This essay analyzes the development of the Zheng clan, one of the most influential clans in southeastern China during the Ming-Qing transition. It attempts to understand the reorganization of this clan, which not only belonged to one of the Eight Banners but was also an important Chinese lineage itself during the Qing period. After Zheng Keshuang surrendered to the Qing Empire, his family were recruited into the Eight Banners system and remained as Beijing bannermen until the collapse of the Qing. The Zheng clan’s hometown, Quanzhou, is regarded as one of the areas where the Chinese lineage system was most developed. This study therefore analyzes ten volumes of the Manchu language Niru and four Chinese genealogies in order to understand the Zheng family as bannermen in Beijing as well as the Zheng Chinese lineage in Quanzhou. Through such analysis, this study attempts to comprehend the interaction and association between family and lineage, hoping to provide a deeper understanding the Zheng clan during the Qing period.
