She was the daughter of Nathan Fiske, a professor at Amherst (Mass.) College. She lived the life of a young army wife, traveling from post to post, and after the deaths of her first husband, Captain Edward Hunt, and her two sons, in 1863 she turned to writing. She married William Jackson in 1875 and moved to Colorado. A prolific writer, she is remembered primarily for her efforts on behalf of the American Indians. A Century of Dishonor (1881) arraigned government Indian policy; her subsequent appointment to a federal commission investigating the plight of Indians on missions provided material for Ramona (1884), which aroused public sentiment but has been admired chiefly for its romantic picture of old California.
