He was born in Adelebsen, from where his parents and brother were deported to Warsaw/Poland.
He had been at the Jewish orphanage in Dinslaken which was evacuated in 1938. Via Cologne he came to Holland.
Thank you very much for the information. Dutch records all mention Dinslaken as the place of birth. Do you have a (German) document which supports that Joachim Schaumberg was born in Adelebsen?
