A History of the Town of Sullivan, gf, 1777-1917 by Josiah Lafayette Seward published by Sentinel Printing Company, 1921
           
          Stephen Griswold was probably the first settler of Sullivan He lived at the site of  the later house of the Lockes, at 102. He must have settled there as  early as 1768, having been the drawee of the lot upon which he settled.  Benjamin Olcott came the same year to what is now the town farm, and  lived at the site of 68. They were the first two families in town, and  evidence seems to make it probable that the Griswolds preceded the  Olcotts. Mrs. Griswold's first name was Hannah. We know no more of her.
