As Genetic Genealogist since 2004 I am thrilled to see the DNA research was up to the minute of publication. Mesolithic information has come out since then( December 2013) and shows my Faunt/L'enfant I2a1* Sardinian family right in the mix of it. The author, of course, would not have been privy to the prepublication data on the Mesolithic but she was exactly on target about their neolithic origins. Very exciting to me about this lineage is how accurately the DNA and the migration follows what we know from ancient paper records. This led me to go back and reread the parts about my other lines.
Jean Manco has a superb grasp on the anthropological and the genetic journeys of Europeans. I earnestly encourage other scholars, genealogists and scientists to obtain this book. It is worthwhile and priceless.
