Margaret and Mary Gibb (1912-1967) were among the first women in the United States to survive a natural birth of conjoined twins; they were joined at the hip and shared no major internal organs. At age 16 they left home to join a vaudeville act, and toured internationally with the Barnum and Cole Brothers Circuses as 'America's Siamese Twins' during the 1930s.
