I'll try to find a copy of that book. I'm afraid that Lt. Harmon may be in an unmarked grave, however, it seems to me that a Lieutenant who survived for several days after being wounded would be known, and therefore, be buried in a grave with his name on the stone. I will honestly say that I don't know this to be true, and have much to learn. My own great-great grandfather was shot on the first morning at Gettysburg. He served with the 56th Pennsylvania Volunteer Infantry, and Gettysburg won't honor him by placing his name of the Pennsylvania Memorial. Thank you for answering my query.
