After the demise of Qin, did the Won family perish?

Won, an ancient surname in China, originated from the Boyi family of the ancient Dongyi Group.

During the Xia, Shang and Zhou Dynasties, many nobles were born and many kingdoms, princes and princes were established, and dozens of clans such as Xu, Jiang, Huang, Ge, Zhuge, Lian, Fei, Li, Zhao, Ma and Bai were formed. Among them, Zhao's family was composed of Sheng's family who moved westward, which was built in the Zhou Dynasty of Zhao, Qin and Liang Dynasties. The monarch of Qin and the monarch of Zhao belong to the Zhao family, which won the surname, and can only be regarded as a country that won the surname, not a country that won the surname. They are all from Zhao.

In a word, although the royal family of Qin won the surname, it was Zhao. For example, Qin Shihuang's real name was "Zhao Zheng". With the development of the State of Qin, some new surnames have appeared in Qin Gong, such as Bai, Gu, Liang, Yan and Qin. There are records in the history books, but there is no record of changing the family name to the new family name, which does not conform to the normal evolution law of family names. Therefore, after Qin's death, there was no Won surname in his hometown (Shanxi, Shaanxi and Gansu provinces today), and there was no modern Won surname in these areas until today, which caused the Won surname to be completely annihilated. In fact, after the demise of the Qin Dynasty, although its royal office was purged and suppressed by the later regime, it was far from extinct. Only after the name was unified, it was no longer called Won surname, but directly existed as various clans in the world. Today, Pei, Gu, Liang and some Zhao surnames and Qin surnames are their descendants.

However, China still has a won surname, but it is not the Qin royal family, but a person who has not been gentrified in the won surname of the ancient Dongyi Group (as evidenced by living mainly in East China today). Because they never became a clan, they can change their surnames directly from their surnames. There was a man named "Won Gong" in Historical Records at the end of the Western Han Dynasty.
