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.
Attalus (general)
After Philip II had been assassinated and Alexander became king (October 336 BCE) his stepmother Cleopatra Eurydice and her two children were all killed (Cleopatra Eurydice may have died by her own hand after the murders of her children).
