Below is a map from the late 1950s which denotes parish boundaries for those parishes located within Philadelphia County as well as some suburban parishes. Although the information is out-of-date and incomplete- for instance many of the national or ethnic parishes are not shown- it can be a useful resource. Click the map to see a larger image.
The following map, circa 1949, also denotes the boundaries of parishes located in Philadelphia County and nearby suburbs. However, this map includes the locations of ethnic and national parishes. Please note that the parish between Epiphany and St. Paul in South Philadelphia is not named. It is Annunciation B.V.M. Click the map to see a larger image.
