At-home DNA testing is all the rage these days. How much percentage British are you? Where did your ancestors come from? To whom are you related? So many of us want to spit in that tube and then peer at the pie chart that comes out of it, but the results can be far more complicated than that. I’m one of the millions of Americans who spit in the tube and clicked the link that wound up in my inbox several weeks later, informing me that I’m a good 30% Norwegian, but almost not at all Italian, despite my mother’s Italian maiden name. Fascinating! And that’s why The Lost Family: How DNA Testing is Uncovering Secrets, Reuniting Relatives, and Upending Who We Are by Libby Copeland (Abrams Press, 2020) appealed to me so much.
The Lost Family starts out following the family of Jim Collins, the Irish Catholic patriarch who had grown up in an orphanage, and who always struggled with his fractured family. Technology hadn’t advanced far enough at the point of his death, but afterwards, when home DNA testing was in its early days, his daughters began uncovering some shocking mysteries. Why weren’t they Irish at all? How on earth were the tests saying Jewish??? Why was Dad (Jim) so very short? What was going on?
Interwoven between the stories of the Collins family and other families whose DNA tests came up with surprises or mysteries are in-depth looks at how the ancestry and at-home DNA testing industry runs: how it began, what it means to the people who ran it (most of them genuinely seem like good people and are super enthusiastic about genealogy), and what the implications are, legally and morally, both for now and in the future. If you’ve ever taken one of these tests or you’re thinking about it, or you just want to put together a family tree, this is a book you need to pick up!
Phew. There is a LOT of information in this book. I was expecting it to be a little bit more about stories like the Collins’ family (and they’re definitely in there; their story and others like theirs are just scattered in between more broad information about companies like Ancestry.com and 23andMe), but I walked away with far more knowledge about the genetic testing industry as a whole than I expected. A lot of it was beyond me; I couldn’t begin to explain to you how any of the genetic comparison works and how to distinguish a third cousin from a great-uncle, genetically speaking, but there are plenty of people who could, and they’re REALLY into it (I envy their ability to grasp that kind of stuff. My brain just doesn’t work that way). I did like learning about how the companies grew and how they’re dealing with the more ethical concerns (how to aid customers who are shocked by their results; how to deal when the FBI comes calling and wants to compare genetic data on file with what they have from a crime scene or two), but what I really enjoyed were the personal stories, the family searches and bewilderment, the joy in discovering new relatives, the pain at losing what they thought was family-by-blood, or being rejected by newly discovered blood relatives. Those were the stories I enjoyed most about this book.
This was a slow read for me, simply because the book was densely packed with info, but it’s great science writing with a personal touch. I enjoyed settling down to read this book.
