How Mifflin came to be

From Wikipedia’s history of Mifflin.

Read it all →

Mifflin was founded as the town of Patterson. At one time, Mifflin, as well as the small community of Denholm lying directly north of the town, was an important stop along the Pennsylvania Railroad. The railroad tracks still pass through the town, but they are now owned by the Norfolk Southern Railway.

The Pennsylvania Railroad depot still stands in Mifflin, although it has long been abandoned. Mifflin is named after Thomas Mifflin, the first Governor of Pennsylvania.
