- Notes:
The entry in W. and A. Smith's 1850 publication 'Authenticated Tartans of the Clans & Families of Scotland' reads: "We had our specimen from the Manufacturer: it has always been known as 'The Robertson,' and has been approved of by all the authorities to whom we have referred it."
The Robertsons, known as Clan Donnachaidh, are claimed to be descended from the Celtic Earls of Atholl. Wilsons of Bannockburn, a weaving firm founded c1770 near Stirling, had a sett in which purple replaced the blue recorded by James Logan in the 'Scottish Gael' (1831). The Pattern books are in the National Museum of Antiquities, Edinburgh. This tartan dates to 1819.
