Daddy says the Prewitts were a pretty mean lot. Grandpa had one brother named John. Dad says he had a pretty bad temper. The story goes that Grandpa and Uncle John were working in an oat field. They had their horses tethered some ways away. Some man (Daddy doesn't remember his name) who had had a run in with John turned Grandpa's horse loose - thinking it was John's. They happened to see him so Uncle John got on his horse and caught up with the man and told him "If I find Jim's horse, OK. But if I don't I'll kill you, you S.O.B."
That same evening, John was shot in an ambush - but not before he saw his assailant. He lived long enough to extract a promise from Grandpa to avenge his death. For two years after that Grandpa and this man waylaid each other, never taking more than potshots. The man was a horse trader and sneaked into town occasionally to do some horse dealing. Grandpa had a "lady friend" who informed him of the movements of this man. Once when he came into town Grandpa followed him out and waited until he made camp for the night, then called him out and killed him. Grandpa rode his horse to death getting back to town. Before he was missed a friend brought him a fresh horse before he got into town and they rode in together cool as could be. Most people suspected who had done the killing but it never came to trial and most people believed it was just reward.
