Jean Libbera (1884 - 1936), AKA "The Double-Bodied Man," had his brother, Jacques Libbera, connected to his from his chest-stomach area. He was born in Rome. The parasitic twin was alive and could move as well. An X-ray showed that there was a head embedded within Jean with a circumference of about six inches. He got married and had four normal children.
