Here is the picture of still existing people of Kumaun( Garwahl). While now they may have migrated from other places! They look very Nepali to me. Perhaps, the term "Kumaii" described for a certain type of a brahmin caste could be derived from priest and scholars who migrated from Kumaun(Garwahl). Modern day Kumaun is locatd in Nainitaal, western border of Nepal. If the Bristish didn't come inbetween the Gorkha Invasion, Nepal would have taken over the place anyway and I would have still been a Nepali. Perhaps, the "Sahs" and "Thapas" also could have come in power in Nepal from this migration along with Kumaii Brahmins. Peace, RubiesDiamonds
