A sample of this distinctive and ancient tartan exists in the Cockburn Collection in the Mitchell Library in Glasgow dating before 1810 when the collection was made. It was first published by Grant in 1886. The MacLaines of Lochbuie challenged the right of chiefship for the Clan MacLean. The matter was settled by 'tanistry' and Duart was recognised as chief, even though Eachin Reganach was in fact the elder brother of Lachlan, the first chief of the MacLeans of Duart.
