This sounds interesting. Could anyone tell me where such kind of blood analysis can be done? or what's its name? I'd like to try something similiar, here in Italy :) As for the question, Italy has always been a very mixed country. About Near-Est, just think of Spain. It ruled a large amount of Italy for a good deal of time, and Spain was once under Arab domain... ;) But this is just one of trillions of possible explanations ;)
Based upon the tests from Family Tree DNA (www.FTDNA.com) my Tullio ancestors came from the southern part of the so-called Fertile Crescent, perhaps the Jordan River valley. It's true that DNA analysis cannot say when they came to Italy or where in Italy they originally settled. I have followed their paper trail back to the mid-18th Century and at that time they were living in the Papal States, in towns like Veroli, Castro dei Volsci and Vallecorsa, towns which were not part of the Kingdom of Naples. Because of their likely point of origination in the southern Levant and the fact that most Europeans with my J1 haplotype are Jews, it's very possible that my ancestors were Jews as well.
