HistoryA character grade: shown, never part of Franklin Township’s overall grade.
Pennsylvania towns list about as much on the Register as the country (a typical Pennsylvania town has 2.1 per 10,000 residents, the U.S. 2.4), so Franklin Township’s 0.0 sits below most of its state (25% of Pennsylvania towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.

The southernmost part of the township was originally disputed territory between Pennsylvania and Maryland, resolved eventually by the Mason–Dixon line. The southernmost section of the township formed the northern section of New Munster, a large settlement tract established by Maryland and named after the southern province of Munster in Ireland. New Munster acted as an early genesis point and catalyst for large Scots-Irish settlement and expansion into Chester County and points west in Pennsylvania. The Wooleston Grist Mill, also known as Tweed's Mill or Mackey's Mill, formed part of the New Munster tract and settlement.
