The Lost Family: How DNA Testing Is Upending Who We Are Kindle Edition

4.4 out of 5 stars 712 ratings

“A fascinating exploration of the mysteries ignited by DNA genealogy testing—from the intensely personal and concrete to the existential and unsolvable.” —Tana French, New York Times–bestselling author

You swab your cheek or spit in a vial, then send it away to a lab somewhere. Weeks later you get a report that might tell you where your ancestors came from or if you carry certain genetic risks. Or, the report could reveal a long-buried family secret that upends your entire sense of identity. Soon a lark becomes an obsession, a relentless drive to find answers to questions at the core of your being, like “Who am I?” and “Where did I come from?” Welcome to the age of home genetic testing.

In 
The Lost Family, journalist Libby Copeland investigates what happens when we embark on a vast social experiment with little understanding of the ramifications. She explores the culture of genealogy buffs, the science of DNA, and the business of companies like Ancestry and 23andMe, all while tracing the story of one woman, her unusual results, and a relentless methodical drive for answers that becomes a thoroughly modern genetic detective story. Gripping and masterfully told, The Lost Family is a spectacular book on a big, timely subject.

“An urgently necessary, powerful book that addresses one of the most complex social and bioethical issues of our time.” —Dani Shapiro, New York Times–bestselling author

“Before you spit in that vial, read this book.” —The New York Times Book Review

“Impeccably researched . . . up-to-the-minute science meets the philosophy of identity in a poignant, engaging debut.” —Kirkus Reviews (starred review)

Editorial Reviews

Review

“Before You Spit in That Vial, Read This Book.”―New York Times

“[
The Lost Family] wrestles with some of the biggest questions in life: Who are we? What is family? Are we defined by nature, nurture or both?”―The Washington Post

“A fascinating account of lives dramatically affected by genetic sleuthing.”―
The Wall Street Journal

“Copeland takes readers inside America’s first DNA testing lab dedicated to genealogy, to Salt Lake City’s Family History Library—the largest genealogical research facility in the world—and into the living rooms of dozens of people whose lives have been turned upside down due to the results of a recreational DNA test. It is at once a hard look at the forces behind a historical mass reckoning that is happening all across America, and an intimate portrait of the people living it.“―
Wired.com

“A fascinating deep dive into the massively popular world of direct-to-consumer DNA testing.”―
Associated Press

“Page-Turner.”―
Alison Stewart, WNYC’s All Of It

“Journalist Libby Copeland’s deep dive into the family secrets uncovered and privacy questions untested will blow your mind.”―
OZY.com

The Lost Family is a fascinating exploration of the mysteries ignited by DNA genealogy testing—from the intensely personal and concrete to the existential and unsolvable. In the world Copeland's 'seekers' are exploring, 'Who am I?' becomes a mystery more intricate and more crucial than any novel's 'Whodunit?' Copeland deftly weaves together individual stories, technical explanations and sociological discussion to make a book that's both gripping and deeply thought-provoking.”―Tana French, New York Times bestselling author of the Dublin Murder Squad series and The Witch Elm

“So many families have been touched—and will continue to be touched—by the secrets unearthed by home genetic testing. We are in an epidemic with few signposts, little to guide us as we contend with the unintended consequences brought upon us by scientific advancement.
The Lost Family is an urgently necessary, powerful book that addresses one of the most complex social and bioethical issues of our time.”―Dani Shapiro, New York Times bestselling author of Inheritance

"Not long ago, the idea of sequencing your DNA was as plausible as booking a trip to Jupiter. Now we give each other DNA tests as holiday gifts. As tens of millions of people look at their genes and link them to their ancestry, this science is having a profound impact on our society as a whole. It is reuniting relatives, breaking up families, and sending criminals to jail.
The Lost Family is a deeply reported, deeply humane exploration of our ongoing redefinition of our identity and our kinships."―Carl Zimmer, author of She Has Her Mother's Laugh: The Powers, Perversions, and Potential of Heredity

"A
compellingly readable narrative that takes us down the rabbit hole of modern personal genomics. Libby Copeland brings a gripping story from the front lines of genealogy and genomics."―Razib Khan, The Insitome Institute

“A riveting mystery combined with a beautiful meditation on family and identity. I read it in one sitting and immediately preordered copies for everyone I'm related to, both by blood and by love.”―
Monica Hesse, author of American Fire and Girl in the Blue Coat

“A fascinating account of consumer genetic testing’s ‘fundamental reshaping of the American family’ over the past two decades. … impeccably researched … up-to-the-minute science meets the philosophy of identity in a poignant, engaging debut.”―
Kirkus Reviews (starred review)

“…well-researched, thorough and fascinating
"The Columbus Dispatch

I can’t put it down.
The exquisitely detailed individual stories in this book are breathtaking, you do not have to “be into” genealogy or ancestry or dna-testing to get sucked in.

    I really enjoyed this book. Not only did I learn a lot more about DNA, but learned about the history of DNA testing for genealogy purposes. The book is very readable, however, so don't be scared away by the scientific aspects. I am looking for more books like this, as DNA testing continues to turn family history research on its head.
  • Reviewed in the United States on April 10, 2020
    Over the past ten years there have been enormous advances in the study of DNA and its concomitant application to genealogy, giving rise to “genetic genealogists.” Copeland’s work is an interesting, even intense, study of this phenomenon, combining the latest DNA science with individuals’ exploration of these latest advances. One family in particular is examined, but others are cited with reference to the variety of challenges facing the “seekers” as they are called. It is at once a fascinating detective story and a cautionary tale.

    It is cautionary in the sense that once someone spits in the vial of a company that sells home DNA analyses to the public, the results can be made public to an extent not suspected by the individual who embarked on what was touted as a fun experiment, say a search for ancestral origins. Occasionally, the outcome of the publication of the test is shocking, sometimes NPE, or not the parent/paternity expected, leading to finding new family, not always appreciated by those found. Unexpected links suddenly pop up. Donor-conceived individuals discover they have many more siblings than they even dreamed of, then start seeking their biological father. Adoptees discover for the first time that they are adopted; then begin a search for their biological parents. As the databases of the public DNA companies grow, results become more accurate – and the possibility of surprises pleasant and unpleasant increases.

    The companies that provide public DNA testing have a checkered history of providing privacy for their customers. DNA famously has been credited with identifying a serial killer and other criminals, as law enforcement authorities search public databases for family members linked to suspects. Less desirable is the thorny issue of the potential use of family DNA for health insurance companies to deny coverage for certain illnesses. Copeland notes these concerns, the need to balance the public good with private rights.

    Copeland touches carefully on the sensitive issue of race and racism. Race and culture are inflammatory subjects even for a journalist. She asks whether ethnicity is cultural heritage or genetic assessment.

    The “lost family” of the title is occasionally lost in some remarkably detailed and dense analysis of the science of DNA. The reader is rewarded for this slog through science when the family eventually re-surfaces and Copeland provides a satisfactory conclusion to their story. The basic theme of this book is that DNA analysis can be a useful tool for finding family, but one needs to be aware there is always some risk that you will in fact find unexpected family, and perhaps that the family does not want to be found. Spit with care.

    For anyone thinking of gifting a friend or family member a DNA test kit — add this book to the order so they know what they’re getting into.

    As a genealogist, this book is a must read — in fact, I’ve already sent it to several fellow genealogists. Whether we research for ourselves or others, as a hobby or a profession, we have been entrusted with the life and death details of real people. It can and should be done responsibly, humbly and with compassion — but what does that look like when secrets are uncovered?

    This book deeply, repeatedly and unflinchingly lays out the unintentional consequences that can and do come about when genetic genealogy is used to trace a family’s history through time.

    It also challenges us to think more intentionally about the meaning of family, of ancestry, of privacy and of identity. And it walks us through the ever-changing world of genetic genealogy — from the early days and early adopters to the current day and beyond.

    The Lost Family is a great read for anyone interested in family history, in the science of genetic genealogy or in the social constructs of race, ethnicity, family and self. It hits at the core of who we are — and what happens when everything we think we know about ourselves changes.

    Thought provoking.

    As someone who has not taken a test and never had the desire to, this was an interesting read. Touching on why it matters if I don't ever, but also how my choice may not matter at all.

    I enjoyed the scientific bits but found them to be shallow and disappointing, especially seeing as the science interrupted the stories being told. I found myself losing interest in the real life stories more and more as they seemed to drag on unnecessarily and the interruptions pushed my interest over the edge.

    Overall, I appreciate the questions asked, conversations started, and thoughtfulness put into this book.

    5.0 out of 5 stars Outstanding
    Reviewed in the United Kingdom on October 19, 2021
    This is a very thoughtfully researched book. It is NOT a how to guide to researching your family, it is not the place to look for support if you've had an unexpected DNA discovery or are embarking on the search as, for example, and adoptee aware of the missing pieces in their genetic origins. While there are some family stories woven into the document, they come alongside a very considered analysis of the ethics and consequences (expected and otherwise) of commercial DNA testing from a variety of perspectives. Truly thought provoking, one of the best pieces of work on the subject I've come across on this topic.

    THANK YOU
