Pennsylvania (1820 census): Philadelphia County (Outside of Philadelphia City) Pt. 1. Includes Kingsessing Twp.; Province Island Barracks; Fort Mifflin; ...FHL US/CAN Census Area [ 181414 ]

The Annals of Philadelphia and Pennsylvania explained some of its history:

Province Island was near Fort Mifflin according to a site listing Pennsylvania Frontier Forts.
