Great work! Thanks for posting the information. Greg Coco's book on Gettysburg's Confederate Dead lists Hugh Key, David D. Munn and Augustus L. Short as having been buried on John Edward Plank's farm near Willoughby Run, which was a hospital for Hood's Division. Munn's grave was pinpointed under a locust tree. After the war Key was reinterred in the Georgia lot at Hollywood cemetery in Richmond, and Munn and Short are also believed to have been buried there as unknown soldiers on 3 August 1872.
