William Nassau de Zuylestein, one of the most trusted companions of his kinsman William of Orange, was created Earl of Rochford and Viscount Tunbridge in 1695 (both in the Peerage of England). He was succeeded by his son William, the second Earl, who was killed at the Battle of Almenar, and then by another son, Frederick, the third Earl. Frederick’s son, William Henry, the 4th Earl, was a diplomat and a statesman. Having gained experience as envoy at Turin from 1749 to 1753, he was Ambassador to Madrid from 1763 to 1766 and to Paris from 1766 to 1768. From 1768 to 1775 he was one of the secretaries of state. He left no children when he died on 28 September 1781, and was succeeded by his nephew, William Henry, the 5th Earl. The titles became extinct on the latter’s death in September 1830.
