Expert praise for Your DNA Guide—the Book:

[Diahan’s] friendly, familiar tone could convince anyone that they can figure out this whole “DNA thing,” and with Southard’s clear, step-by-step instructions, they can. – -Mary Kircher Roddy, FGS Magazine

“It’s definitely not a ‘big overview of DNA testing’ book, but instead a ‘let’s get down and dirty and solve a brickwall problem’ book. And we definitely need a book like this.” – Drew Smith, The Genealogy Guys Podcast and Genealogy Connection Podcast

“Diahan Southard is…funny and down to earth. Her presentations are always filled with color and graphics and explain the sometimes overwhelming topic in a simple and easy way to understand. She’s put her style into her first book on DNA.”

This book is unique. My first thought was this is just like the choose your own adventure books I used to read as a kid. It’s almost like having Diahan there to hold your hand while you work your way through your matches and find your family!” – Cheri Hudson Passey, Carolina Girl Genealogy

Your DNA Guide -- the Book

Stephen Snyder
A Guide that’s Kin to a Rand McNally Atlas

When traveling across country using roadways it’s helpful to have a reliable guide by one’s side. This DNA guide book with its ‘step by step’ plans is the one to have at arms reach on that journey. Although I have only begun to follow the route laid out by the author, if my path is carefully plotted in accord with steps provided, it would seem to be a given that I’ll attain my desired goal. This straitforward guide is written in a crisp stepwise fashion that provides both the needed background and insights to attain the desired goal. I am not a newbie to the research required to build a family tree or to using DNA connections in that regard. What I have not done to date is to use a systematic approach in determining how my DNA relatives relate to me and to one another. This guidebook, even for a grizzled user of some twenty-plus years, should prove very helpful in arriving at that ultimate destination. Better late than never!!

We're so glad you're enjoying the book - thanks for a great review!
