William Graham, 1st Earl of Montrose (1464 – 9 September 1513) the Scottish Lord of Parliament, who was raised to an earldom by James IV of Scotland, died with his monarch at the Battle of Flodden.

The effect of Flodden was to wipe out much of the current generation of Scottish nobility, from the King down. Among the Scots dead were: the Archbishop of St Andrews, the king’s natural son, the Bishops of Caithness and the Isles, the Grand Prior of the Knights of St John, the Abbot of Inchaffray, the Dean of Glasgow, 9 earls (Argyll, Bothwell, Caithness, Cassilis, Crawford, Errol, Lennox, Montrose and Rothes), 10 lords, 113 knights and a large number of family heads and clan chiefs. - https://www.britishbattles.com/anglo-scottish-war/battle-of-flodden/

Sorry for the confusion here .... John Douglas, 2nd Earl of Morton died 9 September 1513 at the Battle of Flodden. -
