History

Plum Township was founded on December 18, 1788, as one of the original seven townships of Allegheny County. It originally extended as far south as Versailles (modern-day North Versailles Township), east to the county line, west to Pitt Township, and north to the Allegheny River. Plum has shrunk greatly over the years in area, but still remains among the larger municipalities in Allegheny County.

The 1889 history of Allegheny county, Pennsylvania, describes the township as having “no villages of importance”, but listed the first postoffice, Antrim, 1840–1857; New Texas, a hamlet, in the geographic center of the township with “the usual mechanics, local stores, etc.”, post office from 1856; and Logan’s Ferry, on the Allegheny River and Allegheny Valley railroad, in the northeastern part of the township, deriving its name from early settler Alexander Logan and family, post office from 1844.
