Tulu
Shivalli Brahmins living all over the Indian state of Kerala are part of the larger Tulu Brahmin subsect primarily found in the Indian state of Karnataka but also in the Kasaragod district of Northern Kerala. Their mother tongue is the Dravidian Tulu language. Brahmins from Tulunadu may have migrated to Kerala before the first century C.E. Today, there is a sizeable Tulu Brahmin population in Thiruvananthapuram and elsewhere in the state.
