Mengguozi Clan (Transliteration Provisional)

Overview

The Mengguozi clan is a Manchu surname recorded in Volume 62 of the *Comprehensive Genealogy of the Manchu Clans of the Eight Banners*, an official compilation of the Qianlong Emperor's reign. The genealogy states that the family resided in the Suifen region and was listed among the rare surnames in the Plain Blue Banner. This entry begins with Bai Xin, noting his submission to the Qing dynasty at its beginning. His great-grandson, Sergude, served as a zuoling (military officer), and Yong Guoerde served as a Xiaoqi Xiao (military officer). His great-great-grandson, Serden, served as a third-class guard when the genealogy was compiled.

The Plain Blue Banner was one of the Eight Banners. Banner registration was related to both military service and household registration. A zuoling was an official responsible for the basic organization and management of the Eight Banners; a Xiaoqi Xiao was an officer in the Xiaoqi organization, responsible for the training and leadership of the soldiers in their zuoling. Therefore, the positions held by the two great-grandsons reflect different roles in basic military and political management.

Serden's third-class guard position belonged to the guard system of princely residences, differing in status and duties from the emperor's guards. "Third-class" refers to an internal rank within the guard system, not that he was a third-rank official in the Qing dynasty. In genealogy records, "great-grandson" usually refers to a great-great-grandson, one generation removed from a great-great-grandson. This record connects the ancestors' allegiance with the descendants' official appointments, but does not record that Bai Xin himself held the aforementioned military position. The specific ancestral residence location and variant characters of the name of Sui Fen still need to be verified against the original printed edition; the original entries are retained for now.

The romanization of the unusual initial character in the recorded clan name is provisional and should not be treated as an attested Manchu spelling.
