Please see the testimony of Von Rudolf Menacher und Hans-Ulrich Reiffen in the sources section of the linked profile.
I have just started to write this profile and am having difficulty understanding the section under "The deportation of the family of Isaac Meyer Sinzig" and hope that someone with more experience can help.
I believe the mentions of Charles and Carl both refer to Karl. The best I can get out of it is that Karl (whose family was Jewish) went to Catholic school for kindergarten and elementary school and was removed from school by a policeman in 1938. I don't believe anything in the rest of that paragraph applies to Karl. This document specifies Karl's death as "between 1941 and 1945", but it seems that, if my understanding is correct, the date should have been stated as "between 1938 and 1945".
If anyone can clarify the facts stated in this document, I would be most appreciative. Although my immdediate need is for the information about Karl, I will eventually be writing profiles for all the other people mentioned in the document.
EDITED TO ADD:
I realize that it is unlikely Karl had the wife currently listed and certainly the son listed for him, who was born in the late 1800's is not correct - this is what came in the original gedcom and I have not yet dealt with it!
