Drawing on stele inscriptions in a Yuan-period ancestral graveyard, this article aims to shed light on the emergence and evolution of a Chinese office-holding family in North China under Mongol rule (thirteenth- to fourteenth century). Tracing the family's connections with Mongols, it argues that adaptation to the Mongolian patronage system was essential to obtaining and maintaining political status during the Yuan, and that the kin group was stratified with the patronized descent line monopolizing political privilege. In doing so, the article highlights the value of stone inscriptions in clarifying official status, patronage, and inheritance rights in North China during the Yuan period.
