I love the book, but am still stuck on finding matching DNA for my childrens’ great grandfather whose parents were killed in a fire and he and his two sisters put in an orphanage and he was adopted.

My reaction to the book was, "Wow! I didn't realize DNA was such a confusing subject."

Very Helpful Guide

I like the book so much that I gave it away, then had to buy another so that I could do the Ancestry course.
I'm still unclear on how to interpret X-chromosome matches. Maybe reading that chapter a few more times will help.

Wow! I bet whoever your shared your book with is very grateful to have a friend like you! XDNA can b tricky to work through, we have a few XDNA tips on our webiste as well:

I love this book. It allows you to get right into your particular DNA challenge and learn what you need to know, as you need it. Plus, it has a very refreshing, accessible, and inviting style.
