I have an old photo of Clark Adair, he is one of 38 men in the photo. On the back it says No. 35 Uncle Clark Adair (an uncle of Grandma Feighner) (Civil War Picture). Does anyone know who this may be. I am willing to trade a copy of the photograph for information. The picture is 7 inches by 9 1/2 inches No date on the picture other than (Civil War Picture) on the back.
