Heinz Kornfeld was born in Beuthen (now Bytom) on 23rd August 1911.
At the start of the war Heinz was living in Berlin with his wife Margot (Werner‘s cousin) and baby daughter Reha. The whole family was deported to Theresienstadt on transport I/104 in 1943, yet they all survived the war.
At some point it seems that Margot and Heinz divorced, and eventually Margot left Germany for New York with their daughter, in 1949.
I do not know what became of Heinz.
