Duke of Montrose is a title that has been created twice in the Peerage of Scotland. The first creation was in 1488 for David Lindsay, 5th Earl of Crawford. He was forced to forfeit the dukedom later in 1488, but it was restored to him in 1489, although only for his lifetime. Thus, it was not inherited. The title was created anew in 1707, again in the Peerage of Scotland, for James Graham, 4th Marquess of Montrose. James was elevated as a reward for his important support of the Act of Union. It has remained since then in the Graham family, and the title is also tied to the chieftainship of Clan Graham. The Duke's subsidiary titles are: Marquess of Montrose, Marquess of Graham and Buchanan, Earl of Montrose, Earl of Kincardine, Earl Graham, Viscount Dundaff, Lord Graham, Lord Graham and Mugdock, Lord Aberruthven, Mugdock and Fintrie and Baron Graham, of Belford. The titles of Earl Graham and Baron Graham are in the Peerage of Great Britain; the rest are in the Peerage of Scotland. The eldest son of the Duke uses the courtesy title of Marquess of Graham and Buchanan. The family seat is Auchmar House, near Loch Lomond, Stirlingshire. It was previously Buchanan Castle, near Drymen, Stirlingshire.
