Isn't the area of the present day Kurds the area where the Assyrians took the Northern Tribes...I think Mosul is the same as Nineveh(sp). Your ideas?
It's the same general area. I haven't heard that Ninevah is Mosul, but I wouldn't be suprised.
The genetic connections between Kurds and Jews are strong-- but Kurdish bares no relation to Hebrew or Aramaic, and you don't find many cultural markers linking the two groups. So I personally think it's more likely that the genetic connection arises because Kurds originate from the same area as Abraham-- i.e. Abraham was likely a proto-Kurd before he became the first Hebrew.
Still, given the genetics, it's far more likely that the Kurds would be descended from the "lost" tribes than the Celts or any Europeans.
