Although Chinese make up the largest part of America's Asian and Pacific Islander population, none of the romanizations of 沈appeared among the 1000 most common surnames during the AD 2000 US census.
As is common with Chinese surnames, the modern Shen family arose from various unrelated sources.
One origin traces it to the Shen (沈) kingdom in Runan County, Henan. These people were descended from Shao Hao, whose grandson was Zhuanxu's teacher and fathered Yun Ge and Tai Dai. Tai Dai was granted Shanxi for his achievements in controlling the flooding of the Yellow River and his descendants divided into four "kingdoms": the Shen, the Yi, the Ru, and the Huang. Electing not to participate in the northern kingdoms' campaign against Chu in 506 BC, Shen was invaded and destroyed by Cai. The rulers and vassals of the former state then bore the clan name Shen to distinguish themselves.
Another group descended from the rulers and vassals of the revived state of Shen after King Cheng granted it to the Zhou prince Ran Ji for suppressing the rebellion following the death of his brother King Wu.
A third group derived from the Mi (芈) family of Chu during the Spring and Autumn Period. Chu had conquered the area of Shen and, in 506 BC, its governor was Shenyin Shu – a Chu field marshal from a cadet branch of the royal house. He was killed in the Battle of Boju that year, opposing a Wu invasion led by Wu Zixu and Sun Tzu. In his memory, some of his descendants and vassals adopted the clan name Shen for his fief, while others became the Ye after the fief granted to Shenyin Shu's son Shen Zhuliang, better known as the Duke of Ye (葉公, Ye Gong).
The You clan (尤) is said to be a branch of the Shen clan, having simply removed the side-water radical 氵 from their surname sometime in the 10th century due to conflict with a different Shen (审) ruling family in Fujian Province. Owing to this, the You and Shen continued to be unable to intermarry, just as if they were still a single clan.
