Not really, I'm aware that many variables like sample size, the size of the population of the sample places, even genetic drift and so on could influence the final results, and yes, we need more studies. I just see no reason to dismiss the trend until now given the current data.

Few samples indeed, but it is in accordance with modern trends of FTDNA, especially if we take into account that most of these DF27 Iron Age samples were found in the North or close to it.

I doubt, to be honest. Despite small, It is also confirmed by Iron Age samples, and the genetic landscape of France didn't change that much since then, it seems. I remember seeing a map on anthrogenica with the same results of Maciamo using many FTDNA samples.

It looks like Maciamo's code is in HTML language. Here's the converted table with the results:

The first post of this thread showed a table with frequencies of the main subclades of R1B (R1B-L21, R1B-DF27, R1B-U152, R1B-U106 and so on) in France, basically. R1B-DF27 was common both in the South and the North, R1B-L21 was most common in northwest (as expected) and R1B-U152 in the east...

Well, if that data presented by Maciamo in this post and these 1902 samples are not enough to prove that R1B-DF27 is common all over France, I don't know what could be. I mean, it is not only common in the south but also in northern provinces. Even where it is not the most common, it tends to be...

Maciamo published many samples from that 2022 study about Iron Age Gaul in Eupedia with the their respective Y Haplougroups. The two most common were R1B-DF27 and R1B-L21, with 4 each. 3 of these R1B-DF27 were found in more northern provinces, and only 1 in the south. And it kind of makes...

Indeed. If I am not mistaken, the main study about it was published in April of 2022, but it was focused on the origin and mobility of Gauls in France, and that clade (DF27) was dominant in French Gaul. I don't know why French Gauls differ from Italian ones in that respect tbh 🤔 If I'm not...

Just a correction though: the percentage of native european autosomal DNA among Iberians is between 90% and 100% (the rest is residual), and around 50% (from Bell Beakers and Iron age Celts) of that ancestry is NW European already, being the remaining 40% Iberian Neolithic Farmers and European...

Nah, R1B-DF27 is more like an Ibero-Gaulish clade now, and very important among Celts. In fact, recent studies about Iron Age Gauls also showed that R1B-DF27 was dominant among them.

Not related to this specific haplogroup, but anyway: there' an interesting fact: the haplogroup R1B-U106 of NW European origin (Germanic) is overrepresented in the Azores, compared to other Iberian populations. According to the paper which contained that information: "There is a strong bias...
