Hello!
Youngest sister of Kaiser Wilhelm's second wife Hermine, Princess Ida, was married into the Stolberg-Rossla Princely family. She was married to the 3.Fürst zu Stolberg-Rossla, Christoph Martin. They had four children, two daughters and two sons.
The youngest son, Johann Martin became the 4.Fürst zu Stolberg-Rossla. He was married to Hildegard Sauerbier, but they apparently didn't have any children. Who succeeded as 5th Fürst zu Stolberg-Rossla? Or this Princely family was annexed into some other branch of Stolberg family.
Thanks in advance.
