Cuz,
I checked out James E. Nunn.
James E. Nunn married Esther E. Wilhite the 3rd. of March 1857 in Jackson Georgia.
So.... I would have to say that James belongs to rechord number two.
I don't know if there is a list of the dead at Fort Delaware but I would think there is one. If so Augustus should be listed on it.
