Based on the life of Marie Dorion, the first mother to cross the Rocky Mountains and remain in the Northwest, A Name of Her Own is the fictionalized adventure account of a real womans fight to settle in a new landscape, survive in a nation at war, protect her sons and raise them well and, despite an abusive, alcoholic husband, keep her marriage together. With two rambunctious young sons to raise, Marie Dorion refuses to be left behind in St. Louis when her husband heads West with the Wilson Hunt Astoria expedition of 1811. Faced with hostile landscapes, an untried expedition leader, and her volatile husband, Marie finds that the daring act she hoped would bind her family together may in the end tear them apart. On the journey, Marie meets up with the famous Lewis and Clark interpreter, Sacagawea.
