A Year in the Life of a Village: Plainfield 1910
In 1812, tavernkeeper Michael Forner laid out lots on a piece of land on the road from Carlisle to Newville. He called the new town Plainfield. Plans were afoot for a Grand Turnpike from Harrisburg to Pittsburgh, and Forney thought it "would more than probably go through his new town."It did not. Often referred to as Smokey Town, the name Plainfield was officially adopted with the opening of the Post Office. The map of Plainfield in the 1872 Atlas of Cumberland County shows the locations of the shops, two churches, the school, the hotel as well as the houses. Plainfield grew, and by 1910, the village had approximately 200 residents.
