The main line of descent traditionally held the title of Duke Yansheng, which was changed to the title of the first Sacrificial Official to Confucius in the 20th century. This title is currently held by Kung Tsui-chang.

Kong may also be the English transliteration of a rare Chinese surname 空, or a less common form of the Gong surnames such as 龔, 貢 and 弓.
