The marriage of Aron and Abigael did not last anymore. Presumably in 1939 in Amsterdam they have been divorced, after which Abigael da Cunha and her daughters moved to the François Valentijnstraat 91 in Den Haag and Aron Cosman to the Fultonstraat 113, also in Den Haag. Up from January 1940 Aron lived at the Oudemansstraat 330 and Abigael da Cunha and her three daughters in the Gerard Doustraat 33.
On 7 January 1944 Aron Cosman was carried off to Westerbork, registered there and ended up in the penal barrack 67. Whether he has been betrayed or that he committed an “offence” towards the German occupiers is unknown. But on 25 January 1944 Aron was put on a so-called “penal transport” to Auschwitz where on arrival there on 28 January 1944 he was immediately killed in the gas chambers of Auschwitz-Birkenau.
