Ancestral worships in the Shang period were not only practiced by royal kings in royal temples, each royal clan or royal family also had its own temples dedicated to the ancestors of their own lineages. This paper carried out a textual analysis based on the 11 oracle bone inscriptions that documented sacrificial events in temples and belonged to the so-called ’royal-family groups’. The author argues that two locations in Yinxu might be related to clan temples. One is the F29 in Xiaotun, which might belong to a Zi lineage associated with the royal king. The other one is F22 in the C cluster of architectures in Dasikong village, which might belong to the Mawei clan.
