 The Siwanoy, an Agonquian-speaking sachemdom (or subtribe) of the Wappinger tribe, originally occupied Darien and the surrounding area.The Siwanoy controlled what is now much of the Bronx, Westchester County and the Connecticut "panhandle" as far east as Norwalk and part of Wilton.The land that became Darien was a part of Stamford from the time Stamford was bought from the Indians until Darien was incorporated as a town in 1820.
