Mount Lebanon History

Mount Lebanon is spread across more than six square miles of Western Pennsylvania’s hills, but it once was contested land.Surveys were made on May 25, 1770, for James McFarlane’s “Black Oak Hill” within what was to become Mount Lebanon and a neighboring tract, probably now in Dormont, occupied by an individual named Price. A Pennsylvania patent for the McFarlane land was not received until November 27, 1788, perhaps because Virginia had included this territory in the western part of its County of Augusta and, later, the County of Youghioghenia.
