Hello saylorlady, unfortunately I have only now become aware of your request for information about Willy Marxen.
I am his grandnephew. My name is Carsten. I live in Goosefeld, Schleswig-Holstein, Northern Germany.
Almost all of the information you mentioned fits exactly, with the exception of his place of birth.
My great-uncle Willy Marxen does not come from Norderstedt, but from Hollmühle, a small village near Schleswig.
Great-grandmother Margaretha (Greta for short) Marxen, born January 2, 1891 also lived there until her death (I remember 1972 or 1973).
I also knew “Aunty June” personally.
As long as great-grandma Greta was alive, June and Willy came to visit several times,
which they always combined with a camping holiday at Hahnenklee in the Harz Mountains.
When Great Uncle Willy died, I wrote "Aunty June" a letter of condolence, which she answered gratefully.
Address at that time: 4. Bankfield Drive, Leamington Spa, UK.
After that, contact unfortunately broke off.
And, as a schoolboy at the time, I made no further attempts to contact her.
I regret that today. Because I have fond memories of “Aunty June.”
I still own a photo of the house in Hollmühle that was sold after great-grandma Greta's death,
another 2 portrait passport photos of great-grandma Greta from 1960 and 1970.
I also have great-uncle Willy's so-called "work book" from the 1930s from great-grandma Greta's estate.
Such workbooks were mandatory in Germany during those days.
It states, among other things, the date and place of his birth: November 9, 1920, Hollmühle.
And it goes even further:
There is a copy of a certificate from 1908 about contributions to the pension fund
of Peter Erich Marxen. He was Willy's father, born February 9, 1871 (date of death unknown).
Great-uncle Willy's stepsister, Herta, (my paternal grandmother) lived from 1913 to 1988.
No other siblings are known.
Should you receive these lines after such a long time and if you are still interested, you can reach me via this portal.
Documents and photos would not be a problem via the Internet.
Looking forward.
Best regards, Carsten
