Lha-bzang Khan
Amursana was born in 1723 to a noble mother from the Dzungar-Oirat tribe and "taisha" or crown prince of the Khoit-Oirat clan. Amursana's mother, Boitalak () was the daughter of Tsewang Rabtan, leader of the Dzungar-Oriat tribe following the death of Galdan Boshugtu Khan. She first married Danjung (), the eldest son of Lha-bzang Khan, ruler of the Khoshut-Oirats tribe. Following Danjung's death c. 1717, allegedly at the hands of his father-in-law, Boitalak married Amursana's father, a "taisha" or crown prince of the Khoit-Oirat clan.
