I know very little about my great-grandfather, Manuel Olivas Sr. He was born maybe around 1865-73. He was married to Balbaneda Almanza in about 1880, they had 11 children of which 6 survived. He abandoned the family in 1911 in order to follow Pancho Villa during the mexican revolution. It was know that after the revolution he lived with a woman and had other children. He died in Aug. or Sept. 1937 in Chihuahua. I think the family was from Sta. Rosalia or Chihuahua, Chihuahua. Any information would be greatly appreciated.
