Sorry but that isn’t true, as the JewishGeneology has proven. So one man makes a mistake, it doesn’t fly with me. The names of his ancestors are also the names of many of the jews imprisoned during the holocaust. You can go look it up..sheesh. Even Hitler arrested those with the same name as his great grandparents and said they were jews...what more proof do you need.
Bill Ayers is a professor too, do you believe everything he says?
I don't doubt that. That's because, as I said, there are many surnames "owned" by both Jews and German non-Jews. Two people can share the same surname without any traceable common ancestors.
German Jews weren't persecuted during the Nazi era on the basis of their surnames. In most instances they or their parents had self-identified as Jews in national censuses taken by the previous regime, so the Nazis had a good idea who was Jewish even before they came to power. Additional Jews were identified by neighbors in the general civilian population who ratted them out to Nazi government bureaucrats.
This ratting out was also the most common way which the Nazis identified Jews in the nations they occupied.
I still challenge you to name an authoritative source which states that Hitler had Jewish ancestors. BTW, although Hitler did not, a few top Nazi officials did.
