Haplogroups of Italy

Using a variety of sources (cited below), I have compiled an estimate of Y-DNA haplogroup frequencies in Italy. Because the sources examined different haplogroups (often with a variety of nomenclature systems) in different geographies within Italy, some extrapolation and adjustments were necessary.

Still, I think having these estimates compiled in one location will be useful to the participants in the Italy DNA Project. For reference, I have compiled the observed frequency of each haplogroup for our project's current participants.

Is it possible to find an haplogroup frequency by region, Marche and Lazio ?
Does an haplogroup frequency tabel exists for pre-roman populations ?
best regards RM
