Hello Maciamo,
How can U106 be that high in Luxembourg (near the level of Netherlands)? Did the Franks settled in great number in Luxembourg and replaced the celtic tribe ? or just ruled the already present population ?
Maybe we need to wait for more samples before drawing conclusion (like the undersampled 40% of U106 in the province of Luxembourg in Wallonia).
By the way, thank you for your work.
Luxembourgers speak a Frankish dialect, so it is undeniable that the Franks settled there in number high enough to become linguistically dominant over Latin speakers.
