The Bunker brothers were born on May 11, 1811 in Siam (now Thailand), in the province of Samutsongkram, to a fisherman and a mother (Nok or Nak] in Thai). They were joined at the sternum by a small piece of cartilage. Their livers were fused but independently complete. Although 19th century medicine did not have the means to do so, modern surgical techniques would have easily allowed them to be separated. In 1829, they were "discovered" in Siam by British merchantRobert Hunter and exhibited as a curiosity during a world tour. Upon termination of their contract with their discoverer, they successfully went into business for themselves. In 1839, while visiting Wilkesboro, North Carolina, the twins were attracted to the area and settled on a 110 acre farm in nearby Traphill, becoming naturalized United States citizens.
