The duke of Dorset's reappointment to the lord-lieutenancy in 1751, with his son Lord George Sackville as secretary of state for Ireland, strengthened the primate's position and enabled him to triumph over the popular party on the constitutional question as to the right of the Irish House of Commons to dispose of surplus Irish revenue, which the government maintained was the property of the Crown.
It was written by Thomas Sackville, Lord Buckhurst and Thomas Norton in collaboration.
The church contains a monument to Lord Edward Bruce, killed in a duel with Sir Edward Sackville, afterwards earl of Dorset, in 1613.
The barony passed to his nephew, Sackville George Lane-Fox (1827-1888), falling into abeyance on his death in August 1888, and the dukedom passed to his cousin, George Godolphin Osborne (1802-1872), a son of Francis Godolphin Osborne (1777-1850), who was created Baron Godolphin in 1832.
Inside the fortress lies the old Protestant burying-ground, with tombs of Sackville, of John Murray, of Sir Francis Vincent, last ambassador but one from Great Britain to the republic, of Consul Smith, whose collection of books forms the nucleus of the King's library in the British Museum, and of Catherine Tofts, the singer, Smith's first wife.
