[13 Aug 2021] This really is a well written, easy to read and highly informative account of the uses of DNA testing in Family history. It is simple, logical and easy to understand. Difficult scientific concepts are well described and explained and really helpful in allowing family historians to understand how they might help their research. I enjoyed reading it, but there are inconsistencies, the first part which focuses on DNA, is I think better written and more authoritative than the second part about Networking which is more 'chatty' in style. The important thing to remember is at the time of writing (2011) the science of DNA testing to determine ancestry and origins was really in its infancy and the application of these techniques had not-been fully explored. I am aware that there have been significant developments in the field, so it is hard to judge if the book has gaps on the basis that it is now clearly out of date.
The second part about Networking was less than balanced and although we all know that some social networking sites have advantages, we now know that there are significant risks for the unwary. Some of the sites discussed no longer exist. I enjoyed this book and if nothing else it does offer a good early grounding on which to base further reading, but much of its content has been superseded by scientific, family history and other social developments. The book is good, but now regrettably extremely out-of-date.
