Maciamo is just one of many blogger/poster guessing this, probably not even one of the first.
Read Diekenes (2010):
Of interest is the fact that while R-U152 has a clear French-Italian center of weight, the locations exhibiting highest STR variance are Germany and Slovakia, i.e., Central Europe.
My guess is that R-U152 originated in Central Europe spreading to the west and south, perhaps with Italo-Celtic speakers or some subset thereof. In its home territory of Central Europe, its frequency decreased by the introduction of the Germanic and Slavic speaking elements which dominate the region.
Irrespective of what the ultimate origin of R-U152 is, it provides us with a good diagnostic marker for population movements out of the French-Italian area. In Italy for example it is noted at 26.6% for the north and 10.5% in the south. It would be extremely interesting to see its occurrence in Balkan Vlachs, as this would confirm/disprove the Italian component in their origin.
However, R-U152 occurs in 7.3% of Cretans, suggesting introgression Y-chromosomes of North Italian (Venetian) origin, from the 4-century period of Venetian rule of the island. It also occurs in 4.1% of Greeks, where it might come from any period since the Roman annexation of the Hellenistic states to the Vlachs. However, its presence at only 1.8% of Romanians makes a large Italian contribution to the Romanian population unlikely. Balkan R-U152 chromosomes should be better resolved to determine when they arrived from the northwest.
The paucity of R-U152 in Turks (0.6%) make tales of wandering Galatians less likely to be true. There is no doubt that Galatians settled in Anatolia, but they were probably so few in numbers that they did not permanently alter the population. Knowledgeable readers should chime in
about the Lebanese Christian R1b which was posited as a signature of the Crusades a couple of years ago, and its position in the phylogeny.

But also read Tibor Feher Co-Admin of Kerchner's R1b Project, just guessing the same around 2010.

On the web you can find other poster/blogger/amateur geneticist starting from around 2010.
