Map of L21 in France

[Tolan]

As there is no study on L21 in France, I decided to create a map from the participants in the different DNA projects on FTDNA. (U106, U152, L21 and DF27)
I counted the number of French, for each region (total 181), established percentages based on the percentage of R1b known for French regions.
Percentages are relative to the total of haplogroups
Thank you to be lenient on the method used! (Faute de grèves, on mange des merles! )


If my map is correct, L21 is curiusly present in Champagne and Alsace.
I think L21 comes from east, maybe this is the path taken for the first L21?

As a reminder, the map L21 by Eupedia:

Your map tend to indicate / confirm that L21 was not in the area of the 2 other groups. The empty area in the east is the place of U152 maximum. The north could be U106 but that is NOT what the Brabant study in Belgium suggested. U106 in the Brabant study was much more north. Unfortunately L21 was not tested in the Brabant study.
I am wondering what is the part of the computer in the gradient shown on your map. OK L21 strong in Britany. Since it's known that people from Cornwall invaded Britany at the time of King Arthur we can, wonder whether this maximum is really ancient.
My take would be that L21 was the first wave of P312 in France and it covered the whole country. Later, U152 started a conquest from the east. Also, it seems that some L21 in Normandy are coming from the vikings.
With the same data, can you tell what's the major group in the north of France according to these data ?

Yes, I think that

Also, it seems that some L21 in Normandy are coming from the vikings.

But i don't think that!

Effectively, I do maps for other haplogroups.
For the north, I find a strong presence DF27! Is this a bug or it's known?

Interesting maps. Thanks for sharing.

According to Semargl.me, France is currently showing 782 samples. Would there be any way to refine the map based on this website?

[alan]

was there not a recent study that showed more L21 than expected around NE France or Belgium?

About DF27 in the north of France I don't think it's known (I have long been one of the administrator for the project SRY2627, now also gathering DF27 testing from FTDNA). I am not very surprised but it's new. My take for DF27 is that it was the first spread of bronze age people along the atlantic coast (and main rivers). Some early settlements might have disappeared after other subgroups (like L21...) populated "France" (not yet called France).

To answer Alan , I think L21 and DF27 have been poorly tested ; they came after the Busby et al. study and too many people took it as the ultimate study.

Tolan, These are great maps. It has certainly improved my understanding of DNA in France. Is there enough data to map the SNPs below L21. I will try to do some data analysis in the next few days.
The DF27 map is interesting as it shows a hotspot emanating out of Iberia and SW France. The hot spot in the North is unusual.

Busby indeed provided L21 frequencies for some regions of France. They show as R-S145 and R-M222 in their tables.

With the same method, I made a map for Europe (excluding the British Isles).
Thank you to consider this as a rough draft!
I hope that more scientific studies arrive soon!
