Only seven words of that (the link title) were mine, after all. I merely thought it would make an interesting topic of conversation, not knowing it was such a contentious issue. The Telegraph seemed reliable enough to start a CMB thread. Were I writing a book on the subject I certainly would have done more research than what goes into posting a casual thread in the wee hours of the morning on the way to bed.

I am actually more interested in how a DNA test proved Hitlers grandfather was not Jewish, since centuries before Hitlers birth there were already millions of Jews without a drop of Hebrew blood. A DNA test would probably show much of Israel is not Jewish. The test might be useful in the context of Hitlers ideas of racial purity, except those ideas were fallacious in the first place (and practically pointless in the '30s and '40s given that DNA had not been discovered yet, let alone DNA tests.)
