Moïse Kagan, a Russian student, was sentenced to internal exile in Siberia as punishment for his political activism. After serving his prison term, he emigrated to Belgium, where he continued his engineering studies at the University of Liège. Moïse’s wife, Sonia Levine, followed him in 1912. The couple sought refuge in Lithuania during the First World War, where Sonia gave birth to a daughter, Lydie, in 1916. The family returned to Liège in 1923. Moïse found employment as an engineer in a zinc plant, while his daughter Lydie trained as a pharmacist.
When the Second World War broke out, the Kagans fled to France. They settled in Blajan, but were detained and placed in the Noé internment camp. The family was deported from the Drancy assembly camp via Transport 28 to Auschwitz-Birkenau on 4 September 1942. There is no further trace of Moïse Kagan (53) or Sonia Levine (50). There is a possibility that Lydie Kagan (26) was spotted in Birkenau in June 1944, after which she too disappears from the records. None of the family members survived deportation.
