Ann McMillen, 1739-1820
10 stops across Pennsylvania. 1739–1820
Ten stops through one Pennsylvania life, 1739 to 1820: Somerset County where she was born, the Lancaster square of her 1761 marriage, the York of her second marriage where Congress sat in 1777, and the Susquehanna at Airville, the last place her record names, with two National Register places there from her own time.
Turn the pages to see each stop on a map from its own era. Pins mark where each marker stands and where the federal record places each listing, sometimes a few miles from the ground described.
Green diamonds mark where Ann McMillen lived, as the family's own records place it. Each distance is a straight line from that place, not from a door.
