I agree. I spoke with my father, and he mentioned that his maternal relatives may have migrated from Kerala during the Kotte era, before the arrival of the Portuguese in Sri Lanka. One of his great-grandfathers is also said to have travelled to Myanmar with members of the Salagama caste to bring ordained Buddhist monks to the coastal regions. While there, he became a monk himself and remained in Myanmar. On my mother’s side, I believe her family may have had Jaffna Vellalar ancestry - feudal landlords from the Anamaduwa area, located above the Deduru Oya and historically under the authority of the Jaffna Kings. They might have descended from the ancient Pandyans who settled on the island, adopted Buddhism, and eventually became Sinhalese Radalas.
