Derdhe

Overview

Derdhe was a member of the Koude clan in the early Qing Dynasty. Volume 29 of the official Qing Dynasty genealogy, *The Comprehensive Genealogy of the Manchu Clans of the Eight Banners*, records him as a member of the Plain White Banner, originally from the Yehe region. He submitted to the Qing Dynasty at the beginning of the dynasty and served as a military officer. The biography concludes by stating that the family was transferred to the Mongol banner of the same banner. However, the clan's inclusion in the Koude clan and its later Mongol banner classification are not at the same level; one cannot simply erase or change the early clan name or ancestral home based on the phrase "transferred to the Mongol banner."

The military officer was responsible for military duties such as leading and guarding the army. His son, Zhuhe, served as an acting military commander in campaigns in Jiangxi and Huguang, distinguishing himself in Fuzhou and other places, earning the title of Yunqiwei and being appointed as an infantry officer. His eldest son, Ping'an, inherited the title, and his second son, Hedase, also served as an infantry officer. "Acting" indicates being entrusted with a duty; Yunqiwei was a hereditary title, while infantry officer was a military position; the awarding of this title and the appointment of the officer require separate descriptions.

The biography also lists the descendants of Derdhe's elder brother, Ubadai, and younger brother, Agtu, but these are collateral branches and cannot be included among his biological descendants. The historical geographical area of ​​Yehe can be referenced to the present-day Yehe Manchu Town and its ruins in Tiedong District, Siping City, but this is only a modern geographical reference. The specific personnel covered by the reassignment, the organizational structure under the Zhuhe Commission, and the kinship generations of the Wubadai branch are yet to be verified; information on the original genealogical branches of brothers and siblings will be retained.
