No.
I think that there wasn't a single Norwegian family (parents with children) who were executed
for helping Jews. Of course, if someone proves that there was, I will admit that I thought wrong.
Here's an article about Polish family: father, mother (in advanced pregnancy) and six children,
who were executed for helping Jews.
After the start of the German occupation Jozef Ulma involved in helping Jews. Probably in the second half of 1942 adopted under its roof eight Jewish refugees from families Szall and Goldman [2]. In addition, another Jewish family helped build a dugout in the nearby woods, and then supplied its inhabitants with food and other products [3].
After some time, forest dugout was discovered by the Germans, and four of hiding Jews in it (three women and a child) were murdered. The fact that the provision of assistance to refugees by Ulma was not disclosed at the time [3]. The remaining eight Jews hiding in the farm Ulma the spring of 1944.
In the spring of 1944 Ulma's were denounced by the policeman, Wlodzimierz Les (from Ukrainian origin), who had seized the fortune of Szall family and wanted to get rid its respective owners. March 24, 1944 from German gendarmes which station in £ańcut killed Joseph Ulma, as well as his wife, which was in the ninth month of pregnancy and six children (8-year-old Stanislawa, 6-year-old Barbara, a 5-year-old Wladyslaw, 4-year-old Franciszek, 3-year-old Antoni and Maria eighteen-month). Together with Ulma's also all the Jews in hiding were killed.
