This is the sett that appears in the Vestiarium Scoticum as MacIntosh (Vestiarium Scotorum (1842) 87, Plate XXXI). There is no historical connection between the names Nisbet and MacIntosh to explain this, and it is interesting to note the similarity with the Dunbar tartan (where the white stripes are black) which also originates in the Vestiarium. The Nisbets came from the old barony of Nisbet in the parish of Edrom, Berwickshire, as early as 1160. Details from RC Nesbitt's 'Nisbet of that Ilk', 1941.
