Information: The first known inhabitants were the Mound builders. Two of their mounds were flooded by the creation of Pymatuning Lake. The Lenape were living in the area when European settlers fist came there. The lake is named for the chief who lived in the area at the time, Pihmtomink. The Lenape were pushed out of the area by the Seneca tribe, a member of the Iroquois Confederacy. The Seneca were defeated by General Anthony Wayne's forces during the Northwest Indian War and left the area under the terms of the Treaty of Greenville. This treaty marked the end of Native Americans inhabiting the area. The first settlers to the area were farmers, whose life was not easy as the land was very swampy and very difficult to reclaim. Farm animals that wondered off were often lost in the quicksands of the swamp, or fell prey to predators like foxes, bears and mountain lions. The swamps were infested with mosquitoes that brought yellow fever to the settlers.
