In the E3b project of Haplozone this cluster is E1b1b1a2-B. There are six members, among them Galliano from SMGF I put on Ysearch as E4U93 (Cellier, Galliano, Junod, Ramondino, Schiffley, Willoughby): 3 are from Switzerland, 2 from Italy, one from Ireland. If we add the two Italian guys tested by Picornell who are on YHRD and a new Italian from SMGF (Villano), it is clear that Italians are the most part and we can hypothesize that this cluster was born in Italy.
Vadim Urasin (Geograficeskoe otnesenie nekotoryx vetvei filogeneticeskogo dreva E1b1b1a2-V13, in RJGG, 2009, 17-22) says that this cluster was born during the 11th century BC. We don't know if these datings a la Klyosov are reliable (I personally have always doubted), but clearly this cluster demonstrates once more an irradiation from Italy to Switzerland and the British isles. The fact that we find it in Ireland should make us think to a more ancient time, probably of some thousands of years.
