My information says Alexander LeGrand Whitehall (son of Thomas, grandson of Alexander LeGrand) left Currituck Co shortly after the death of Thomas. I have a copy of Thomas' will from Currituck Co. From there the family went to Fountain Co. IN and some from IN to Mercer Co. IL -- where I very nearly still am 150+ years later. My info has only that James Whitehall died in, perhaps, Washington. I didn't know if that was Washington, IL, near Peoria or Washington State or Washington, D.C. I gather it is Washington (state).
Have you info on the Battle of Great Bridge? I thought it was in Currituck Co., but found a map that suggests it was nearby but in VA.
