James Brydges, the son and heir of the 8th Baron of Chandos of Sudeley, served a variety of governmental roles. He was a member of Parliament from 1698-1714, paymaster general for the forces abroad during the War of the Spanish Succession from 1705-1713, and was lord lieutenant of the counties of Hereford and Radnor, as well as serving as chancellor of the University of St. Andrews.

At his father's death in 1714, Brydges was created Viscount Wilton and Earl of Carnavon. In 1719 he was created Marquess of Carnvaron and Duke of Chandos. The patron of composr Georg Friedrich Handel and closely connected to poet Alexander Pope, Chandos built a large house at Canons in Middlesex. He became involved in financial difficulties, however, and after his death in 1744, the house was pulled down to be sold for its materials.

Chandos' grandson James, 3rd Duke of Chandos, died without sons to inherit in 1789, and all the family titles except one became extinct. James' daughter Anna Elizabeth retained one title, becoming Baroness Kinloss. In 1796 she married Richard Grenville, who became the Marquess of Buckingham. In 1822, he was created Duke of Buckingham and Chandos.
