Hi Victor,
I think that I have found the information that you might be looking for. I have been doing genealogy for over 15 years because I wanted to know more about my family and had luck with my grandfather's mother's side but none with my grandfather's father's side. So, I have found people search databases to be useful in my search. At one time, I used to be able to type my grandfather's name which is Leon Aguirre short for Leonardo Rodriguez Aguirre and your sister's name Lucilla/Lucila Aguirre Araiza appeared in the databases but now it doesn't show. I just used her name again and my grandfather's name shows. I can make a connection with your family because you and your sister are apart of my grandfather's family. You see my great grandfather Leonardo Rodriguez Aguirre Sr. came over from New Mexico to Coleman, Texas for the Army National Guard back somewhere around 1940's (found this on Ancestry's World War II file). He also had a grocery store that he opened from what I heard. His brother Benjamin Rodriguez Aguirre also came to Texas as well. Their mother's name is Cecilia Rodriguez or Cecilia Aguirre. I believe these are the other 2 brothers that go on the list of your grandfather Victoriano. As you may know now, our families tend to use the same names of past family members that they resemble. I think that is why your name is similar to your grandfather's name because you have some sort of resemblance.

UPDATE: My great grandfather's name is actually Leonardo Galindo Aguirre and my grandfather is Leonardo Rodriguez Aguirre making him not a senior. I recently found out my great great grandmother's name is Cecilia Galindo Aguirre instead of Cecilia Rodriguez. She was born in Galeana, Nuevo Leon, Mexico.
