Chozhia Vellalar
Sozhiya Vellalar (also known as Sozha Vellalar) is a land-owning upper caste from the Indian state of Tamil Nadu. The Sozhiya Vellalar caste consists of 4 subcastes, namely Sozha Vellalar, Vetrilaikkarar, Kodikkalakarar(Kodikkal Vellalar) and Keeraikarars. Origin. Sozhiya Vellalars were the chieftains and land-owning agriculturalists of Chola dynasty. They use the title Pillai and Mudaliar. The term "Pillai" literally means "child" in Tamil language. Tamil inscriptions of ancient Sangam era define the direct meaning of Pillai as "Child of King" (prince), denoting nobility. This is due to the fact that Sozhiya vellalars held important positions in the  king's administration, mainly for their skill with numbers, maintaining treasury and accounts. The term "Kanakku Pillai" (Kanakku meaning Mathematics, in other words, numbers) originates from the fact that Pillai caste people were the record keepers or treasurers for kings. Distribution and migration. The Sozhiya Vellalars were present predominantly in the delta districts of Tamil Nadu - Trichy, Thanjavur, Karur, Namakkal, Mannargudi, Nagappattinam. Nowadays they are present in almost all the districts of Tamil Nadu. Though the distribution of the community is found in most of the districts, they migrated to the other parts of Tamil Nadu from Trichy and Thanjavur  areas towards the middle and second half of the 19th century. As they moved in, they always followed the river bed areas for settlement. Thus, the said community when came to Salem District they initially settled at Palamedu. When their life at Palamedu became difficult due to Theechati Kolliyars (Dacoits with fire) they moved out. Of these the persons who moved to Pandamangalam area were farmers and the traders moved into Proper Salem. They settled as trader dealing in betel leaves and thus earning the name Vatrilaikarar. Sri Lanka. The Vellalars of Sri Lanka have been chronicled in the "Yalpana  Vaipava Malai" and other historical texts of the Jaffna kingdom. They form half of the Sri Lankan Tamil population and are the major husbandmen, involved in tillage and cattle cultivation. Local Sri Lankan literature, such as the "Kailiyai Malai", an account on Kalinga Magha, narrates the migration of Vellala Nattar chiefs from the Coromandel Coast to Sri Lanka.The Kings of Jaffna married among the Vellalas.
