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.
Alexander III of Scotland
Alexander died in a fall from his horse while riding in the dark to visit the queen at Kinghorn in Fife on 18 March 1286 because it was her birthday the next day. He had spent the evening at Edinburgh Castle celebrating his second marriage and overseeing a meeting with royal advisors. He was advised by them not to make the journey to Fife because of weather conditions, but he travelled anyway. Alexander became separated from his guides and it is assumed that in the dark his horse lost its footing. The 44-year-old king was found dead on the shore the following morning with a broken neck. Some texts have said that he fell off a cliff. Although there is no cliff at the site where his body was found, there is a very steep rocky embankment, which "would have been fatal in the dark." After Alexander's death, his strong realm was plunged into a period of darkness that would eventually lead to war with England. He was buried in Dunfermline Abbey.
