Who was Rebecca Felton? The first woman to serve in the US Senate. Also "a prominent society woman; an advocate of prison reform, women's suffrage and educational modernization; and one of the few prominent women who spoke in favor of lynching." She was from Georgia.
Mentioned in "American Tapestry, The Story of the Black, White, and Multiracial Ancestors of Michelle Obama" by Rachel Swarns, which I'm finding interesting.
