Hi Ed,
The book has a section on his POW experiences in every place he was held captive. He mentions a number of men in this section but I am not sure if they have anything to do with the 18th GA or not - I have only read the war time section.
The Lemon House still stands in Acworth about two blocks from the book store that sells the book I mentioned - and it remains in the Lemon family today.
