zhòng sūn 仲孙

Migration and Distribution (Lack of information) The Zhongsun surname is not listed among the top 100 surnames in the Mainland and Taiwan. "Zhong" means "the second son". In ancient times, the second - born sons often had the character "Zhong" in their names (the eldest usually had "Bo", and the third and fourth sons often had "Shu" or "Ji"). It is said that among the descendants of Xi Zhong, there was a person named Zhong, and his descendants took Zhongsun as their surname. During the Spring and Autumn Period, Qingfu, the son of Duke Huan of Lu, whose style name was Gongzhong, was also known as Mengsunshi and also styled Zhongsunshi (therefore, his descendants had two branches, namely Mengsunshi and Zhongsunshi). This way of addressing was to show respect for Duke Huan of Lu as a descendant of the royal family. Also, there was Duke Zhuang of Song, and one of his sons had the style name Zhong, and there were also descendants who took Zhongsun as their surname because of him. In addition, a small number of people with the Zhongsun surname are descendants of Zhong You, a disciple of Confucius. The prominent families of the double - barrelled surname Zhongsun are from Gaoyang Commandery (in the northwest of present - day Zibo County, Shandong Province).
