John Stewart, 1st Earl of Atholl (c. 1437–1442 – 15 September 1512),[1] also known as Sir John Stewart of Balveny, was a Scottish nobleman and ambassador.
He was created Earl of Atholl in around 1457,[3] the first earl of the eighth creation of the title. He is believed to have had a hand in suppressing the rebellion of John Macdonald, 11th Earl of Ross, the last of the Lords of the Isles. John Stewart became ambassador to England in 1484.
John Stewart married twice and had several children. However, the exact number, names, and the attribution of his children to their mothers is unclear.
Sometime before April 1475, he married as his second wife, Lady Eleanor Sinclair (died 21 March 1518), daughter of William Sinclair, 3rd Earl of Orkney and Marjory Sutherland. They had two sons and nine daughters:
Lady Jean (or Janet) Stewart, married by contract dated 31 August 1507, James Arbuthnott of Arbuthnott. He had a crown charter of the feudal Barony of Arbuthnott, 29 January 1507. He left a testament dated 7 March 1521, and died before 13 March 1521.
According to legend, the Earl of Atholl had whisky, honey and oats added to Macdonald's water well, which so entranced or intoxicated him that Macdonald was easily captured. The mixture became a drink named Atholl Brose.
