Lord Gage was succeeded by his eldest son, the second Viscount. He represented Seaford in the House of Commons and served for many years as Paymaster of Pensions. In 1780 he was created Baron Gage, of Firle in the County of Sussex, in the Peerage of Great Britain, with remainder to heirs male, and in 1790 he was made Baron Gage, of High Meadow in the County of Gloucester, also in the Peerage of Great Britain, with remainder to his nephew and heir presumptive Henry, the eldest son of his younger brother, the aforementioned Sir Thomas Gage. On Lord Gage's death in 1791, the barony of 1780 became extinct while he was succeeded in the barony of 1790, the baronetcy and the Irish titles by his nephew Henry, the third Viscount. He was a Major-General in the Army. As of 2010[update] the titles are held by his great-great-great-grandson, the eighth Viscount, who succeeded his elder brother in 1993.
