Marianne Koch(I)

After the birth of her two children, Marie Aumüller married Rudolf Koch. Her children took the name of their stepfather. Although the marriage of Rudolf and Marie Koch was short-lived, the children did not know the identity of their biological father, Rudolf Schindler, a well-known gastroenterologist, until much later. He was a Jew, so the fact that he hadn't been identified as the father of Marie Koch's children may explain how they survived the Shoah. In 1934, Schindler was forced to emigrate from Germany with his wife, Gabriele Winkler, and their two children Richard and Ursula. After Gabriele Winkler's death, Rudolf Schindler married Marie Koch.
