My great-great-great-grand father Henry and gmother Barbra Ann Stough, moved from Cumberland County, Pa to Ohio. He was probably of Perry County and she of Cumberland. They were married in 1816 in Cumberland County. This is as far back as I have traced to this date. His son Christopher was a captain in the union army from Mansfield, Ohio. Part of Sherman's Brigade, they fought in Mississipi and at Vicksburg. This Au family is of German discent.
