Rosa Samish, Gidon's great-grandmother was put on a transport from Prague to Terezin, where she spent two months. Rosa later perished in a gas chamber at Treblinka. ​​

Fritz Samish, Rosa's son, and Gidon's maternal grandfather was a bank manager and had served in the Austro-Hungarian army during the First World War. He has transported to the Warsaw Ghetto just weeks ahead of the Nazi "Grosse Aktion" in which 25,000 Jews were sent to Treblinka. ​

Doris Löw, Gidon's mother, pregnant with Gidon in this photo, survived four years in Terezin as a slave laborer. She survived the camp and later moved to Canada. She passed away in Israel in 2003.​

Ernst Löw, Gidon's father, was a slave laborer in Terezin for four years before he was put on a transport to Auschwitz and tattooed as prisoner B12156. Two weeks before Auschwitz was liberated on January 27th, 1945, Ernst was sent on a death march to Buchenwald. He never arrived.
