Jim, I spent a couple of hours today walking thru Sewanee Cemetery and found nothing in regards to a gravestone. That cemetery is not on a steep hill also. I do live in Chattanooga and the National cemetery is on a steep hill. There are no records showing your Hamrick but there are so many unknown graves from the Civil War. The Chattanooga National Cemetery does state that reinternments were also brought here from previous battles in the surrounding area. I would be welcome to email you any pics of the cemetery if needed.
