Rancho de Encinillas - Tlaltenango de Sanchez Roman, Zacatecas

My great grandfather, Antonio Valenzuela, was born in Rancho de Encinillas of Tlaltenango de Sanchez Roman, Zacatecas, on June 13, 1901, according to his birth certificate, to Jose Gregorio Valenzuela (between 70 and 80 years old at the time) and Juana Velasquez (around 20 years old at the time). I have a few questions I haven't been able to answer yet. I will post them below in case any names of places / people ring a bell:

1) Does anyone know if Rancho de Encinillas in Tlaltenango de Sanchez Roman was a kind of peon's hacienda? I am looking for any information possible about this ranch, as there seems to exist almost none online.

2) Is anyone familiar with the role of Tlaltenango de Sanchez Roman during the Mexican revolution? According to oral histories in my family, the abovementioned Juana Velasquez, who was the daughter of Severo Velasquez and Felipe Minjares, abandoned her children to fight in the revolution in the early 1900s. She was also a curandera-medium. I am trying to find other instances of young women from Tlaltenango de Sanchez Roman who might have had involvement in the revolution. Does anyone have such instances in their family histories?

3) The abovementioned Gregorio Valenzuela was near the end of his life when he met Juana Velasquez and had three children with her, including the abovementioned Antonio Valenzuela. According to oral histories in my family, Gregorio had a wife and several daughters with another woman prior to meeting Juana Velasquez. Gregorio is the descendant of Jose Valenzuela (born about 1802 in Tepechitlán, Zacatecas) and Rita Bañuelos (birth unknown), who were married in 1822 in Tepechitlán Zacatecas and had the following children: Florentina Valenzuela Bañuelos, Maria Ramona Timotea Valenzuela Banuelos, and Jose Gregorio Valenzuela Banuelos (born about 1828). Is anyone on here related to Gregorio Valenzuela, perhaps from his first marriage?
