Simply so, how did Maria Rasputin die?
Heart attack
Similarly, what was Rasputin poisoned with? On the night of December 29, 1916, a group of conspirators, including the czar's first cousin, Grand Duke Dmitri Pavlovich, and Prince Felix Yusupov, invited Rasputin to Yusupov's palace and fed him wine and cakes laced with cyanide. Though Rasputin eventually became rather drunk, the poison seemed to have no effect.
Consequently, are there any descendants of Rasputin?
Laurence Huot-Solovieff, who grew up in France, is the only one of Rasputin's surviving descendants to have visited Russia, the St. Petersburg Times reports. Rasputin, a mystic, became a favorite of Czar Nicholas II and his wife, Alexandra, because they believed he could treat their son's hemophilia.
Are there any Romanovs left?
At the time of the executions, about a dozen Romanov relatives were known to have escaped the Bolsheviks, including Maria Feodorovna, the mother of Czar Nicholas II, her daughters Xenia and Olga, and their husbands. Of the 53 Romanovs who were alive in 1917, it's estimated that only 35 remained alive by 1920.
