Lineage of Ato Bogum through sub-clans across Arunachal Pradesh
The Bogum sub-clans trace their ancestry through Ato Bogum's sons — Gumdin, Gumle, and Gumi — settling across Arunachal Pradesh over generations.
Ato Bogum had five brothers: Boh, Boka (Bakang), Botu, and Bomi. He had two wives: Yakam and Ribo, from whom were born three sons — Ato Gumdin, Gumle, and Gumi — and one daughter, Gumne. The Bogum sub-clans descend from these lineages. The Foundation is one of the largest clan-based organizations of the Galo Tribe in Arunachal Pradesh.
From Nyik-Artu, the Bogum clans gradually dispersed across present-day Aalo, Kombo, Tadin, Darka, Liromoba, Kamba, Nikte, Basar/Dari, Gensi, Likabali, Kangku, Nari-Koyu, and surrounding areas. Some Bogum clans continue to reside in Upper Siang and East Siang districts from time immemorial.
