John Sheffield (born 7th April 1648, died 24th February 1720) was the son of Edmund Sheffield, second Earl of Mulgrave, and succeeded his father in 1658. John Sheffield had an eventful military and naval career, the two professions being in his time curiously considered as one. As a sailor he took part in the fight at Solebay in 1672 under the Duke of York, and afterwards was Captain of the "Royal Catherine." As a soldier Lord Mulgrave was Colonel of the Holland Regiment, Governor of Hull, and commanded a force at Tangier. In 1674 he was made a Knight of the Garter. He was a member of the Privy Council and Lord Chamberlain of the Household. In 1694 he was made Marquis of Normandy, and in 1703, Duke of Normandy, and shortly afterwards Duke of the County of Buckingham. He was a book-lover, and an author of some repute in his own time.
