What did your fiance claim the Hohenzollerns did during the war? The Nazis had little use for the Hohenzollerns and the Hohenzollerns had little use for the Nazis! That's why Kaiser Wilhelm II's 1941 funeral in Holland was kept so low-key. See the following web page:

I would suggest you simply contact Prince Georg Friedrich, the current head of the family, for additional information about other Hohenzollern descendants. If your fiance is a member of the Hohenzollern family, he must know Prince Georg Friedrich:

And how do the Rundstedts supposedly fit into all this? Am I correct in assuming that you're referring to the family of Field Marshall Gerd von Rundstedt (1875-1953) of World War II fame? The Rundstedts go back more than 700 years. Their ancestral home is in the region known as the Altmark, which is located in the northern part of today's German state of Saxony-Anhalt. Although the Rundstedt family stood in the service of the reigning Hohenzollerns down through the centuries, they were in no way whatsoever related to them. (Gerd von Rundstedt was very apolitical. He could in no way be ranked as a Nazi.)
