Thank you.
From what you both have told me, I do believe that the three Buck brothers (my ggrandfather and his two brothers) were the Bucks listed in Company A, 49th Tenn Infantry, and that it was my Benjamin who died at Rock Island.
I have been reading about Rock Island prison camp, and it was known as the "Andersonville of the North." Reading about the conditions there breaks my heart.
Thanks for your kindness,
Donna
