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.
Macedonia (ancient kingdom)
When Philip II married Cleopatra Eurydice, niece of general Attalus, talk of providing new potential heirs at the wedding feast infuriated PhilipII's son Alexander, a veteran of the Battle of Chaeronea, and his mother Olympias. They fled together to Epirus before Alexander was recalled to Pella by PhilipII. When PhilipII arranged a marriage between his son Arrhidaeus and Ada of Caria, daughter of Pixodarus, the Persian satrap of Caria, Alexander intervened and proposed to marry Ada instead. PhilipII then cancelled the wedding altogether and exiled Alexander's advisors Ptolemy, Nearchus, and Harpalus. To reconcile with Olympias, PhilipII had their daughter Cleopatra marry Olympias' brother (and Cleopatra's uncle) AlexanderI of Epirus, but PhilipII was assassinated by his bodyguard, Pausanias of Orestis, during their wedding feast and succeeded by Alexander in 336BC.
