There is no evidence that Wilson's Tartans had anything whatsoever to do with any ancient regional or pre-1746 patterns. The Tartans worn at the Battles of Sheriffmuir or Culloden have almost all been lost forever. In 1816 an attempt was made to match Clan to 'true' Tartan. Many setts were gathered but these had more to do with regimental uniforms together with Wilson's successful marketing, than any older patterns. But the idea that Tartan and Clan were inexorably coupled had become firmly established.
