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.
Yakov Yurovsky
On the night of 16/17 July 1918, a squad of Bolshevik secret police (Cheka), led by Yurovsky, executed Russia's last Emperor, Nicholas II, along with his wife Alexandra, their four daughters–Olga, Tatiana, Maria, and Anastasia–and son Alexei. Along with the family, four members of the imperial household (court physician Eugene Botkin, chambermaid Anna Demidova, cook Ivan Kharitonov and footman Alexei Trupp) were also killed. All were shot in a half-cellar room (measured to be 25 feet x 21 feet) of the Ipatiev House in Yekaterinburg, a city in the Ural Mountains region, where they were being held prisoner. The firing squad comprised three local Bolsheviks and seven soldiers. It has been documented that the order to assassinate the Imperial family came from Yakov Sverdlov in Moscow and had been initiated by Lenin himself. It is also well documented that Yurovsky had visited the Bolshevik leadership in Moscow, and notably Sverdlov, only a few weeks before the killing took place.
