There is no doubt that DNA and genealogy go hand in hand, but where do you start? What is the difference between the tests? What company is best to use? How do I interpret my results? My relatives won't test, what do I do? These are just some of the many questions that get asked by those new to DNA.
DNA testing can provide evidence of relationship even when no documents exist, and it can help you find family that you never knew you had.
It will not replace the more traditional genealogical research techniques - the paper-trail and gathering oral and documentary evidence and compiling family trees is still a valid and needed part of family history research. Instead it offers entirely new research tools, as well as a way of testing to see if the conclusions you have drawn are confirmed by this new evidence.
This book shows you how you can use DNA to harness this exciting new range of genealogical tools.
DNA tends to have its own language which can be rather intimidating, however this publication provides a glossary for easy reference and understanding, as well as details of all the testing companies, the places you can upload your DNA results to, and other tools useful for those doing genetic genealogy.
Now into its fourth edition, this book has been revised and updated to include the latest updates for genetic genealogists.
