In the late 19th century, Clay-Copton (who remarried after her first husband died) became an activist in the United Daughters of the Confederacy, a group established after the Civil War that was instrumental in shaping public discussions about the war and role of the South. She worked to raise funds for Confederate cemeteries and memorials. She also worked for women's suffrage. Clay-Copton was one of a number of Southern women to publish her memoir at the turn of the 20th century; these women's accounts became part of the public discourse about the war. The United Daughters of the Confederacy specifically recommended her book as one of three for serious discussion by the membership. Such works helped shape memories of the antebellum years and the Lost Cause.
