Hello and sorry that this is VERY vague..!

I am trying to find a PECK family who had a farm during the Second World War on which at least one German prisoner of war was given work. Mrs Peck's first name was ROSE.
The POW in question was Emil Lautenbach, born in 1913 in Hamburg.
He was taken prisoner in France, seriously wounded with bullet wounds to the chest/stomach. He was later transported to England, where he worked on a farm owned by the Peck family.
The family treated him extremely well. They even insisted on having his much younger brother Gustav (the lad was around 12 years old) sent to them after the war, so that they could care for him for a while and provide him with enough to eat.
The Lautenbach family were so grateful to the Pecks that Emil and his wife named their daughter Birgit Rose, born 1948, in honour of Mrs Peck.
They even pronounce "Rose" in the English way, instead of the German "Rosa".
I have lived in Germany for 30 years. We moved last year and Birgit is now our landlady - and an absolutely wonderful person. I don't know if it is the fact that she now has a Brit living next door

, but she would love to find out more about the Peck family.
Her father and uncle are both deceased and no family records, photos, etc. exist from that time. Birgit does not know how to start looking, so I suggested that I try to help.
I realise that our "information" is extremely sparse, but maybe it rings a bell with someone. Die Hoffnung stirbt zuletzt (hope dies last), as the Germans say.
I would be extremely grateful for any information whatsoever, however insignificant it may seem.
Many thanks in advance,
Karen
