Here are the results for Northern France versus Southern France.
Northern France (N = 18)
L21+ (L21 Positive) = 11 (61%)
L21- (L21 Negative) = 7 (39%)
Southern France (N = 2)
L21+ (L21 Positive) = 1 (50%)
L21- (L21 Negative) = 1 (50%)
Four of the subjects have ancestry in France but cannot name the exact
location. Two of them were L21+ and the other two were L21-.
Here is a further breakdown by region.
NW France (N = 13)
L21+ = 8
L21- = 5
North Central France (N = 1)
L21+ = 0
L21- = 1
NE France (N = 4)
L21+ = 3
L21- = 1
SW France (N = 1; this one was close to Central France, near the Limousin
border)
L21+ = 1
L21- = 0
SE France (N = 1)
L21+ = 0
L21- = 1
Those are the results. Once again, I'm not claiming this was a truly scientific study. Our sample population was pretty obviously determined by North American immigration patterns (most of our test subjects are French Canadians). I don't think L21 is 60% of French R1b1b2 overall. I suspect it's more like 30-40%, but it could run as high as 50-60% in Northern France, especially Northwestern France.
Oh, one thing I forgot to mention in my earlier post: I purposely excluded men with ancestry in Bretagne (Brittany) from this recruitment/testing project. I have nothing against them; in fact, I hope they all test L21+ and join my project. I excluded them to avoid the claim that any of our test subjects was ultimately of British ancestry, which would have been the immediate objection to Breton results, regardless of any evidence to the contrary.
