Ah yes, nothing like a little DNA profiling is there?
Find it, define it and seperate from the rest.
Isn't DNA research great? Tends to remove all doubt of ancestry. I wonder what the "percentage points" will be.
No hiding then...flight from oppression by many gg grandparents is futile in the face of new technology.

I'm sorry: I'm afraid I have absolutely no idea what you just said.

You mentioned the second diaspora and I mentioned a way in which it could be brought about. Many people of Jewish descent are outrightly known while others have only surnames to indicate a possible Jewish ancestry. Would a third generation grandparent with the name Jacobs qualify one as "Jewish"? DNA testing could find out with some certainty.
With the cross marriage of many of known Jewish ancestry there is a large portion of the population that has only partial Jewish ancestry, "half-breeds" if you will. Many simply have no idea if their ancestry is "Jewish" or not. I would imagine that a large number of families never mentioned it simply in a desire to "fit in".
My reply was a somewhat facetious attempt to explain how a second, more thorough and complete, diaspora could be accomplished...DNA sampling. What would cause it to occur is a different subject.
