An Analysis of the Origins of the Xi Surname and Clues to Its Local Branches

The existing accounts of the Xi surname’s origins mainly fall into three categories: descendants of an ancient kingdom, the simplification of the compound surname Ximen, and surname changes made to avoid calamity. There are also generation-name sequences and migration memories from areas including Anhui, Henan, Hebei, and Shandong. Most of these accounts are genealogical narratives or orally transmitted clues and cannot yet be used to merge lineages. Each branch still requires separate verification against genealogies, local gazetteers, inscriptions, household registers, and other documents.

The origins of the Xi surname appear, in the existing surname materials, to have multiple sources. Three explanations are relatively common. One holds that it is connected with the ancient Xi Kingdom or Xiling Kingdom, whose inhabitants later adopted the kingdom’s name as their surname. Another traces it to the compound surname Ximen, with some descendants simplifying it to Xi and identifying Ximen Bao, an official of the State of Wei during the Warring States period, as an ancestor. A third holds that some members of the Zhang clan changed their surname to Xi after dispersing in different directions to avoid calamity during the Ming dynasty. These accounts differ in when they took shape, where they were transmitted, and the evidence supporting them. For now, they should be regarded as origin clues preserved by different families, rather than as proof of a common origin for all people surnamed Xi.

There are family accounts in the Mianchi area of Sanmenxia, Henan, concerning descendants of Ximen Bao who changed their surname. However, establishing that the compound surname “Ximen” evolved into the single surname “Xi” requires evidence from specific genealogies, including records of the founding ancestor of the migration, the person who changed the surname, and the succession across generations. Historical figures may form an important part of family identity, but a continuous lineage cannot yet be established solely on the basis of similar written surnames or orally transmitted relationships.

Memories of surname changes made to avoid calamity are found mainly in materials from Hebei, Shandong, and other areas. Some accounts concern descendants of the Zhang clan adopting the surnames Dong, Nan, Xi, and Bei, while a Shandong family is also said to have described itself as “one family of Zhu and Xi.” A story transmitted by one branch in Anyang, Henan, is associated with court upheavals at the beginning of the Ming dynasty. The people and periods involved in these versions are not entirely the same, suggesting that they may belong to family memories from different regions or may have blended through long-term oral transmission. Verification should examine local old genealogies, tomb inscriptions, ancestral-hall inscriptions, contracts, and local gazetteers separately. Similar stories should not be treated as evidence of common ancestry.

Local generation-name sequences provide a more concrete starting point for identifying branches. Materials from Dangshan, Anhui, record the sequence “Chao, Guang, En, Guang, Da,” which was arranged after the original genealogy was lost. Lingbi, Anhui, preserves the sequence “Jing, Wen, Shi, Xiu, Ji, Jin, Ru (or Ru), Xue, Chuan, Zong, Zhong, Cheng, Yong, Shou, Qi, Xiang, Ke, Da, De, Sheng, Nai, Jiu,” although the written form of “Ru” still requires confirmation against the original document. Anyang, Henan, has a transmitted sequence of “Feng, He, Wen, Zhen, Min.” The sequence recorded in Jiaxiang, Shandong, is “Feng, Xi, Xiao, Bao, Deng, Ting, Xian, Wen, Ying, Guang,” and it is said to have reached the generation name “Ying.” Shared generation names may reflect a connection, but they may also be coincidental and must be assessed together with ancestral residences, marital relationships, and the dates of each generation.

In terms of geographical distribution, existing clues mention Dangshan and Lingbi in Anhui; Mianchi and Anyang in Henan; parts of Hebei; and Jiaxiang and Xijia Village, Daozhuang Town, Guangrao County, in Shandong. There is also a claim that some Xi families in Northeast China are connected with population migrations from Shandong in modern times, but clear information about the founding migrant, place of departure, and date of migration is still lacking. Local gazetteer databases can be used to search for changes in village names, population movements, and biographical records. Online genealogies are suitable for organizing the genealogy pages, generation-name sequences, and migration information preserved by different families by generation, making it possible to identify points that corroborate one another or clearly conflict.

Research into the Xi surname should begin with the most recent several generations of one’s own family. First record ancestors’ names, courtesy names, spouses, burial places, villages of residence, and directions of migration, then gradually trace the line backward. Stories of avoiding calamity, migration routes, and kinship terms in family memoirs should be preserved in their original form, together with the name of the narrator, the date of recording, and the degree of reliability. A specific ancestor and branch relationship should be confirmed only when genealogies, local gazetteers, inscriptions, and other historical documents form a continuous chain of evidence. Sharing a surname does not necessarily mean sharing common ancestry, and Xi families in different places should not merge their lineages merely because they share a particular legend.

In addition, the Qinghe Hall and the commanderies of Qinghe, Pingyuan, and Henan recorded in the existing Bai Clan archives belong to Bai Clan materials. They are not associated with the Xi surname and cannot be used to supplement the Xi surname’s ancestral hall name, commandery affiliation, or lineage. At present, there is insufficient evidence to confirm ancestral hall names associated with the Xi surname, so no unified summary should yet be made.
