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. Family and early life George's father Maximilian de Beauharnais, 3rd Duke of Leuchtenberg had traveled to St. Petersburg, eventually winning the hand of Grand Duchess Maria Nikolaevna, Nicholas I's eldest daughter in 1839. Maximilian was subsequently bestowed with the style Imperial Highness. As the son of a Russian grand duchess and an ennobled Russian prince Romanowsky, George and his siblings were treated as princes and princesses of the blood, bearing the styles Imperial Highness. After their father's death in 1852, Grand Duchess Maria morganatically remarried to Count Grigori Stroganov two years later. As this union was kept secret from her father Emperor Nicholas I (and her brother Emperor Alexander II could not permit the union, preferring instead to feign ignorance), Maria was forced into exile abroad. Alexander felt sympathy for his sister, however, and paid special attention to her children from her first marriage, who lived in St. Petersburg without their mother. Marriage Marriage to Therese On 12 May 1879, George married Duchess Therese Petrovna of Oldenburg, a daughter of Duke Peter Georgievich of Oldenburg and Princess Therese of Nassau-Weilburg. Therese's elder brother Duke Alexander Petrovich had been married to George's sister Princess Eugenia Maximilianovna since 1868. Therese's grandfather had married Grand Duchess Catherine Pavlovna, daughter of Paul I of Russia, and their descendants had been raised in Russia ever since and become completely "Russianized", much like George's own family. Thus, despite her German title, Duchess Therese, like her father before her, had grown up entirely in Russia. She was always considered a part of the Russian imperial family. George and Theresa had one son: Alexander Georgievich, 7th Duke of Leuchtenberg (13 November 1881 - 26 September 1942); morganatically married Nadezhda Caralli. In July 1881, the British Reserve Squadron held entertainments on board , which was stationed in Cronstadt. The luncheon was attended by Therese and her husband, as well as the Emperor and Empress and other important royal Russian and German figures. Two years later, on 19 April 1883, tragedy struck the couple when Duchess Therese died in St. Petersburg. Marriage to Anastasia Two Montenegrin princesses, Milica and Anastasia, were educated at the
