Rodger, So very sorry for the delay, I misplaced your request until today. I did not find Newton listed with the returned North Carolina Dead from Gettysburg buried in Oakwood Cemetery, Raliegh, North Carolina.
There were some unknowns listed as returned from there sent to Raleigh.
But, he could also have been with the Hundreds of Confederate Unknown Dead (State not known) who now sleep in Hollywood Cemetery, Richmond, Virgina. Guess was not much help. Tim
