Vice-Admiral James Berkeley, 3rd Earl of Berkeley, (aft. 1679 – 17 August 1736) was the son of Charles Berkeley, 2nd Earl of Berkeley and the Hon. Elizabeth Noel. He was known by the courtesy title of Viscount Dursley prior to succeeding as Earl of Berkeley in 1710. He was a distinguished Royal Navy officer who served as First Lord of the Admiralty during the reign of King George I. Viscount Dursley received his commission as a lieutenant in the Royal Navy on 10 March 1699 and was promoted to captain on 2 April 1701. He was also a Member of Parliament (MP) for Gloucester 1701–1702. He took part in the battle off Málaga under Admiral Rooke, commanding HMS Boyne. He was summoned to Parliament by writ of acceleration as Baron Berkeley on 5 March 1705, and continued to rise in the Navy. Dursley commanded HMS St George in 1706, and narrowly escaped the Scilly naval disaster in which Sir Cloudesley Shovell in HMS Association was lost on 23 October 1707. The St George ran aground on the same ledge as the Association, but was lifted off with the next wave. It is said that it was Dursley who gave his close friend Shovell the priceless emerald ring which features prominently in some of the legends still told about the disaster. With the death of Sir Clowdisley Shovell, a promotion of flag-officers was made. Rear Admiral Robert Fairfax, was to be commissioned as a Vice Admiral of the Blue (it was signed by the Lord High Admiral and gazetted) but was then cancelled, and Dursley, who was his junior and because of the political influence of his family, made Vice Admiral of the Blue in his stead with seniority of 10 January 1708. Dursley was then promoted to Vice Admiral of the White in late 1708. In April 1709 he recaptured HMS Bristol, which had been taken by the French a short time earlier, but she sank shortly afterwards. Dursley was promoted to Vice Admiral of the Red in December 1709. With the death of his father on 24 September 1710, Dursley succeeded to his titles and became the 3rd Earl of Berkeley. That year, he was also made High Steward of Gloucester, Warden of the Forest of Dean, Constable of St. Briavel's Castle, and Lord Lieutenant of Gloucestershire, which he held until 1712, and then from 1714 to his death,
