Duke of Montrose (named for Montrose, Angus) is a title that has been created twice in the Peerage of Scotland. The title was created anew in 1707, for James Graham, 4th Marquess of Montrose, great-grandson of famed James Graham, 1st Marquess of Montrose. Montrose was elevated as a reward for his important support of the Act of Union. It has remained since then in the Graham family, tied to the chieftainship of Clan Graham. The Duke's subsidiary titles are: Marquess of Montrose (created 1644), Marquess of Graham and Buchanan (1707), Earl of Montrose (1503), Earl of Kincardine (1644), Earl Graham (1722), Viscount Dundaff (1707), Lord Graham (1445), Lord Graham and Mugdock (1644), Lord Aberruthven, Mugdock and Fintrie (1707) and Baron Graham, of Belford (1722). 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.
