Well the whole theory about the nayars being of newar origin is actually written by a newar so it makes sense how they came up with the idea. ANd i don't believe keralites were newari coz its just absurd. In my distant faimly I have a relative that is married to a nayar brahmin, and looking at them whole relatives, none of them look chinese looking. IN onclusion i would just liek to say that, Newars are skeptical about everything, like where they are from. So obviously if you dont even know where ur from, your gonna make stupid theories and make up places you would come from. Like some say there are from rajesthan, because there is a place in rajesthan called MEWAR. WHOOOPIIEE just coz theers a place that is similar to the name doez that mean they are from there. For instance, there is a place called DHARAN in Saudi Arabia, and there is also another place called DHARAN in nepal, does that mean saudis came and established dharan in nepal??? Listen no matter how much you justify that newar brahmins are of indian origin, I would say, by just looking at them having chinkie features and their language being of SINO TIBETIAN, I would just flip my middle finger and say "YEAH THIS IS BRAHMIN TOO". Like i said earlier, brahmin is a preistly caste, so in sanskrit if you are a ethnic group from a preistly "caste" then the sanskrit root "BRAHMIN" can be implied, but you can not be a Hindu Brahmin of indian origin. First of all like you said before, newari brahmins don't keep their gotra? I've never really heard that in brahmin tradition, to prove that you are brahmin, you need your gotra. I mean look at any hindu marriage, the preist needs to know your gotra. And there are like 8 rishis the gotra follows from, and i know defentatly not one of them where chinkies. Peace
