If your John Sutherland was in the 79th in the Peninsular Wars as well as at Waterloo, which it seems he was, he would have earned the Military General Service Medal (MGSM). On the Roll of the MGSM is Corporal John Sutherland of the 79th with clasps for Busaco, Fuentes D'Onor, Salamanca, and Pyrenees. The MGSM was issued in 1848. The Waterloo Medal was issued in 1816-17. He hopefully survived to receive the Waterloo Medal and perhaps the MGSM, though many didn't live long enough to receive the latter. If he did, it would be a wonderful "pair".
The battle for Busaco was fought on 27 September 1810;
The battle of Fuentes de Oñoro was from 3 to 5 May 1811;
The battle of Salamanca was fought on 22 July 1812; and
The battle of the Pyrenees was a large-scale offensive launched on 25 July 1813.
