question:
Where did the Grynszpan family live after Hanover?, Context: After 1937 the Lord Mayor and the state commissioners of Hanover were members of the NSDAP (Nazi party). A large Jewish population then existed in Hanover. In October 1938, 484 Hanoverian Jews of Polish origin were expelled to Poland, including the Grynszpan family. However, Poland refused to accept them, leaving them stranded at the border with thousands of other Polish-Jewish deportees, fed only intermittently by the Polish Red Cross and Jewish welfare organisations. The Gryszpan's son Herschel Grynszpan was in Paris at the time. When he learned of what was happening, he drove to the German embassy in Paris and shot the German diplomat Eduard Ernst vom Rath, who died shortly afterwards.

the border
