Otelia Butler Mahone (August 1, 1835 February 11, 1911) from Smithfield, Virginia was a nurse during the American Civil War and the wife of Confederate Major General William Mahone, who was a civil engineer, teacher, railroad builder, and Senator in the United States Congress. Popularly known in Virginia as the "Hero of the Battle of the Crater" during and after the Civil War, her small-of-stature husband was nicknamed "Little Billy." An illustrious "character" in her own right, strong-willed Otelia Butler Mahone became almost as well-known as her famous husband. She is credited by local legend with the naming of the towns of Windsor, Ivor, Wakefield, Waverly and Disputanta along the famous 52-mile tangent railroad tracks (now part of Norfolk Southern) engineered and built by her husband between the cities of Suffolk and Petersburg.
