Notes (May 2006) from Sir Malcom Macgregor of MacGregor, Chief of Clan MacGregor. "The exact origins are unknown, but it can be seen in the Cockburn Collection of the same period as the Highland Society of London sample of Red and Black (#1504). It is not known if it was sealed in the same way as the Red and Black. Sir William Cockburn was a fellow member of the Society with Sir John MacGregor Murray. Wilson's of Brannockburn listed this tartan as MacGregor Murray so there may well have been a personal association with it on the part of my g-g-g-g- grandfather. This tartan was worn by his only son, my g-g-g grandfather as commander of the MacGregor Bodyguard during the King's visit to Edinburgh in 1822." In their 1850 "Clans and Tartans of the Families of Scotland" William and Andrew Smith of Mauchline wrote: "Use and wont, and the approval of the Tartan Manufacturers, are our authority for the MacGregor Tartan here given." This sett also appears in Clans Originaux (BW June 2004). One assumes that this is 1525 but this version has black guards on the white whereas 1525 has none. Sample in STA Dalgety Collection. Also known as Red MacGregor and Red and Green MacGregor.
This tartan dates to circa 1800.
