In terms of geno 2.0 (haven't checked ftdna) in terms of T-PF7443+ we have four individuals to work with here. Canary Islands, Campania (Caserta) Italy, a Sardinian and a German. I'm gonna go ahead and postulate a Phoenician link. La Palma (he westernmost canary island) had heavy Phoenician/Carthaginian influence from this same men that found Cadiz and Ibiza. The Sardinian is a rare Phoenician probably too, as is my marker (don't forget T is found at 18% in Sciacca Sicily, in the exact domain were the Phoenicians settled.) Marsala, Palermo, Selinunte, Pantelleria island, Erice, Favignana island, Aegadian islands, castellamare del golfo and cefalu were all Phoenician sites. We also know of a 7-8% high on the campanian coast and several central/north italian isolated cities have high frequencies as well. Same for 1-2 isolated pockets near Bavaria. A few regions of Spain and Portugal have interesting frequencies as well, although he spaniards lean towards Phoenician colonization whereas the Portuguese T1b signals are more in line with recent Jewish influence. It is not well understood why Chios has 25% T but it could be do to passing under Persian dominion and some studies on Aegean islands + Crete have found up to 33% T.
