Frances Culbertson-Irvin: Daughter of the Frontier

A roadside marker near Fort Benton commemorates Frances Culbertson-Irvin, who was born in eighteen fifty-nine and died in nineteen thirty-nine. She was the daughter of Alexander Culbertson, one of the most powerful fur traders on the northern Great Plains. Culbertson ran Fort Union for the American Fur Company through the eighteen forties and eighteen fifties, brokering relations between white traders and the Blackfoot, Assiniboine, and Crow nations.

Frances was born of his marriage to Natawista, a Blood Blackfoot woman who served as a crucial diplomatic bridge between her people and the company. Frances spent much of her life in Montana, witnessing the full arc of the frontier era, from the fur trade to statehood. Her memorial here, erected by her children, marks a family that stood at the crossroads of two worlds during one of the most consequential periods in the American West.
