Here I go with an reply to myself.
I recently found the parental names of licenciado Jesús Acuña (Jr.) (my maternal great grandfather). He was the son of Jesús Acuña (Sr.) and Mariana
Narro both of Saltillo. I have not found their birth or marriage death records yet although I do know that Jesús Acuña (Sr.) was still alive in 1918 when accompanied my great grandfather to
Austin,
Texas having fled there after an assasination attempt was made on Jesús (Jr.)
I also found the name of my great grandfather's wife - Enriqueta
Rodriguez Morales, born on 16 September, 1890 in Saltillo. I also found the names of their nine children:
Bernardo, Enrique, Roberto, Jesús(b.abt.1913), Servando(b. abt.1914), Ana Maria (b. 1916),
Guillermo(b. 1918),
Raymundo(b.1921) and Gertrudis (b.1928). It should also be noted that this said Enriqueta was not my great grandmother. He had only one daughter - my grandmother Carmen - from his laison with my great grandmother Margarita
Ramirez.
