Duncan is a sturdy Scottish classic, anglicised from the Old Gaelic Donnchadh, a compound of donn, “brown” or “dark-haired,” and cath, “warrior” or “battle.” The name slipped into the English record through two medieval Kings of Scotland, then won permanent literary billing as the ill-fated ruler in Shakespeare’s Macbeth. Because the bard borrowed rather than invented, the name still carries a faint echo of Highland authority rather than stage-prop tragedy. In modern America Duncan has never been wildly common—its long-term rank hovers between the 400s and 700s—yet it remains reliably familiar, helped along by the coffee-shop sign that turns up on many Main Streets. The sound is brisk and friendly (DUHN-kin or, in most British mouths, DUHN-kən), the image self-possessed: a name that signals quiet strength, a dash of literary pedigree, and just enough everyday recognition to avoid the perennial spelling lesson.
