The Federal government first Grant all American women the right to vote on 1920.
George Washington Bush and another family, the Simmons, moved west on the Oregon Trail, but by the time they got there, a law was past that African Americans could not settle in the Oregon Territory, so instead they moved cross the Columbia River into land owned by both Great Britain and the United states, and the Bush's and five other families created a settlement there called "Bush Prairie."
Bush's experience as a multi-racial (Irish and African) person show the interdependence of people of different races on the western frontier, as well as the difficulties regarding racial prejudice.
Hope this helps.
