I made some tel.calls and find out that Karen was Born on 17th of oct. but 1917 in Malente.
She married 1968 in a City called Preetz again.
So I called to the "Rathaus" in Preetz and asked them to search for the marriage, also
I have contact the "Rathaus" in Brunsbüttel for her childrens.
The People in Malente told me that they have to dead certificate for Karen, so it can be that Karen
is still alive, that I will check out.
