Mr. Allardice, I'm sure you have most of this information already but if you would like to see the genealogy and history of Col. William Harry Bishop of the 7th Mississippi check out this link. This was compilled by a descendent of his. I can provide you her email address if you wish to contact her. Col. Bishop was killed at the Battle of Franklin and he is buried at McGavock Cemetery there. Sources tell me the Carter House Museum has a picture of him.
