1803

I would say around the 1820. The Maclaren and Ferguson are the same apart from the yellow and white stripes, prior to 1820 the MacLaren was the Regent Tartan being woven by Wilsons for a number of years. Upon the Regent becomming King it was redundant as the Regent tartan but Wilsons apparently contunued to produce it. I would say it was snapped up by the MacLarens in the rush for tartans around that time. I would guess that the same is true for the Fergusons. Or was the Regent tartan a altered copy of a older Ferguson tartan. Good hunting on your quest

You must have been reading my book . And before the MacLaren was Regent it was Pattern No232 which means it pre-dates 1811. There is no evidence of the Ferguson version before a sample c1830 but in keeping with a lot of Wilsons' numbered patterns it's entirely possible, and probable, that it existed as a numbered sett slightly earlier. There is a completely different tartan in the Cockburn Collection (c1810-15) that is a simple asymmetric check. It has all the characteristics of being a numbered sett and there is no evidence to show why it was named Ferguson.
