My great great grandfather, John Hamilton born March 11, 1821 in Airdrie, Scotland according to family oral history served in the Crimean War and was at the Battle of Balaklava. He lost an arm and was decortated by Queen Victoria. How can I find out if he really served in the army? Supposedly, he was in the 92nd Gordons. Any help would be greatly appreciated. His parents were George Hamilton and Ann Bryce who also lived in Airdrie.
