Founded in 2003, the Dashwood Historical Society documents the lives of the Dashwood family and their extended, and extensive, kin. The Society is located in historic downtown New Salem, a western outpost of the greater Quabbin metropolitan region. The centerpiece of the DHS are the papers of distinguished historian I. Eliot Wentworth, the three Dashwood sisters: the pathbreaking molecular evolutionary biology N. Eleanor Dashwood, the theoretical astrophysicist Marianne Dashwood, and archaeologist Margaret Dashwood.
