huán 桓

### Migration and Distribution (No information available) The surname Huan is not ranked among the top 100 surnames on the Chinese mainland or in Taiwan. The Huan clan ranks 407th in the Song edition of the "Hundred Family Surnames", and its place of origin is the Qiao Commandery (present-day Bozhou County, Anhui Province) during the Han Dynasty. There are four origins of the Huan clan: 1. It comes from the Jiang surname. According to the "General Annals of the Clans and Surnames in the Comprehensive Gazetteer", during the Spring and Autumn period, Prince Xiaobai, the younger brother of Duke Xiang of Qi, fled to the State of Ju. After Duke Xiang was killed, Xiaobai returned to the State of Qi to ascend the throne. He appointed Guan Zhong to carry out reforms and became the first of the Five Hegemons in the Spring and Autumn period. After his death, he was posthumously titled "Huan", known as Duke Huan of Qi. His collateral descendants took the posthumous title as their surname and were called the Huan clan. One branch descends from Duke Huan of Qi. 2. It comes from the Zi surname. Xiang Gui, a collateral descendant, took his grandfather's posthumous title as his surname and was called Huan Tui. 3. It is simplified from the "Huan Hou" clan. During the Zhou Dynasty, there were Marquis Huan in the States of Jin (with the Ji surname), Qi (with the Si surname), and Cao. Their descendants had the "Huan Hou" clan, which was later simplified to Huan. 4. It is from the Xianbei ethnic group who came to China during the Northern and Southern Dynasties. As recorded in the "General Annals of the Clans and Surnames in the Comprehensive Gazetteer", the descendants of Duke Huan of Qi took the posthumous title of Duke Huan as their surname. The descendants of Duke Huan of Song also called themselves the Huan clan. In addition, the Wuhuan clan of the Later Wei also changed their surname to Huan. Moreover, both the "Yuanhe Compilation of Surnames" and the "Book of Wei - Records of Official Titles and Clans" have texts verifying the origin of the Huan clan. It can be seen that among the ancient Huan clan, there are descendants of Jiang Taigong from Shandong, descendants of King Tang of Shang originating from Henan, and also a small number of descendants from the Xianbei ethnic group. The prominent family is based in the Qiao Commandery (present-day Bozhou County, Anhui Province).
