Marie de Coucy
Alexander II died on 8 July 1249 during an expedition against the Lord of Argyll on the island of Kerrera. Immediately after the news reached her, Marie made sure her 8-year-old son was crowned as soon as possible at Scone. Although her son was a minor and was placed under regency, Marie did not become regent. On 9 June 1250 Marie and her son Alexander III were present in Dunfermline for the observance of the canonisation of Saint Margaret of Scotland and the transference of her remains to the new shrine.
John Ruthven, 3rd Earl of Gowrie
John Ramsay (afterwards the Earl of Holdernesse), noticing a small, dark stairway leading directly to the inner chamber adjoining the turret, ran up it and the door was then unlocked by Henderson. There he found the king struggling with Alexander. Drawing his dagger, Ramsay wounded Alexander, who was then pushed down the stairway past the king. Thomas Erskine, summoned by Ramsay, now followed up the small stairs with Dr Hugh Herries, and the two killed Alexander with their swords. John Ruthven, entering the courtyard with his stabler Thomas Cranstoun and seeing his brother's body, rushed up the staircase after Erskine and Herries, followed by Cranstoun. In the melée he was also killed. Some commotion was caused in the town by the noise of these proceedings but it quickly subsided, though the king did not deem it safe to return to Falkland Palace for some hours.
