George Augustus Frederick John Murray, 6th Duke of Atholl, KT, DL (20 September 1814 – 16 January 1864) was a Scottish peer, important landowner, and freemason.
On 30 August of that year he attended the 13th Earl of Eglinton's tournament in Ayrshire in the guise of 'The Knight of the Gael', accompanied by a retinue of his Highlanders.
So impressed was she with their turnout that she ordered they be presented with colours, giving them official status, and leading them to be Europe's only legal private army.
[1] In October 1854, shortly before the death of the Jacobite pretender Charles Edward Stuart, Count Roehenstart, Atholl welcomed him as a guest at Blair Castle.
Atholl died in 1864, aged 49, from cancer of the neck, and was succeeded in his peerages and estates by his only child John.
