If you have already read Brian Sykes' "The Seven Daughters of Eve", you will be familiar with a number of the arguments raised in this book. In the "Seven Daughters" , Sykes explored the theme that most people of European origin are descended from seven clan mothers at varying times in the past 40,000 years. Interestingly as an aside in the current work, he makes the point that he now believes an Eighth daughter should be added.The current book extends this argument, to consider the genetic origins of the "tribes" of the British Isles. If you have not read the Seven Daughters, the first chapters provide a useful background to Sykes research methods and how these developed- if you have read the previous books this can be a bit repetetive, although in fairness he does try and keep this to the minimum required for the first time reader. The first chapters also provide a useful potted history of the Isles from the re-population after the Younger Dryas event at the end of the last Ice Age.
The second part of the book, considers the individual origins of the Irish, Scots, Welsh and English, based on Sykes analysis of Mitochondrial DNA and the Y Chromosone. I found the chapters relating to Ireland and Scotland more interesting- perhaps because the genetic patterns are more distinct, enabling Sykes to draw some firmer conclusions. The chapters on England, seemed weaker - probably this is no fault of the author's- the differences between Frisian, Saxon and Norman DNA, does not seem great enough to allow any firm conclusion on this. In any case, the book goes some way to demolishing the myths of the Saxon origins of the English and an ethnic cleansing of the Celtic population, genetically most of us remain pretty Celtic.
It is difficult, to pitch this type of book between loading on the statistics and baffling the general reader- possibly it leans a bit too far to the general reader, I was left looking for a bit more detail in places. Nevertheless, the writing style is engaging throughout, and the book contains enough nuggets of interest to make it worth the purchase. I would well recoomend to readers with a general interest in the history of the British Isles and for the those with an interest in their distant Brritish family history.
