If you haven't already done so, I suggest you contact the The Franklin County Historical Society located at 175 E. King Street, Chambersburg, PA. Genealogical archives, library and museum are open to the public on Thursday, Friday and Saturday, except holidays, 10 AM to 4 PM during the winter. The library and archives are also open during the winter months on Tuesday evenings from 5 PM to 8 PM. For additional information contact the Franklin County Historical Society at
history@pa.net or 717-264-1667.

I am a descendant of Peter and Maria Lesher Brubaker but would be interested in anything you may learn about Abraham and his family.
