 Princess Carolyne lived with Liszt during his years in Weimar.She eventually wished to marry Liszt, but since she had been previously married and her husband, Russian military officer Prince Nikolaus zu Sayn-Wittgenstein-Ludwigsburg (1812–1864), was still alive, she had to convince the Roman Catholic authorities that her marriage to him had been invalid.After huge efforts and a monstrously intricate process, she was temporarily successful (September 1860).
