Wearing kilts of other tartans than your clans.

[Morris at Heathfield]

This scenario just isn't true, certainly not always. At one point clan chiefs and chieftans were asked to provide samples of their tartan(s) for a collection being assembled by a London-based society, whose name and subsequent publication I do not recall of the top of my head. Many of the chiefs then took it upon themselves to research their tartan(s) and provide examples as authentic as they could.

Several of the tartans predate the 1745 uprising and subsequent proscription, such as Campbell and the red Morrison.

Although I haven't attempted to catalog all of the clan tartans collected by the Highland Society of London, the overall impression I've gathered is that most of the clan chiefs resorted to selecting tartans designed by Wilson's of Bannockburn. Some clan tartans were taken from artifacts believed to have come from the '45. According to the late James D. Scarlett, the Campbell tartan dates to 1749. The Black Watch used some other tartan(s) before then. It did not come to be regarded as as a Campbell clan tartan until much later. The Red Morrison tartan dates to 1747 at the latest, but it was not reproduced by industrial weavers until after its discovery in 1935, over a hundred years after the first batch of clan tartans appeared. There is no reason to believe it was regarded as a clan tartan before then.

Regarding the topic of this thread, I do aim to respect custom and tradition, even when its origin can reasonably be placed within two centuries of the present day. However, in my opinion, that kind of leaves me without a tartan.
