James Ley, 3rd Earl of Marlborough
James Ley, 3rd Earl of Marlborough (28 January 1618 – 3 June 1665) was a British peer and Member of Parliament, styled Lord Ley from 1629 to 1638. Life. He was the only son of Henry Ley, 2nd Earl of Marlborough, whom he succeeded in 1638. Marlborough was General of Ordnance in the West for Charles I in 1643, during the English Civil War, and later in the year was appointed Admiral of the Royal fleet at Dartmouth. Through diligent study, Marlborough gained a reputation as an able mathematician and navigator. He founded an English  colony in St Croix in 1645, which was, however, destroyed in 1650. He proposed to embark on another colonizing venture in 1649, which was apparently unsuccessful. After the Restoration, in late 1661, he was given command of HMS "Dunkirk" and sent out as commodore of a squadron to claim Bombay, which had been ceded to England as the dowry of Catherine of Braganza on her marriage to the English king, Charles II. The fleet carried the last Portuguese governor of Bombay, António de Melo de Castro and the first English governor Abraham Shipman. However, the Portuguese were able to stall  the handover by a variety of pretexts, and Marlborough was forced to land the garrison troops sent with him on Anjadip Island and return home with his ships. He was in 1664 nominated as the next Governor of Jamaica but was shortly afterwards given command of the 70-gun second-rate "Old James" and was killed in 1665 at the Battle of Lowestoft attempting to recover a captured ship. He was succeeded by his uncle William.
