The HGDP samples were chosen by Cavalli-Sforza, and I think he chose to sample in southern Tuscany because he wanted samples from the more heavily "Etruscan" areas.
The rest of the Tuscan samples are confusing in terms of the source because of variable labeling. On K12b Dienekes uses that Tuscans(HGDP) sample, and then a TSI30 sample. He doesn't label the source for TSI as HapMap. He labels the source as Metspalu. I'm much closer in terms of fit to the TSI sample than to the Tuscan sample.
On the dv3 that's the subject of this thread, he uses all four Tuscan samples and labels TSI as Hap Map. Again, I'm closest to that sample. The other three are HGDP, Henn, Zing in that order. They all cluster in one group. The samples are labeled in terms of source, so New Englander should know the order.
I think you're right that really there are only 2 samples: HGDP from southern Tuscany, and TSI Hap Map, which I believe was taken from a village northeast of Firenze. Henn and Zing are just subsets of Hap Map.
I also looked at the population averages for a few of the calculators, and the TSI group is often 2 or 3 points less "Caucasus", for example, than HGDP. The Italian cline is always there, even within an individual province.
Dienekes really knew what he was doing. Too bad he lost interest.
