"This posting is only for educational purpose only, I have nothing to do with caste thing. " Dalli Resham, You are always bahun, but your kids will not be bahun. If upadhyay bahun married an upadhyad girl without vedic rites, kids from them will be called jaisi bahun. (without vedic rites means marrying a widow or divorced.) If someone give a birth before marriage, that is also against of vedic rite. If Upadhyay bahun married jaisi bahun, kids from them will be jaisi bahun. If upadhyay bahun married chettri, mager, gurung, rai, limbu, newar, they are gonna be chettri even though they will carry last name as bahun's but still they would be chettri or so. Thats all I know.. If you married other than nepali, like american... there is no caste to call in nepal, only amricane nepali. if bahun gal goes to newar guy = kids will still the newar identity, still they are mixed. if bahun guy marry newari gal = kids will be chettri. Like i said above, this is only for the educational purpose. I knwo, if you guys go back to nepal, your parents would still prefer you to get married with your own caste. So that, it's better to know about what's nepal caste is all about.
