- Notes:
This sett appears first in the 1842 Vestiarium Scoticum and is the customarily accepted MacArthur tartan. MacArthurs were at one time linked with the MacDonalds and this tartan has the same basic form as the MacDonald, Lord of the Isles sett. MacArthurs, in Skye, held land as the hereditary pipers to the MacDonalds. There is also an older MacArthur of Milton tartan whose design reflects the links with Clan Campbell.
