where he was from.

As for the other half of my grandfather's family, thanks to a distant relative I have more information. Clemente Montalvo married Patricia Cabral sometime in the first decade of the 20th century. The Cabral's were from Jerez, Zacatecas. However, her mother was a Rojas and they were from Tepetongo.
Here is a link to the Cabral-Rojas family tree. It goes back about 3 generations started from my great-grandparents. http://www.nuestrosranchos.com/es/node/18460

Perhaps I might find a distant relative or two here. Thanks.
