I was expecting a high Y-Haplogroup O (South East Asian - East Asian lineage) among Tamil castes. In my opinion the legend of Kumari Kandam was brought by these people. I was even encouraged by the observation of South-East Asian HLA alleles among Iyers, Nadars of Tamil Nadu. However, no luck. It looks like Y-Haplogroup O is observed only among tribals(who form 1% of Tamil Nadu population). But interestingly they are supposed to be later migrants. The later migrants who became tribals? I'm not really happy with that explanation. I feel something amiss there.
Will they be the first and only West Eurasian Brahmins in India(or predominantly with West Eurasian lineages)? I don't consider any of R1a1, J2, L, H, R2 as West Eurasian. However, R1b is. I suppose all the Haplogroup R1b persons migth have been wrongly identified with R1a(they might have tested positive for M173(R1) and negative for M17(R1a1)).

Konkani Sarawsat Brahmins:
Previously, I have discussed about Konkani Saraswat Brahmins and Kashmiri pundits being the Dravidian priestly class representative in the North-West. They were historically known to be pure Shiva and Shakti worshippers. Since both of them are Indo-Aryans, I have tried to appropriate their surnames to further my claim. The common surnames of Konkani Saraswat Brahmins are;
Kamat, Shenoy, Baliga, Pai, Nayak.
Baliga : From Dravidian word bale = to grow
Find the reference here.
Kamat : From Dravidian word komati = trader
Find the reference here.
Nayak: It's very tricky. You find almost all the Nayaks in South India. This might have Nostratic origins (Find the reference here.) However, I feel Indo-Aryan Nayak might have Dravidian roots. Probably, the highest diversity(I like this argument) of Nayak is found in South India. That might show oldest origins of this word.
Kannada : Nayaka
Malayalam : Nayar
Telugu : Nayudu
Tulu: Nayaka, Nayara, Nanaya
Kannada and Tamil Nayaks look like derived from Indo-Aryan which inturn derived from Dravidian.
Malayalam and Telugu show sound changes in Dravidian context. Malayalam 'ra' - Telugu -'da'
eg: Andagara(Kn) - Andagada(Te)
Shenoy : I think it's original form is Shenawi; the sound change applied here is -w to -y
eg. Brohwi - Brahui
Gowi - Goyi ( A Srilankan caste)
However, I'm not sure of the origins of this word. My friend(a Shenoy himself) thinks it's derived from shANya (jANa(kn) = smart).
Pai: Again this should be Pawi or Pa...wi; No idea about the origins.
Kashmiri Pundits: The surnames Tikkoo, Mattoo look enticing. However, absolutely no idea about their meanings.
