All I know about this great grand father, is that he died when he went hunting with a group of his workers. They ate fish and a fishbone got stuck in his throught. He died of that.
I think his name is supposed to be Cornelis, not Cornelus. My father is named Cornelis Johannes. Maybe after him. Then he might be the other brother, and not this brother, Cornelus August Eduard? I would so appreciate if someone can help. He was deffinetly maried to Catharina Maria (de la Rey). My aunt is named after her. She was the youngest of the 10 De la Rey children. (Father Genl Koos de la Rey).
Cornelis August Eduard (i) was born in 1858 in Rustenburg and died in 1932 at Thabazimbi. He married Catherina Maria de la Rey in 1881. He had 13 children, however, I do not have a Cornelis Johannes listed as a son on the death notice. Perhaps you could help a little with the dates and places of birth of your parents. Or you could go to myheritage.com and look for the Pistorius RSA Five Brothers tree and see what you can find.
