My father died before I got into this whole topic, and my father's brothers and sisters as well (he was much older than my mother), so the only people I could test are my older relatives in Italy, but they won't do it, even after I've offered to pay and other bribes as well.
All I can go on are my own results. On the old Dienekes calculators, my scores on the "components" were consistently in between the ones for Bergamo and the ones for Tuscans, with perhaps a slight "lean" on some of them toward Tuscans.
I'm not surprised that there would be a difference between West Emilians and Tuscans: the Appennini are right smack between the two areas. Yes, there are passes, passes which have been used since time immemorial for trade and later as a pilgrim route (the Via Francigena). However, I doubt there was mass mingling. It's the same way the Alps functioned in northern Italy, and why as far back as Novembre et al there's a slight break in the European cline there, although not as large as the one south of Rome.
In addition, the area from which my father's family came had no roads until almost 1920. It was mule tracks before that. That isolation, and the fact he was teaching in Parma is why Cavalli-Sforza did all his work there, especially his book on Consanguinity.

I can't believe they're charging that. It's available elsewhere for much less. I'm not so sure any longer that the differences from the plain are just the result of drift. I have a feeling that the people on the plain may have changed somewhat due to later admixture, although there is drift from village to village. Some villages are much more "fair" in coloring than others, for example.
That's the reason I started a thread on those people. They've all but disappeared. I wanted to memorialize them, even if my sense of identity is with my mother's people, among whom I was raised. There's some nonsense in the middle, but in the beginning and the end there are good pictures of them, members of my family included.
