Another great blog regarding Kirat

Kirat-or Kirati- are indigenous Nepalese people of Tibetan stock the southern slopes of theHimalayas extending eastward from Nepal into India, Burma and beyond. Although only thesunwar (the people who inhabit the region westward of River Sun Kosi), Rai (also known as Khambu or Zimdar), Limbu (also known as Yakthumba or Subba), Yakkha (also known as Dewan) and Lepcha (also known as Rong-pa or Lapche) are generally regarded as Kirati, the vast majority of ethnic people of the region eastward of Nepal too address themselves as Kirati.

The original inhabitants of the Doars region of India known as Koche and Meche claim themselves to be Kiratis and so do the Bodo and Kachari tribes of Assam: they derive their titles from the original place of their dwelling, i.e., Koche from the River Kosi, Meche from River Mechi and the word Kachari is derived from Kachar which means river basin. The basis of these claims relies on the fact that they are mongolians even though they distinguish themselves from Mongolians elsewhere. They are therefore often identified as Kirati-Mongolians.
