Lupel (klu 'phel) was the son of Lhuntub (lhun thub), the sixth king of Derge (sde dge). He had five brothers and one sister. The brothers were named Kunga Gyatso (kun dga' rgya mtsho), who was also known as Derge Lama (sde dge bla ma), Jampa Puntsok (byams pa phun tshogs), Lama Lhasung (bla ma lha srung), Ponchen Karma (dpon chen karma), and Karma Samdrub (karma bsam grub). The first three brothers ordained. Jampa Puntsok, who was the de facto ruler of Derge, greatly expanded the royal monastery of Lhundrubteng (lhun grub steng) and the territory of the kingdom.
He fathered at least three sons with two wives. Orgyen Tashi (o rgyan bkra shis) became the eighth king of Derge and the leader of the family in the thirty-eighth generation. Kunga Puntsok (kun dga' phun tshogs) is considered to have been the first abbot of Lhundrubteng, taking over administration after his uncle Jampa Puntsok passed away. A third son, by a second wife, Sanggye Tenpa (sangs rgyas bstan pa) served as the third abbot of Lhundrubteng.
