Mietje Droomer was the eldest daughter of Benjamin Droomer and Jetje Wallig. Mietje was born on 9 June 1889 in Rotterdam. Her father, born in 1864 in Sommelsdijk, arrived already in 1874 with his parents in Rotterdam. Her mother was born in Den Haag in 1864 and she married Benjamin Droomer in Rotterdam on 16 November 1887, who already passed away in 1904. Jetje Wallig passed in 1938.
In the Droomer family there were born seven children, of whom one stillborn son in 1895. Mietje further had one sister in 1891, Helena and another four brothers, namely Nathan in 1893, Mozes in 1894, Jozeph in 1897 and Izaak in 1900. Jozeph Droomer died already in childhood in 1900, almost 3 years old. Izaak married a non-Jewish woman in 1933 and because of his mixed-marriage, he probably survived the war. The other Droomer children from the family were all murdered during the Shoah.
Mietje Droomer married twice Andries Kalkoen in Rotterdam, a son of Abraham Kalkoen and Elisabeth van Loon, but divorced him twice too. Out of her her first wedlock on 28 September 1910, two children were born: Elisabeth and Benjamin. Both have died at young age: Elisabeth aged 22 in 1934 and Benjamin in 1928 at the age of 14 years. Mietje divorced Andries in March 1922, but married him again in April 1924, after which again a divorce followed in 1933. Andries Kalkoen married then a non-Jewish spouse and survived the war.
Mietje married then the 3rd time the widower of Henriette Katan, the shoemaker Marcus Cohen, who was born 26 September 1880 in Heinenoord as son of Mozes Nathan Cohen and Sophia Blok. Marcus became widowed in 1935 and his wedding to Mietje Droomer then followed in Rotterdam on 29 April 1936.
That 29th April 1936, Mietje Droomer and Marcus Cohen lived at Weenaplein 5c in Rotterdam, moved to Diergaardelaan 62b in 1938 and presumably after the bombing of Rotterdam on 14 May 1940 they moved into house at Voorschoterlaan 112b in the Kralingen district of Rotterdam. From there they offered living space via “Het Joodsche Weekblad” (Jewish Weekly) by advertising a secluded bedroom and homely relations to a lady or gentleman. From there, they have been taken early October 1942 via “Loods 24” to Westerbork and deported to Auschwitz on 12 October. On arrival there on 15 Ocbober 1942, they were both immediately killed in the gas chambers of Auschwitz-Birkenau.
