Hendrika Mok, daughter of Isaac Aron Mok (1845) and Jeannette Natkiel (1847), married Isaäc Boeken on 24 May 1893 in Amsterdam, a son of Coenraad Boeken (1841) and Hendrika Mok (1842). As far as could be verified, this couple had no children.
Isaäc Boeken worked as a fruit vendor, as diamond cutter and as a loos laborer. He lived with his wife Hendrika Mok at Valkenburgerstraat 210, at Ruyschstraatr 16 and after another five relocations they lived at Nieuwe Kerkstraat 135 in Amsterdam, their last known address.
On 4 March 1943,they were both registered in Westerbork and for unknown reasons locked in the penal barrack 67 and deported with the 2nd transport to Sobibor on 10 March 1943. On arrival there on 13 March, Hendrika Mok and Isaäc Boeken were immediately killed.
