Answer:
Narcissa Whitman.
Explanation:
Narcissa Prentiss Whitman was the first woman missionary to go to Oregon Country from New York. She crossed the Rocky Mountains and along with her husband Marcus Whitman, founded the Whitman Mission.
The couple went to the Oregon Country to try to civilize and Christianize the Cayuse Indians. Her aim was to try to help bring as many natives as she can to Christianity. Their efforts then turn to paving a way for the whites to gain access to the Oregon trial. But the plan did not work and the Cayuse natives murdered her and her family in Walla Walla in 1847.
