According to Shirley Dinwiddie Scott of Florance, Montana John used the nick
name "Mack". He died when he was about 21 from a 'risen' in his ear. His
daughter Quaid was born in 1892.
Quaid was born around her fathers death. Her name is found in a letter written
by Shirley Dinwiddie Scott of Florence, Montana. I'm not sure of her sources.
