Evidence for dynastic succession among early Celtic elites

I do not know if the PCA includes all the IA Alsatian samples available, but 40 AI1 genomes from Duttlmenheim should be published, the sonner the better. ]

Great news.

At the same time, I'd be tempted to say : Alsace again ! 

It's a bit of a pity that, though more and more ancient samples are published, the central areas of France, from Toulouse to Orléans, from La Rochelle to Lyon, remain a "genetic void". I wish they'd analyze a few Ruteni, Arverni, Bituriges or Carnutes...

Also the yDNA haplogroups assignment would be great, since its one of the largest Hallstatt samples and might be more representative for Western Hallstatt than earlier ones.

I just analysed the one which is I-L38 according to theytree (https://www.theytree.com/portal/index/sa...eyword=mbg) and it is indeed I-L38

seven SNPs of block I-L38 derived and one SNP of block I-L38 ancestral.

The Lech Valley Early Bronze Age samples are entirely contained within the area occupied by the new SW German Hallstatt Celtic samples. Which means these Hallstatt people were similar to their Bronze Age predecessors 

Do the Lech valley EBA samples overlap with any BA samples from France?

The Hauts-de-France sample in green is the Bucy-le-long sample (BFM265). He lies at the fringe of the German samples. We should bear in mind that the Hallstattian zone of influence  in France never really concerned the Hauts-de-France, which seems to have had its own specific history.

Right. But the bulk of the Hauts de France blob on your PCA overlaps with the Hallstatt german samples, so couldn't that guy be more a "British/Armorican local like" outlier? Apparently RSFO migrants/ceramics from the south did reach to parts of Hauts de France, especially the south eastern half.
