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.
Grand Duke Dmitry Konstantinovich of Russia
On 1 June 1880, Dmitry Konstantinovich was appointed to the suite of Alexander II and given the rank of Fligel-Adjutant. Six months later, after completing his initial infantry training, the grand duke was appointed lieutenant in the Horse Guards Regiment. He was to serve with the Horse Guards for twelve years as a junior officer, and finally as commander.
After completing a training course with the General Staff Academy in 1880, Dmitry Konstantinovich was promoted to Ordnance Officer and scheduled to make his first official appearance, when he would deliver the report as an Imperial Adjutant in the Guards Sappers Cavalry Regiment. The date for his first appearance was Sunday, 1 March 1881. Two hours after the review, his uncle Alexander II, who had been present at the insistence of Alexandra Iosifovna, was assassinated.
