The primary goal of the present essay is to introduce the value of two rather different texts for the study of Manchu history. One is the so-called Jade Registers, which recounts the genealogy of the Ch’ing imperial family. The other is a work known as the Hsin-y□an chi-ch’ing. Because both texts record the marriages of both male and female members of the Ch’ing imperial clan and also identify the clan from which each member’s mother is descended, they provide a relatively comprehensive account of the marriages between the imperial and banner families, as well as the marriage alliances between the imperial clan and the various Mongol tribes. Takes together, they provide a wealth of systematic biographical detail which can be used to supplement and correct the historical records.
