Robert Stewart, 1st Earl of Orkney and Lord of Zetland (Shetland) (spring of 1533 – 4 February 1593) was a recognised illegitimate son of James V, King of Scotland, and his mistress Eupheme Elphinstone.
[4] During the Reformation Crisis, on 9 February 1560 he testified against the Hamiltons, the Duke of Châtellerault and Earl of Arran, and the Protestant Lords of the Congregation to James MacGill and John Bellenden of Auchnoule.
[5] Mary, Queen of Scots returned to Scotland on 19 August 1561, arriving unexpectedly at Leith at 10 o'clock in the morning with her entourage of 60 companions in two galleys.
Again, in March 1565, Robert Stewart took part in running at the ring at the sands of Leith,[10][11] and the contestants included a newcomer at court Lord Darnley.
The new earldom replaced a short-lived Dukedom of Orkney, which had been awarded in 1567 by Mary, Queen of Scots, to her notorious third husband James Hepburn, 4th Earl of Bothwell.
