Coenraad Blog, born on 20 August 1865 in Amsterdam, was a son of Mozes Joseph Blog and Naatje Achsteribbe. He was a diamond cutter and married on 7 June 1905 in Amsterdam the 31-year-old Roosje Stodel, a daughter of Joseph Stodel and Elisabeth (Betje) Metz, who was also born in Amsterdam on 12 January 1874. Coenraad and Roosje had two children, namely Moses in 1906 and Joseph in 1916.
After they got married, they moved into a house at Camperstraat 28, moved to Rapenburg 20 in 1909 where they lived until 1926. Then they moved to Bertelmanplein 28. Their last move was on 21 July 1939 to Majubastraat 2 2nd floor in the Transvaalbuurt of Amsterdam East.
Their son Mozes married Lea Bierman in 1932, had a son Coenraad with her in 1934, but divorced Lea in May 1942, after which Mozes remarried in November 1942 in Camp Westerbork to Jette Peereboom. Their son Coenraad survived the Holocaust but Mozes self, his first and second wife were murdered during the Shoah.
Their son Joseph was a furniture maker by trade. He lived at home with his parents and remained unmarried. Joseph and his parents were arrested on 6 September and sent to Westerbork. They were to be put on transport on 14 September but already the next day, on 7 September 1942, Coenraad Blog, his wife Roosje Stodel and son Joseph Blog were deported to Auschwitz.
Joseph was 26 years old at the time and was one of the 110 deportees between 15 and 50 years of age who, during a stopover in Kozel, about 80 km west of Auschwitz, were forced to leave the train and subsequently to be deployed as forced laborers in one of the labor camps in that region. As for Joseph Blog, he ended up in labour camp Seibersdorf. Those who stayed behind on the train, including Coenraad Blog and his wife Roosje Stodel, were transported onwards to Auschwitz to be murdered on their arrival on September 10, 1942.
It is not known on which day exactly Joseph Stodel lost his life in Seibersdorf. After the war, the Dutch government, the Ministry of Justice, commissioned the municipality of Amsterdam to draw up a death certificate for Joseph Stodel, stating that he died in Seibersdorf on 31 March 1943.
