Nonsense..Seems you dont know history..It was called Madraspatnam (where people lived, named after a cowherd Madarsan) and another area (barren land gifted by Chennakesava Nayak, hence the name) was called Chennapatnam. You have many 'Ashok nagar"s in India named after the great Ashoka .Does it mean they all belong to Biharis ? Also almost all villages that were part of Madras city and older than the city itself have genuine tamil names e.g., thiruvallikeni, thiruvanmiyur, mylapore, ezhumbur(egmore), thiruvotriyur..and many like these. Historically the area has been under the tamil region of Thondaimandalam, if you didnt know. Ofcourse there were large number of telugus since it was the capital and hence people migrated from the andhra and rayalseema regions. But the language of the city has always been tamil. If tamil leaders really had that much clout Tirupathi also would have been part of TN. It is part of TN because it was prodminantly a Tamil city.No other reason.
