L51* seems pretty common in the Romance substrate area given its normally low presence anywhere. It continues the impression that L51* correlates well with the Celto-Italic world (and beaker distribution) as indicated on RR's map. It also seems to confirm L51*'s relative absence in the modern Slavic and much of the north Germanic area. L51* did have a little patch on RR's map around the Upper Elbe but not anywhere else in northern Europe east of the Rhine. It does seem to confirm that the overall presence of L51* does correlate with the beaker network prior to its later extension into northern Europe. The question of direction remains open but L51* is a son of L23* and that is much higher in the southern and south-central part of Europe. It doesnt make anything conclusive but it has incrementally move us forward in our understanding.
Of course before the last map of Richard Rocca there has been another by Argiedude and me, and these data from the Rhaetian Region confirm all my theories.
R-L51 in the Romance Region of East Tyrol is at 14,28% and in the total Region at
4,81%. It's origin from R-L23/L150+ (which is also my haplogroup) confirms the origin in Italy and its first expansion to Iberia (presence of R-L51 in Valencia Region and Central Portugal where agriculturalists from Italy landed), then Beall Beakers (speaking a Celtic language derived from Ligurian) to Central Europe and the Isles. All clear for me. And for you?
