Discover the answers to your family history mysteries using the most-cutting edge tool available to genealogists. This plain-English guide, revised and expanded, is a one-stop resource on genetic genealogy for family historians. Inside, you'll learn what DNA tests are available, with up-to-date pros and cons of the major testing companies (including AncestryDNA) and advice on choosing the right test to answer your specific questions. For those who've already taken DNA tests, this guide will demystify and explain how to interpret DNA test results, including how to understand ethnicity estimates and haplogroup designations, navigate suggested cousin matches, and use third-party tools like GEDmatch to further analyze data.
Whether you’ve just heard of DNA testing or you've tested with multiple major companies, this guide will give you the tools you need to unpuzzle your DNA and discover what it can tell you about your family tree.
The first edition of this book came out in 2016, and as with most aspects of modern genealogy, the field of genetic genealogy changes quickly. In the few years since the first edition of 'The Family Tree Guide to DNA Testing and Genetic Genealogy' was published, new tests, new testing companies, new methodologies and new third-party tools have all been introduced. This book helps you navigate these latest developments while also covering shared matching, ethical questions about the use of DNA information by the government or other third parties, X-DNA advancements and much more!
