The story

from WikipediaRead it all ↗

Mount Oliver was first settled by John Ormsby, an officer in the command of General Forbes, who was granted 249 acres of land along the banks of the Monongahela River. In 1788 Allegheny County was divided into townships, with Ormsby's plot being part of St. Clair Township. In 1800 Ormsby began selling parcels of land, while retaining rent and property taxes from residents. Ormsby named his growing settlement Mount Oliver, after his son, Oliver Ormsby. Later that year St. Clair Township would be divided with residents attempting to incorporate as a borough, however, the state ruled against the effort stating that the property owner quota was not sufficient to award incorporation, and Mount Oliver would become part of Lower St. Clair Township.
