Derived from the Gaelic Mhaoil-Iain, meaning “son of one who bore the tonsure of St John”, the MacMillan clan are a clan most closely associated with the Scottish Highlands.
Originally located in Lochaber, the clan would eventually settle at Castle Sween, on the banks of Loch Sween before moving on to their modern seat at Finlaystone House in Renfrewshire – where the current chiefly family sits.
The current clan chief is George Gordon MacMillan of MacMillan and Knap.
