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.
Prince Alexander of Hesse and by Rhine (1933–1937)
Some have considered the Hessian family victims of a family curse due to the number of premature deaths in the family. His orphaned younger sister Johanna, who had been left behind in Darmstadt, was adopted by their uncle Ludwig and his new wife Margaret Geddes, but died of meningitis in June 1939. Alexander was a great-nephew of Tsarina Alexandra and Grand Duchess Elizabeth Fyodorovna, both of whom were killed with family members during the Russian Revolution of 1917. His maternal great grandmother Princess Alice of the United Kingdom and a great aunt, Princess Marie of Hesse and by Rhine, both died of diphtheria. His paternal aunt, Princess Elisabeth of Hesse and by Rhine, died at age eight of virulent typhoid, though she was rumored to have eaten from a poisoned dish meant for Nicholas II of Russia. He was also a nephew of Prince Philip, Duke of Edinburgh.
