One of those Central Asian immigrants to Korea originally came to Korea as an aide to a Mongol princess who had been sent to marry King Chungnyeol of Goryeo. Goryeo documents say that his original name was "Samga" but, after he decided to make Korea his permanent home, the king bestowed on him the Korean name of Jang Sunnyong. Jang married a Korean and became the founding ancestor of the Deoksu Jang clan. His clan produced many high officials and respected Confucian scholars over the centuries. Twenty-five generations later, around 30,000 Koreans look back to Jang Sunnyong as the grandfather of their clan: the Jang clan, with its seat at Toksu village.
