Yad Vashem Testimonial states Hans F. lived in Berlin and had a son Günther; Günther Frank (17.12.1924) is listed in the Berliner Gedenkbuch at Kaiserdamm 74 in Berlin-Charlottenburg, which has Hans F. at the same address in the Berlin Addressbook of 1938. The Yad Vashem Testimonial also states that the mother of Günther was Olga nee Tauber, and that she and Hans were divorced.
