My ancestor Thomas Alexander also lived in Shippensburg Pa in the 1770' and 80's. His first wife was Mary Barr of Cumberland Co Pa. They had one son William (no birthdate) who died in Washington Co. Indiana in the early 1800's Thomas Alexander had a brother George who also lived in Shippensburg Pa.in the 1780's I don't have any ifo on the family of George. This George would have been born in the 1740's. Also there is a Lowery family that settled in WashingtonCo. Indiana very near my Alexander's. Thomas Alexander is my 4th great-grandfather. born in Ireland in 1752 died in Jackson Co. Indiana in 1849.
