Those researching their ancestors in Pennsylvania know that county boundaries changed frequently in the years since 1682. To make these boundary changes easier to see, I animated them.
I used portions of the “Genealogical Map of the Counties” available at the Pennsylvania Historical and Museum Commission. I simply snipped the individual images in their sequence of state maps that show county boundaries and made a short flash animation.
Unfortunately these maps do not show cities and towns, but if you know the county you are interested in, you can see when it was created and how it changed over the years.
