About Duncannon, PA

Duncannon was originally called Petersburg, and under the latter name was laid out in 1792. The present name is derived from Duncan's Island in the Susquehanna River. The Puritan missionary David Brainerd visited the area in the 1740s. In his journal he describes his trip on the Susquehanna and his brief stay with an Indian tribe on Duncan's Island, across the river from present-day Duncannon. The Mutzabaugh family has close connection to the town, as their market (now grocery store) named after the family has been a presence in the town since 1920, opening originally along the old railroad crossing between Market Square and High Street.
