Patrick Andrew Wentworth Hope Johnstone

In 1701 the King made William Johnstone the Marquis of Annandale in recognition of his service. His oldest surviving son, James, the second Marquis of Annandale, died unmarried in Naples in 1730. The first Marquis' posthumous son, George, was the third Marquis and when he died unmarried in 1792 the titles became dormant.

In 1983, after a lapse of nearly two centuries, the Lord Lyon King of Arms officially recognized Major Percy Wentworth Hope Johnstone of Annandale and of that Ilk, hereditary Keeper of Lochmaben Castle and a descendant of the daughter of the first Marquis of Annandale, as Chief of Clan Johnstone. Upon Major Hope Johnstone's death later that year, his son Patrick Andrew Wentworth Hope Johnstone succeeded as Chief. In 1985 the House of Lords recognized the Chief's claim to the long-dormant titles of Earl of Annandale and Hartfell. The Chief resides with his wife, Countess Susan Josephine Ross Hope Johnstone at Raehills on their Annandale estate. They have a son, Lord David Johnstone, and a daughter, Lady Julia Johnstone.
