Thirtieth Convention of the Kentucky Equal Rights Association
Laura Clay (February 9, 1849 — June 29, 1941) grew up in a large family of activists at a farm in Madison County. Her father, Cassius Clay, was a friend of Abraham Lincoln and ambassador to Russia. Her mother, Mary Jane Warfield Clay, and her sisters all supported the woman suffrage movement, and farming kept them economically independent as they went on in life, whether divorced or married.
