George Granville, 1st Baron Lansdowne had been created a baron by Queen Anne on 1 January 1712. On 6 October 1721 the Jacobite
Old Pretender "James III", who refused to recognise his peerage "Baron Lansdown" bestowed by Queen Anne, created him "Lord of Lansdown"," Viscount [ ]" and "Earl of Bath" in the
Jacobite Peerage of England, with remainder to his heirs male. On 3 November 1721 James created him "Duke of Albemarle", "Marquis Monck and Fitzhemmon", "Earl of Bath", "Viscount Bevil", and "Baron Lansdown of Bideford" in the
Jacobite Peerage of England, with remainder to the heirs male of his body, who failing to his brother, Bernard Granville, and the heirs male of his body. George died on 29 January 1735 and left no male progeny, and thus at his death the Barony of Lansdowne became extinct. His Jacobite titles, such as they were, were inherited by his nephew Bernard Granville, son of his brother Bernard. The younger Bernard died in 1776, when the Jacobite peerages created on 3 November 1721 became extinct, while those created on 6 October 1721 passed to his heir male. ==Earls of Bath; Fourth creation (1742)==
