Sientje Bosboom was a daughter of Mozes Salomon Bosboom (a son of Salomon Mozes Bosboom and Annaatje Barend Kroese), and Vogel van der Glas (a daughter of Joel Jesaijas van der Glas and Schoontje Jochem Hes). Sientje’s parents were married in Amsterdam 16 August 1865.
18 December 1895 she married in Amsterdam Lucas Dreese, a son of Abraham Dreese and Schoontje Cohen. The couple had four children, namely Jeannette, Abraham, Maurits and Vogelientje. Jeannette and Abraham were killed in the Shoah, just as their parents. The other two children have survived the Holocaust.
Sientje was born into a family with seven children of whom she self, Jesaia, Klaartje and Heintje were killed in the Shoah. Her brother Salomon died in 1923 and her brother Joel passed away in 1939. Presumably her brother Emanuel survived the war.
Since October 1938 Sientje Bosboom resided with her husband Lucas Dreese at Courbetstraat 31 down floor in Amsterdam. Also Sientje’s daughter Vogelientje lived there, together with her spouse Meijer Polak and her in 1939 born daughter Renee Beatrix. Before, they all lived at Eerste Helmersstraat 114 down floor.
Sientje's husband Lucas Dreese however was already arrested in September 1942 and he was deported from Camp Westerbork to Auschwitz on 18 September and three days later on 21 September 1942 upon arrival there immediately killed.
Sientje Bosboom self was arrested 4 November 1943 in Amsterdam. She was not wearing the yellow “Judenstern” (Jew star) and she carried a falshed ID. Her son-in-law Meijer Polak, a son of Nathan Meijer Polak and Rebecca Plotz, his wife Vogelientje Dreese and her granddaughter Renee Beatrix were gone into hiding in Amsterdam. But except Vogelientje, Meijer Polak and his daughter Renee Beatrix were arrested that same 4 November at Kinkerstraat in Amsterdam; they did not wear the yellow “Judenstern” either and carried falshed ID’s too. 6 November 1943, Sientje and Meijer were sent to Camp Westerbork as “criminal cases” and also Renee Beatrix, 4 years old, was sent there too. They stayed in penal barack 67 untill they were deported to Auschwitz on 16 November. Upon arrival there on 19 November 1943, Sientje Dreese-Bosboom and her granddaughter Renee Beatrix Polak were immediately killed. Meijer Polak however had to work in hardship about four months and he got killed there on 31 March 1944.
Sientje’s son Maurits was emigrated to New York in January 1940 and did not experience the Holocaust. On 31 October 1942 a letter arrived for Lucas Dreese through the Red Cross from his son Maurits Dreese, 68-38 Yellowstone Blvd, Forrest Hilles (L.I.) New York. However, Maurits’ father was not in Camp Westerbork anymore at that time as he was killed in Auschwitz already 21 September 1942.
Also Sientje’s daughter Vogelientje Dreese has survived the Shoah. She too went into hiding. According data from her registration card of the Jewish Council, she was exempted from deportation (“gesperrt”) because of “weermacht”(army force). Among others, she was a teacher physical education (gymnastics) and because of that she stayed at the “Rijks Opvoedingsgesticht” in Maarsbergen. (a borstal). According notes at her registration card she contacted the foster parents of her daughter Renee Beatrix at M.H. Trompstraat 12 in Amsterdam on 28 November 1946.
As a single woman, she is at age 41 on 20 December 1946 emigrated from Rotterdam to New York with the S.S. Westerdam (Holland Amercia Line).
