About Galo community
At about 1.5 lakh people, the Galos are one of the 26 major communities of Arunachal Pradesh, and dominate West Siang, Lepa Rada and Lower Siang districts. They have a big population in East Siang, Upper Subansiri and Namsai districts too.

The Galos belong to the Tani group inhabiting Assam and Arunachal Pradesh, besides Tibet.

They trace their common origin to a primeval ancestor, Abotani.

How are the names recorded?
Galos maintain genealogy through given names. They have a system of prefixing the second syllable of a father’s name to that of a son, who passes on the suffix in his name to his son. They can trace the names of ancestors from the first syllable or prefix of our names.

Mr. Bagra, who began record-keeping 20 years ago, has created a genealogical site, with some names hyperlinked. Mr. Bagra’s father, at number 20 on the Memo line, is Gumken, his grandfather is Megum, and his great-grandfather is Gumme. The ‘me’ in his great-grandfather’s name was prefixed to his grandfather’s name, whose suffix decided his father’s name.
