Princess Hermine was married on 7 January 1907 in Greiz to Prince Johann George Ludwig Ferdinand August of Schönaich-Carolath (11 September 1873 – 7 April 1920).They were the parents of five children: In January 1922, a son of Princess Hermine sent birthday wishes to the exiled German Emperor Wilhelm II, who then invited the boy and his mother to Huis Doorn.Wilhelm's physician, Alfred Haehner, suspected that Hermine had married the former kaiser only in the belief that she would become an empress and that she had become increasingly bitter as it became apparent that would not be the case.She cared for the property management of Huis Doorn and by establishing her own relief organization, she stayed in contact with monarchist and nationalist circles in the Weimar Republic.After the end of the Second World War, she was held under house arrest at Frankfurt an der Oder in the Soviet occupation zone, and later imprisoned in the Paulinenhof Internment Camp.
