These men will almost certainly have service records which you can order here.

Locating images of any Confederate soldier will be quite a challenge. We don't know that images of the men you have in mind were ever made. Many of the images that were made are not identified -- we have no idea who the soldier pictured might be or when the image was made. If the images you want did exist, it would be anybody's guess as to what descendant had them today.

Since images such as you requested are rare, they are quite valuable. Descendants frequently sell them to a collectors for less than they are really worth.

You could contact the Georgia State Archives to learn what images of Georgia they may have.
