McCALL, HORN, BARR. Hi, all. My mother's family lived in the SE PA area, (Freemansburg, Easton, Bethlehem) area for generations. Anyone on the list who is researching any of these names? The McCALLs/BARRs were the the most recent arrivals, sometime prior to 1862, from Ireland. The HORNS were Pennsylvania Deutsch. Molly
