High Quality Content by WIKIPEDIA articles! The title Duke of Leeds was created in 1694 for the 1st Marquess of Carmarthen and became extinct on the death of the 12th Duke in 1964. The Dukes of Leeds also held the titles Marquess of Carmarthen (created 1689), Earl of Danby, in the County of York (1674), Viscount of Osborne, of Dunblane (1673), Viscount Latimer, of Danby in the county of York (1673), Viscount of Dunblane (1675), and Baron Osborne, of Kiveton in the County of York (1673). All of the titles were in the Peerage of England except the Viscountcies of Osborne and Dunblane, which were in the Peerage of Scotland. The father of the 8th Duke was created Baron Godolphin on 14 May 1832; this creation was in the Peerage of the United Kingdom. The barony had remained merged with the dukedom since 1859. The heir apparent to the Duke of Leeds was styled Marquess of Carmarthen, Lord Carmarthen's heir apparent was styled Earl of Danby, and Lord Danby's heir apparent was styled Viscount Latimer. The "Leeds" the Dukedom was named for was the Leeds in Yorkshire, and the title did not (as is sometimes claimed) refer to the Leeds or Leeds Castle in Kent.
