Violet and Daisy Hilton were conjoined twins sharing a common blood and nervous system. They were sold by their impecunious mother to a midwife, who greedily took advantage of their misfortune; while they sang, danced, played instruments in circus sideshows, their veritable slave-owner kept all their earnings and forbade them from socializing. Eventually a lawyer helped them escape and even reacquire money they were swindled out of. They went on to do movies (including 1932’s Freaks).
