From my grandfather's side, I had found the following:
Grandfather Pascual De La Torre. Son of Preciliano De La Torre and Apolonia De La Torre. Preciliano is the son of Ramon De La Torre and Cesarea Nava. Apolonia De La Torre is daughter of Jose De La Torre and Maria Dolores "Lolita" Villareal. Jose De La Torre is the son of Pedro De La Torre who is son of Preciliano De La Torre and Bernarda Carbral.
I verified with my grandfather the authenticity of his ancestors. So far, he has been able to confirm that Ramon De La Torre and Cesarea Nava and Maria Dolores Villarreal and Jose De La Torre are his grandparents.
He stated that Ramon was shot to death during the Mexican Revolution by a Soldier who was on top of the Church's bell towers. He also said his other grandfather Jose De La Torre was also killed. Both mothers died from natural causes.
Any information linked to my research would be helpful.
