Maps and Atlases

In the Tredyffrin - Easttown area maps and atlases are a great resource for local history research. Most of these maps and atlases are available online. The coverage of these atlases is variable, especially those that were sponsored by the Pennsylvania Railroad, which focus around the Main Line. No map is 100% accurate but the quality of these atlases is good and only occasionally do they seem to err, and then only in small ways.

There are 2 comprehensive online resources, Andy's Antique Atlases, and Radnor Historical Society list (for maps of the City of Philadelphia go to Greater Philadelphia GeoHistory Network). To view a map in Andy's list, first go to the relevant index of maps and choose the map number you wish to view. Then go to the Selection page and click on the map. To view a map on the Radnor list, go to the index of maps and select a map. Then select the page you want in the top right of the page. See the example below:

The atlases in the following list are, in most cases, available on both the resources. There are small variations between the resources so if one does not quite provide the information sought, it is worthwhile looking at the other resource.

The first atlas covering Tredyffrin and Easttown was published in 1873. Earlier maps exist of lower resolution, but no atlases.
