Lord Burlington was succeeded in the earldom of Cork and the other remaining titles by his third cousin John Boyle, 5th Earl of Orrery, who became the fifth Earl of Cork as well (he was descended from the "third" son of the first Earl of Cork, and had also inherited the titles of Baron Broghill and Baron Boyle of Marston in the Peerage of Great Britain, thus a seat in the British House of Lords until 1999 (see the Earl of Orrery for earlier history of this branch of the family). He was a writer and a friend of Jonathan Swift, Alexander Pope and Samuel Johnson. He was succeeded by his second but eldest surviving son, the sixth Earl. 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, Edmund Boyle, 7th Earl of Cork. The seventh Earl is remembered only for the fame of his second wife Mary Boyle, Countess of Cork and Orrery, the celebrated Lady Cork whose salon was a centre of intellectual life for fifty years. On his death in 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.
