In his book **Semi-Imperator**, genealogist **Wilhelm Pickl von Witkenberg** claimed that the Hohenzollern family had Jewish blood. 

I understand this claim is highly unlikely. Nevertheless, it has aroused my curiosity. 

Clearly the official Wilhelm II's family tree, so to speak, does not include any Jewish connections, unless you consider ancestors such as Ferdinand II of Aragon or Elizabeth of York, who apparently did have Jewish origins.

Does anybody have the Emperor Wilhelm II's family tree built by Pickl von Witkenberg?
