Qui es va casar amb Princess Anastasia of Montenegro?

Princess Anastasia Petrović-Njegoš of Montenegro (4 January [O.S. 23 December 1867] 1868 – 25 November 1935) was the daughter of King Nikola I Petrović-Njegoš of Montenegro (1841–1921) and his wife, Queen Milena (1847–1923). Through her second marriage, she became Grand Duchess Anastasia Nikolaevna Romanova of Russia. She and her sister "Militza" (Princess Milica), having married Russian royal brothers, were known colloquially as the "Montenegrin princesses" or the "Black peril" during the last days of Imperial Russia, and may have contributed to its downfall by the introduction of Grigori Rasputin to the Empress Alexandra.

Prince George Maximilianovich Romanowsky, 6th Duke of Leuchtenberg (29 February 1852 – 16 May 1912), also known as Prince Georgii Romanovsky or Georges de Beauharnais, was the youngest son of Maximilian de Beauharnais, 3rd Duke of Leuchtenberg and his wife, Grand Duchess Maria Nikolaevna of Russia.

Grand Duke Nicholas Nikolaevich of Russia (Russian: Николай Николаевич Романов (младший – the younger); 18 November 1856 – 5 January 1929) was a Russian general in World War I (1914–1918). The son of Grand Duke Nicholas Nikolaevich of Russia (1831–1891), and a grandson of Emperor Nicholas I of Russia, he was commander in chief of the Imperial Russian Army units on the main front in the first year of the war, during the reign of his first cousin once removed, Nicholas II. Although held in high regard by Paul von Hindenburg, he struggled with the colossal task of leading Russia's war effort against Germany, including strategy, tactics, logistics and coordination with the government. After the Gorlice–Tarnów offensive in 1915, Tsar Nicholas replaced the Grand Duke as commander-in-chief of the army. He later was a successful commander-in-chief in the Caucasus region. He was briefly recognized as emperor in 1922 in areas controlled by the White movement in the Russian Far East.
