quadroon a person of mixed race whose ancestry includes one grandparent of African descent and three of European. (Quadroon, octoroon, and similar terms were used to make distinctions in a complex system of social and legal status developed in some Caribbean societies. In the United States, they were apparently used less exactly; Stowe uses mulatto throughout the novel to refer to people of mixed race, and quadroon to refer to African-American people very light in complexion, even when the person's exact ancestry is not known.)
Jim Crow a generic name formerly used by Southern whites for African and African-American people, especially boys or young men; used slightingly.
Wilberforce William Wilberforce (1759–1833), English statesman and vigorous opponent of slavery.
