My DNA Testing Guide

If any of the following apply to you, this DNA Testing Guide is an essential resource.

  • Are you a genealogist with brick walls in your family tree? An adoptee searching for your first family?
  • Do you want to know if two people are related and how? Would you like a breakout of your ethnic ancestry?
  • Even if you're just curious about the new world of genetic genealogy, you need my Guide to DNA Testing.

A Plain-English Overview for Adoptees, Genealogists, and Everyone Else

I tell you what DNA testing can do for you. Then I describe and compare the major genetic genealogy tests. I summarize their purposes, strengths and limitations. Then I provide links to educational resources and amazing third-party tools that can save you hours of time researching your ancestors. After reading this overview, you will be able to make test decisions with confidence.

Why No Print Version?

I only offer the Guide as an eBook for two reasons. First, the field of DNA testing changes so rapidly that I need to periodically update the information. That is not practical for a printed book.

Secondly, much of the practical value of this such a book lies in the dozens of links to recommended DNA tests, books, and third party resources. In my eBook you simply click to go there. In a printed book you would have to type a long URL for every place you wanted to check.
