Rozette van Praag, born in Amsterdam 11 March 1894, was a daughter of Zacharias van Praag and Hanna van Emden. She married Michael Machin in Amsterdam on 15 February 1917, a son of Hirch Machin from Minsk and Susanna Löwenstein from Enschede. Rozette and Michael had a daughter Susanna on 13 July 1918, but from this wedlock no other offspring was born; the marriage ended by a divorce on 12 June 1928.
Only 6 November 1941 Rozette van Praag remarried Hijman Oudkerk, a son of Meijer Oudkerk and Maria Cohenno. Hijman was previously married 25 March 1908 in Weesp to Elisabeth Rokkestikker, who passed away 6 January 1940. From the marriage of Hijman and Elisabeth two children were born: Meijer in 1909 and Jacob in 1917.
Since 20 November 1924, Hijman Oudkerk lived at Bilderdijkstraat 69 1st floor, where He runned his textile business at nr. 71. At the time of the mandatory registration of the Jews at the Jewish Council, Rozette van Praag and her daughter Susanna Machin lived at Tilanusstraat 13 ground floor in Amsterdam.
After Rozette married Hijman Oudkerk in 1941 she and her daughter Susanna from her first marriage, who worked as a maid, moved in with Hijman Oudkerk at Bilderdijkstraat. Susanna has survived the Holocaust and it appears from her archive card from the City Archive of Amsterdam, that she was registered 20 July 1945 as inhabitant of Ruyschstraat 124 in Amsterdam .
Rozette van Praag and her husband Hijman Oudkerk, probably in hiding, were after being betrayed, carried off 9 May 1944 to Westerbork and deported to Auschwitz 19 May 1944. This transport has been recorded in the so-called Westerbork film and arrived in Auschwitz 21/22 May 1944. On arrival Rozette and Hijman were immediately killed.
