Family History in the Genes is an easy to read and understand explanation of how DNA is used. The only misunderstanding I had was that it is published by The National Archives - The BRITISH National Archives, not America's! It wasn't much of a problem, except all the examples and websites referred to were British. Also, this book was published in 2007, so I'm curious to know what updates have been made in the field since then.
Quite an interesting read but didn't really learn a lot from it :( However, there were one or two Golden Nuggets of info such as the mention of the "GOONS" website - Guild Of One Name-Studies - soooo important!
