It is widely believed that the present Rajopadhyaya Brahmins are the descendants of those immigrant groups. Similarly, Madhesi royal clans including Malla themselves and their courtier castes like Kayastha, Hada, Chauhan, Chandel, Vaidhya, Rajput, etc. migrated into Kathmandu Valley in the 14th century and ruled as Malla kings and their nobility, who have since coalesced to form the current Chatharīya (Kshatriya) caste. Historical records also show trading, service, and untouchable clans of the Indian plains immigrating to Nepal Valley along with the entourage of the Maithil and Malla kings, and in due process, becoming Newars themselves. Some of them includes Dusadh/Podhya, Jogi/Jugi/Kapali, Dhobi/Dhobi, Mali/Mālākar, Halwai/Rajkarnikar, Teli/Manandhar/Sāyami, Kumhar/Kumhā/Prajapati, Chamar/Chyamah, among others. For Newar Brahmans, "Khae" Bahuns and Chetris are only water-acceptable. The Chatharīya and Pañcthariya accept water and all foods except boiled rice and lentils from them. Jyapu and lower clean occupational groups accept water as well as boiled rice and lentils from them. Conversely, those Khas groups untouchable to the upper Khas groups themselves are also untouchable for the Newars. The Sae(n) were generally treated as water-unacceptable by Brahmans. The Chatharīya and strict Pañcthariya accepted water (but not boiled and salted foods) from them. Most, but not all, Jyapu accepted all food except boiled rice and lentils from them. The residual group, neither Khae(n) nor Sae(n), are Muslims and Westerners and these are generally treated as untouchable by the highest levels, and water-unacceptable by those below them. For the higher Parbatiya castes (Bahuns and Chetris), the highest twice-born Hindu Newar castes (Brahmans and Chatharīyas, and sometimes Pañcthariyas) exist in a kind of "separate but parallel" status of Tāgādhāri with respect to the high caste Parbatiya.
