After the 1st Marquess of Buckingham's death in 1813, his titles passed to his son Richard Temple-Grenville, 2nd Marquess of Buckingham. He married Lady Anne Eliza Brydges, the only child of James Brydges, 3rd Duke of Chandos (a title which became extinct on his death in 1789), and assumed by Royal licence the additional surnames of Brydges-Chandos in 1799. In 1822 Lord Buckingham was created "Earl Temple of Stowe", in the County of Buckingham, "Marquess of Chandos" and "Duke of Buckingham and Chandos", all in the Peerage of the United Kingdom. The earldom was created with remainder, failing male issue of his own, to (1) the heirs male of the body of his deceased great-grandmother Hester Grenville, 1st Countess Temple, and (2) in default thereof to his granddaughter Lady Anne Eliza Mary Temple-Nugent-Brydges-Chandos-Grenville, daughter of his son Richard, who succeeded as second Duke in 1839.
