Over time, Willoughby sent citizens into every major U.S. military conflict. Several memorials and historical relics are displayed in Wes Point Park, the center of downtown Willoughby, to honor those that have served. Willoughby’s first permanent settler was David Abbott in 1798, pre-dating Ohio’s bid for statehood by five years. Abbott and his family had close relations to the local tribe of Erie Indians along the banks of the river the Indians called the "Sha-ga-rin" or Clear Water. This river was later called the Chagrin River, though the derivation of the name remains in dispute. Willoughby is a city in Lake County, Ohio, United States. It is a suburb of Cleveland, Ohio. The population was 22,621 at the 2000 census. Willoughby is served by a branch of the Willoughby-Eastlake Public Library.
