Frieda Gerson from (Bad) Sobernheim in Germany, married Samuel Louis Cohen, who was born in Rotterdam, a son of  Louis Samuel Cohen and Clara van Dam. The couple had two daughters: Rose Clara, who was born in Brussels in 1911 and Betty, born in 1914 in Den Haag.  About Rose Clara, who was married 18 August 1938 to Salomon de Vries from Rotterdam, is further nothing known. Presumably both might have survived the Holocaust. Frieda's daughter Betty and her husband David Samuel Polak, have been killed on 23 September 1943 in Auschwitz. Frieda self and her husband Samuel Louis Cohen were killed both on 14 May 1943 in Sobibor.
