Origin of the Name Thisiayanvillai:
This name consists of two words..Thisaiyan and Villai (Villa is a farm house in Latin and Vilai is a Farm land in Tamil). There are records available to show how this village derived its name from the book written by Alex Cruz Muthiya “MANA VEERA VAZHANADU”. Manavazha Veera Nadu was one among the five vazhanadus of the late Pandiyas. The last ruler of Manaveeravazhanadu was one (Manatachia alais Aabathukuthai) meaning (savior at the dead the end). along with other few chieftains. He ruled the Manaveeravazhanadu along with four other valzha nadu kings. After their demise they have seen worshiped by locals as deities (Anju Veetu Samy). The ruler had his capital at arasoor as the domicile of the kings.
Near the kings residence at arasoor there were quarters of the warriors (in Tamil they are known as kavalars). They defend the country from the four corners that is the four directions east, west, north and south. Therefore their living place was called as Tisai kavalar villai. That means form land of warriors of four directions. To prove this there are evident hamlets at the four corner of Tisaiyanvilai. They are kiraikaranthattu, mottainthattu, idachithattu pallanthattu at north, west, east and south respectively. The thattu in Tamil denotes the English word plate or watch tower. From the four hamlets it can be assumed that there were the watch towers of the kavalars is of mana veeru vazha nadu at Tisaiyanvilai and made it to be called as thisai kavalr vilai. Hence the town Tisaiyanvilai was once called as Tisai kavalar villai and by colloquial words it was later turned into Tisaiyanvilai (i.e. : Maruvu in Tamil )
