List,

The following article is being discussed in other venues and the "full
article" is available in pdf here:
http://www.sciencedirect.com/science?_ob=MImg&_imagekey=B8JHP-4XH56GG-1-3&_cdi=43704&_user=10&_pii=S1875176809002340&_orig=browse&_coverDate=12%2F31%2F2009&_sk=999979998&view=c&wchp=dGLzVzz-zSkWA&md5=624f7cceca7d3cab2a62eebef75b5a66&ie=/sdarticle.pdf

This paper by Ramos-Luis et al., 2009 explores the haplotype and haplogroup
structure of seven regions in France. Alas they employed samples from the
largest cities in these areas (reflecting how the Forensic and Genetic
Genealogy communities often do not see things from the same vantagepoint).
The sample size of 555 is fine. Unfortunately there is no raw data or
summary data at all (that I could locate). So there does not seem to be any
way to obtain this information other than contacting the lead researcher.
They only note, almost in passing, that the most frequent variety of R1b1b2
was R1b1b2* (L21?) in all regions except Alsace where R1b1b2h (R-U152) was
the most common variety. Furthermore it was only in Midi-Pyrenees where
R1b1b2e was found. Surely they mean R1b1b2f (SRY2627) rather than R1b1b2e
which is M222 (Ui Neill, and a sub variety of L21).

I am not sure if this is a prelude to a more extensive analysis of the data
since the two pages and a couple of references provides only spotty and not
terribly useful info. They do have a scaling plot showing how Brittany is
an outlier to the rest - but that is it for the figures and tables.
