I'm interested in your comment that it could be unlikely that our Auten/Aten line comes from the Jewish connection because the general physical line is too short,square,blond, etc. to be of that genetic line.
Two thoughts.First, if the Aten line came from Portugal via the Semetic lands after the 1492 expulsions, there would have been time for at least 3 generations to marry into the blond Dutch gene pool before the move to America in 1650.This concentrated marriage pattern continued in America - the family tree was totally Dutch, Dutch/English, and German connected - so the blonding down of the Dark Semetic line would have gone on for several centuries.Is this enough time to obliterate the dark complextion, etc. of the Semetic?I'm not too concerned about the religious aspect, as the Sephardic Jews were known for their ability to 'fit in'.
Secondly, in my own family there was always a little mystery.My mother (an Auten) is short, has very dark skin, dark hazel eye colour, and black, wavy hair.All of her siblings and Auten relatives were blond, fair skined, and blue eyed.My mother was teased as a child - she had been left by the gypsies, etc.What an interesting thing if her colouring was a genetic flash back of over 400 years.We are able to look at the family tree all the way back to 1650, and there are no names that suggest anything but northern European genes from then until now.
These are all just thoughts, but there surely is material here for more than one thesis if there are geneticists out there who want to follow an interesting story back to its beginning.
