[1] 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.

[7] George and Theresa had one son: In July 1881, the British Reserve Squadron held entertainments on board HMS Hercules, which was stationed in Cronstadt.

[9] Both girls soon caught the eye of two members of the Russian imperial family: Grand Duke Peter Nikolaevich, and George himself.

[10] When still married to his second wife, George moved in with his French mistress, to the great anger of the morally rigid Emperor Alexander III.

[11] When told that George was spending his vacations at the coastal town of Biarritz in south-western France, Alexander declared "So the prince is washing his filthy body in the waves of the ocean".

She and her sister became famous in Russian society as the "black peril" so called because of their home country of Montenegro, their dark complexions and their interest in the occult.

[14] At the turn of the twentieth century, when still married to Princess Anastasia of Montenegro, George was considered as a possible successor to the childless Alexander I of Serbia.

George inherited a large collection of paintings, sculptures, and other works of art from his father, who had brought them with him when he moved from Munich to St. Petersburg to marry Grand Duchess Maria Nikolaevna of Russia.
