Who knew Kurt and Rosa Sommerfeld?

I would like to ask if someone ever knew Steven Summerfield’s parents Kurt and Rosa Sommerfeld, who, as far as we know, died in Auschwitz in 1942. Their last letter from Berlin (no other address given) to Steven, their only child, was dated 7.12.1941 when they hoped to join him soon in England. This letter is the only memento we have of them, everything else was lost or destroyed but it is just possible there is someone, somewhere, who remembers them and could tell us something about them. If so, it would be good to hear from them.
