It is possible to order copies of civil war photos from the US archive at Carlisle, PA. http://www.carlisle.army.mil/usamhi/PhotoDB.html I entered Minnesota as a searchword and got 255 hits. I scanned them and there are some group photos and some of individuals who are named. I did not take the time to look at all of them. The same search should work for any state if you know you have an ancestor who served in that war. My husband's PA ancestor was in a New York regiment so sometimes you have to look outside your local area. Karen
