Traphill, North Carolina, United States by nolan The Original Siamese Twins Eng and Chang Bunker, originally from Siam (now Thailand), are probably the most famous set of conjoined twins in history, mainly as they were the source of the term, "Siamese twins'. After touring the world as a circus attraction, they decided to settle down. They built a large house in Traphill, NC in Wilkes County, just a few miles from where my high school would be built. Eng and Chang married a pair of sisters, Eng to Sarah Yates and Chang to Adelaide Yates. Between the the two couples, they had 21 children.
