Sarah Moore Grimké (1792–1873) and Angelina Emily Grimké (1805–1879), known as the Grimké sisters, were the first American female advocates of abolition and women's rights. They were writers, orators, and educators. Learning that their late brother had had three mixed-race sons, they helped the boys get educations in the North. Archibald and Francis J. Grimké stayed in the North, Francis becoming a Presbyterian preacher, but their younger brother John returned to the South.
