The titles of Earl of Hertford and Marquess of Hertford have been created several times in the peerages of England and Great Britain. The third Earldom of Hertford was created in 1559 for Edward Seymour, who was simultaneously created Baron Beauchamp of Hache. His grandson William Seymour was subsequently created Marquess of Hertford and restored to the title of Duke of Somerset; the Marquessate became extinct in 1675 and the other three titles in 1750. The family seat is Ragley Hall, near Alcester, Warwickshire.
