He represented Charleville in the Irish House of Commons and Warwick in the British House of Commons. He died unmarried at the age of thirty-three and was succeeded by his half-brother, the seventh Earl. On his death 1798 the titles passed to his second but eldest surviving son, the eighth Earl. He was a General in the Army and fought in the Revolutionary and Napoleonic Wars.

His eldest son, the tenth Earl, fought in the Second Boer War but died childless in 1925. He was succeeded by his younger brother, the eleventh Earl. He also died childless and was succeeded by his second cousin, the twelfth Earl. He was the grandson of the Hon. John Boyle, third son of the eighth Earl. Lord Cork was an Admiral of the Fleet and notably commanded the combined expedition for the capture of Narvik in 1940. He was childless and was succeeded by his nephew, the thirteenth Earl. He was the eldest son of Major the Hon. Reginald Courtenay Boyle. He served as a Deputy Speaker of the House of Lords and as Deputy Chairman of Committees in the House of Lords from 1973 to 1978.
