Dienekes has a post on a new study on French mtDNA. I agree with Dienekes that a large scale study on French genetic diversity has been a long time coming. This one has a good diverse sample size: 868 people from 12 regions. I don't have access to the full text, but it looks like they also further compare the Basques and the Britons (1/4 of my ancestry is Breton, partly explaining my first name). They don't seem to find anything too surprising, except maybe for: "the French Basques exhibit a number of distinct features, most notably expressed in the prevalence of haplogroups linked with the Neolithic diffusion in Europe", which is somewhat expected, but good to further confirm.
