The area of land along the West Branch and Larrys Creek was previously known as "Level Corner". Many of the early settlers were attracted to this area of fertile farmland. Isaac Smith migrated to Piatt Township from Chester County. Smith was a millwright and farmer. Robert Covenhoven was another prominent early settler. He was a veteran of the American Revolution, having fought at the battles of Trenton and Princeton. Covenhoven had returned to the West Branch Valley just before the Big Runaway. Upon hearing of the approaching raiding Indians and Loyalist, Covenhoven rode west along the ridge of Bald Eagle Mountain to warn settlers at Fort Antes (opposite what is now Jersey Shore) and the western part of the valley. Covenhoven is listed as a Fair Play Man and one of the signers of the Tiadaghton Declaration of Independence. Following the Great Runaway, Covenhoven continued to serve as a scout for the Patriot forces on the Pennsylvania frontier. At the conclusion of the war he settled with his wife at Level Corner. They raised a family of three sons and five daughters. Covenhoven lived to the age of 90 and is buried in Northumberland, where he went to live with his daughter Nancy after his wife Mercy's death.
