I forgot to point out that land boundaries were approximate and confusing at the point in time, when the area was just being settled, and it was frontier territory. Sometimes landowners recorded their deeds in two counties, if they were near a boundary line, to make sure they had the deed recorded in the right county. It's always wise to search surrounding counties for records. So you may find a deed involving a good chunk of Rowan in Orange, or vice versa, and possibly in both counties.
