I only found one thing regarding the Chapmans you noted in my Harrison County history books and, since you noted the military record of the younger, I thought you might like to know about it. In The History of Harrison County, Illustrated, The Goodspeed Publishing Company, 1888 (Page 329 in the reprint) it is noted that a George W. Chapman served as a Private in Company E, Twenty-third Missouri Regiment Volunteer Infantry. This regiment was formed in Harrison County during the summer of 1861. They fought under General Prentiss at the Battle of Shiloh. See this website for more information on the 23rd Missouri: http://members.aol.com/RGooch6760/23rdMoVol.html Kevin Sutton Flower Mound, TX.
