In 1940, Abraham and Sarah Grubstein, accompanied by their children Maurice, Jacques and Nadia fled to the free zone, in southern France, just before the Germans took over all of France.
They were arrested several times, sent to a detention camp, and eventually made it to in the Tarn District.
The family was referred to Reverend Cook, who in turn sent them to his colleague Reverend Marcel Ducommun in the village of Senegats.
They were provided shelter from the Nazis by Pastor Marcel Ducommun, a member of the French resistance movement, and his wife Helene Marthe, hidden inside the church compound with free access to the parsonage.
They hid for two years, and because of Pastor Ducommun's care, the whole family survived.
On December 21, 2009, the Commission for the Designation of the Righteous Among the Nations at Yad Vashem recognized Pastor Marcel Ducommun Ducommun, and his wife Helene Marthe, as Righteous among the Nations.
After the war, the Grubsteins became French citizens and Francizied their name to Grubain.
