The elders sent Black Shawl to heal Crazy Horse after his altercation with No Water. She was known at the time as having skill in treating bullet wounds.
Black Shawl was presented to Crazy Horse as a potential bride when she was twenty-four, which was considered late for a betrothal. Crazy Horse was twenty-eight when marriage was discussed between the two families.
She had a daughter in 1871, named They Are Afraid of Her. They Are Afraid of Her died at age three, likely of cholera. Black Shawl also suffered the same disease, and was treated by Dr. Valentine McGillycuddy.
Crazy Horse's relationship with Black Shawl lasted longer than the other two romantic relationships that he had in his life. They were known to be "sociable in the tipi", indicating a contented home life, and she supported his life as a warrior.
Black Shawl outlived Crazy Horse. She died in 1927 during the influenza outbreaks of the 1920s.
