They remained at the convent for a year after their educations were complete, and made themselves extremely popular by enjoying themselves in society. Both girls soon caught the eye of two members of the Russian imperial family: Grand Duke Peter Nikolaevich, and George himself. On 16 April 1889 at Sergeyevsko Estate, George married Princess Anastasia of Montenegro, six years after Therese's death. Emperor Alexander III gave Anastasia a grand trousseau, as well as a considerable dowry.
