Dugald Dalgetty is based upon James Turner and Robert Monro, 17th century soldiers. Dalgetty's name is derived from Captain Delgatty of Prestonpans, an acquaintance of Scott. Menteith is based upon John Graham, Lord Kilpoint (1613-1644). Evan Dhu represents Ewen Cameron of Lochiel (1629-1719). Montrose represents James Graham, 1st Marquis of Montrose (1612-1650). Several parts of the novel are influenced by traditions concerning the Stewarts of Ardvorlich, specifically James Stewart of Ardvorlich. The novel's castle of Darnlinvarach is commonly said to represent Ardvorlich House. The latter actually appears in the novel as the castle of Ardenvohr, which may be somewhat based upon Dunstaffnage Castle.
