KING JOHN
Known as ‘Toom Tabard’ (or ‘Turncoat’), he was born either in c.1240, or in 1249/50. He was created Baron of Bywell in Northumberland, but forfeited this honour in 1285. He was elected King of Scotland by Edward I of England on 17 November, 1292, thus bringing to an end the First Interregnum. He was crowned on 30 November, 1292, at Scone Abbey, Perthshire.
King John married, before 7 February, 1281 (although no evidence exists as to where):
Isabella
She was the daughter of John de Warenne, 6th Earl of Surrey, by Alice, daughter of Hugh X de Lusignan, Count of La Marche, by Isabella of Angoulême, widow of John, King of England, and she was born in 1253. The date of her death is not known.
Issue of marriage:
1 King Edward ( 
see here).
2 Henry
He was killed on 16 December, 1332, at the Battle of Annan.
3 Margaret
She died unmarried.
4 Anne (?)
There is doubt that she ever existed. She is said to have married Brian FitzAlan of Bedale.
KING JOHN
He abdicated on 10/11 July, 1296, at Brechin. Scotland was left without a King, and thus began the Second Interregnum, which lasted until 1306, when Robert Bruce seized the throne in defiance of Edward I, who had tried during the years it stood vacant to take it himself, and make Scotland a fief of England.
King John died between 4 March, 1313, and 4 January, 1314, either at Château Gaillard, Normandy, or at Bailleut-en-Gouffern, Normandy. He was probably buried in the Church of St Waast, Normandy.
