Gombu was born in the Kharta region to the north-east of Everest. His early life was marked by the complexities of his parents' marriage. His father, Nawang, was a monk, the younger brother of the local feudal landowner. His mother, Tenzing's beloved older sister, was Lhamu Khipa, a nun from a family of serfs. The two eloped, causing a scandal, and for a time they lived in Khumbu, a Sherpa district on the other side of the border in Nepal.
