Brad,
You can see the address that John posted for the IL State Databases. That's where the physical description, etc. came from.
If you go to the regimental page with the Adjutant General's Reports, you may also find something under the Scrapbook section, photo section, or the burials.
The website for this is <http://www.rootsweb.com/~ilcivilw/>
This is a USGenweb page. They also have State and county websites; and pension projects, etc. Their main page is at <http://www.usgenweb.org/>
Do you have any other information on him? Did he stay in Illinois or move to another State?
Ann
