The title of Duke of Montrose was created in the peerage of Scotland in 1488 for David Lindsay. It was forefited, and then returned but only for the period of the holder's lifetime. Thus, it was not inherited. The title was bestowed anew in 1707, again in the peerage of Scotland, on the fourth Marquess of Montrose, and has since been in the Graham family.
The Duke's subsidiary titles are: Marquess of Montrose (created 1644), Marquess of Graham and Buchanan (1707), Earl of Montrose (1505), Earl of Kincardine (1707), Earl Graham of Belford (1722), Viscount Dundaff (1707), Lord Graham (1415), Lord Aberruthven, Mugdock and Fintrie (1707) and Baron Graham of Belford (1722). The titles Earl and Baron Graham of Belford are in the peerage of Great Britain; the rest are in the peerage of Scotland. The eldest son of the Duke uses the courtesy titleMarquess of Graham and Buchanan.
