THIS is Wilsons’ No 155 from the 1819 but this count from a c1830-40 Wilsons’ sample named Caledonia in a Scott Adie pattern book photographed by the Scottish Tartans Museum in Franklin North Carolina. Reputed to have been worn by members of the ill-fated Darien Expedition to America in 1698. This is a common tartan for people that don’t have a specific tartan.
