This is the most popular Scott tartan in modern times. Earliest reference possibly 1829 in a letter from Sir Thomas Dick Lauder to Sir Walter Scott in which he tells Scott that he had seen this tartan in a manuscript prepared for the brothers John Sobieski and Charles Edward Stuart. Scott rejected the idea very firmly. Jamie Scarlett pointed out (April 2006) that it was interesting that the tartan for Rob Roy MacGregor's greatest publicist - Scott seemed to owe its origins to the Clan Gregor tartan of 1819.
