Sir James Steuart Denham died at Cheltenham in his ninety-fifth year; at the time of his death he was the senior general in the British Army. He had married on 30 September 1772 Alicia, daughter of William Blacker of Carrick Blacker, County Armagh, but they had no children, so he was succeeded in the baronetcies by his second cousin Henry Steuart Barclay.
