Don Jacobo Francisco Eduardo Fitz-James Stuart y Colón de Portugal 3rd Duke of Berwick (28 December 1718 – Valencia 30 September 1785) was a Jacobite. On the death of his father James Fitz-James Stuart in 1738 he inherited his titles of Duke of Berwick and Duke of Liria and Xerica. (He also possessed many other titles in both Spain and England.) His mother was Spanish and on her side he was a direct descendent of Christopher Columbus.
