The character for the Kong surname was derived from the Zi (子) family name. The founder of the Shang Dynasty, Tang of Shang whose family name was Zi, had the courtesy name of Taiyi (太乙). His descendants fused the character Zi (子) to Yi (乙), forming the character Kong (孔) which eventually became a surname. It first appeared during the Zhou Dynasty as the courtesy name Kongfu (孔父) of a noble in the State of Song named Jia (嘉), said to be a descendant of the Tang of Shang. Kongfu Jia was murdered, and his son escaped to the State of Lu where he adopted Kong as the name of his clan. His family settled in Qufu and Confucius was one of his descendants.
