Not to belabor this, but Pvt. Harwood was probably buried by his fellow soldiers wherever the encampment was, probably with a wooden marker. The soldiers themselves were probably not being paid, and unless there were a stonemason among them who had his tools along on the trek they would have been unable to provide a permanent marker. This was a perilous situation, and it is unlikely that a family member came for the remains. There may be a memorial marker for him in a home cemetery. You really should look at the original rolls (don't rely on National Park Service abstracts) and get the names of the other men in his Company. If you then look up the pension application files for each of them who lived to apply, you just might find a narrative relating to Pvt. Harwood's death. There just might be a receipt roll showing that a family member collected his final pay (this is unlikely). Other records in the National Archives might show that his family subsequently petitioned Congress for reimbursement for his personal effects such as a rifle, or that a private bill was introduced on their behalf in Congress for this purpose. His heirs would have been entitled to his final pay and, if this was not paid until years after the war, possibly depreciation certificates in lieu of payment. Items on this could be in the "Final Payment Ledgers," which have been recently *partially* abstracted; they mostly contain data on final pension payments. If he was married, his widow might have petitioned the Court in his home County for some financial support, particularly if there were children from the marriage. Good hunting, Judy
