In regard to the successors of the abbot of the Ḥbri guṅ pa, descriptions are given in Deb gter sṅon po (Blue Annals) and Deb ther dmar po gsar ma (Red Annals). Neither of them, however, provides us with a sufficient explanation of the kinship which existed among these abbots. Professor G. Tucci studied the Vth Dalailama’s Chronicles and compiled a genealogy which he published in his book Tibetan Painted Scrolls, Genealogical Tables, 1949. The author of the present article notices that in many respects there are discrepancies in Professor Tucci’s work. He makes a study of the Mkhas paḥi dgaḥ ston, the Tibetan history written by Dpaḥ bo gtsug lag in the 16th century, and edits a more detailed genealogy of Ḥbri guṅ pa. He also refers to the Ming shih lu 明実録 in order to check the accuracy of the descriptions given in the Mkhas paḥi dgaḥ ston.
