Margaret Irvin Sullivant Carrington was married to Col. Henry B. Carrington, commander of Fort Phil Kearny in present-day northeastern Wyoming. She wrote Absaraka, Home of the Crows, first published in 1868, based on her journal about life on the Great Plains of the Western frontier. She was present at the fort when the infamous Fetterman Massacre occurred on December 21, 1866.
It was considered the worst military disaster of the Indian Wars before the Battle of the Little Big Horn 10 years later. After Margaret’s death in 1870, Carrington brought out new editions of the book with expanded details of his own experiences.
