Brown (Byrd), Calvin
Calvin Brown is listed in the National Archives as Calvin Byrd*; he changed his name after the Civil War. An enslaved man, he ran away from his owner in Louisville, KY on August 14, 1864, then three days later enlisted in the 108th Infantry, Company A.
Brown fought in the Battle of Vicksburg in 1865; injured in that battle, he later became ill with an unrelated disease. In 1996, he and other African American Civil War soldiers were honored with the dedication of a national memorial site.
Calvin (Byrd) Brown was the great-grandfather of Mr. Shirley Foley, Jr.
