What’s the book about?

It’s about what happens when individuals discover that the families in which they were raised are not entirely—or not at all—their biological families. In Relative Strangers: Inheritance, Identity, and the Meaning of Kinship, 28 acclaimed and emerging writers explore their life-changing discoveries of unknown close family—blindsiding revelations that can shift or fracture identity and lead to a redefinition of family. It shines a light on the experiences of those who live in the aftermath of encountering unknown parents and siblings and cope with the fallout: identity disruption, family dysfunction, the longing for biological kin, the messy complexities of reunion, the sting of rejection, and the joy of connection. Woven through is a universal question: What does it mean to be family?

Why Now?

Almost everyone knows someone who’s purchased a $99 DNA test to find out more about their genealogy, spit in a tube, and learned something entirely unexpected. The discovery of unknown family resulting from the exposure of family secrets—including those related to adoption, donor conception, and extramarital affairs—is far from a rare occurrence. Millions of Americans are making mind-blowing and profoundly consequential discoveries as a result of DNA testing. As of 2025, more than 40 million people have taken a direct-to-consumer DNA test, and research suggests that one in four of them have discovered previously unknown close relatives. Further, it’s been estimated that 1% to 5% of all who test—or between nearly half a million and 2 million individuals—discover an unexpected parent. Given the phenomenal popularity of DNA testing and its evergreen appeal, it’s clear that the extraordinary number of people experiencing DNA surprises will continue to rise significantly, meaning the essays in this anthology will be pertinent to a wide and growing swath of the population—and for a very long time.

Why it Matters

Finding out that a person one believed to be one’s parent or sibling is not genetically related can be devastating and destabilizing, as can discovering that a perfect stranger is your biological parent or sibling. These revelations trigger a cascade of emotions, including anger, shame, confusion, and—when that knowledge was known and kept from a person—betrayal. Those who make these often shocking discoveries frequently experience anxiety, depression, and panic disorder; some are traumatized by the experience. Similarly, being the ones on the other side of the door—the ones discovered out of the blue—can be equally blindsiding and may cause shame, family chaos, and anger that what they believed to be their right to privacy has been compromised. By telling their stories, the essayists in this anthology are helping others feel seen and validated and are healing themselves by reclaiming and sharing their truth. At the same time, they’re creating awareness and encouraging empathy and compassion in those who’ve never had these experiences, so that perhaps when new relatives reach out to relative strangers, they’ll be welcomed.

The End of Anonymity

DNA testing is bringing secrets to light, making anonymity with respect to parentage no longer guaranteed. Simply spitting in a tube and sending it off to a lab can cause secrets kept over decades to unravel in an instant. At the same time, advocates for donor conceived people are chipping away at anonymous donation, while adoptees are fighting for their right to their original birth certificates and access to their files. People who have genetic privilege—the knowledge about their origins—may not understand the consequences of the lack of such fundamental information or the importance of making anonymity a relic of a time gone by. Genetic identity is a birthright; we all have the right to know who we are and who and where we come from.

The Stakes are High

These shocking revelations can have deeply disturbing repercussions for all involved, including emotional overwhelm, family turmoil, shattered relationships, grief, and identity disruption. Worse, wanting to know where one comes from isn’t just a matter of filling in a puzzle piece and wrestling with difficult emotions: It’s also sometimes a matter of life or death. For adoptees and NPEs, having unknown parents also means having incomplete medical histories, which can be critical for people with heritable conditions including cancers, cardiac conditions, and more. Sixty-four percent of people who’ve uncovered misattributed parentage have learned that their medical histories and health risks have changed. In closed adoptions, in donor conception with an anonymous donor, and in NPE situations, not having access to medical information prevents individuals from making informed decisions about their health and from getting appropriate early screening, preventive care, and treatment. In the interest of keeping secrets, lives may be lost.

Secret-keeping and Shame

People who discover misattributed parentage are often stigmatized, shamed, and made to feel responsible for the manner of their conception. They may be labeled “illegitimate”—an archaic, hurtful, and invalidating term that’s damaging to self-esteem and contributes to shame. Parents who kept the truth from their children to protect themselves from judgment often pressure their children to keep the secret of their origins, thus transferring to them their shame—a burden that isn’t their children’s to carry. Not only is there a steep emotional cost to shame that’s paid by the children of the secret-keepers, but there’s also considerable research indicating that secret keeping is deleterious to physical and mental health.

Identity Disruption

Identity disruption leaves individuals feeling untethered to reality, questioning everything they thought they knew about themselves. The origin stories they believed were theirs are no longer pertinent to their lives and the stories they’ve told themselves about who they are have shattered. The composition of their families has rearranged itself; their race, religion, and ethnicity may have changed. It’s a complete shift in their basic sense of self—a crisis of perception that can give rise to mental health issues and even trauma.

Family Disruption

The revelation of DNA surprises can bring families closer together or tear them apart. The pressure to keep secrets and the unwillingness of some family members to acknowledge the truth can strain and even shatter relationships. Some who discover secrets about their origins are even cast out of the families in which they were raised, simply for wanting to know or share their truth.

Genealogical Bewilderment

In 1965, psychologist H.J. Sants coined the term genealogical bewilderment to describe the experience of loss, confusion, grief, anxiety, and identity disruption that results from having been separated from biological family. The lack of knowledge leads to an ongoing yearning to find one’s biological family. But that need to know—to search and seek family—is widely misunderstood by those who’ve never experienced it.

Search and Reunion: A Blessing or a Curse

It’s complicated … and messy. These discoveries can lead to loving reunions and the forging of deep new family ties when the seekers are welcomed, and the new relationships with biological family can help heal and restore identity. But reunions aren’t always joyful. And while they sometimes lead to the creation of deep enduring bonds, even when positive and desirable they can be difficult to sustain. And when individuals reach out to newly discovered family members, they’re sometimes not welcomed, or even acknowledged. Rejection adds a new level of heartbreak. These new relationships are complex and difficult to navigate, and even when they are joyful can be challenging.

Rejection

Perhaps the most damaging aspect of the discovery of surprise family is rejection, and it can come from all directions. Those who reach out to newly discovered family may be ignored. Doors won’t open and messages won’t be returned. Or they’re met with cruel and outright rejection, asked to “cease and desist” all effort at contact. And sometimes, the newly discovered relatives are eager for contact but the people who’ve made the discoveries are unwilling to connect. Remarkably, families of origin—parents and siblings with whom individuals were raised—sometimes reject those who reveal their discoveries, essentially casting them out of the family.

Joyful Connections and Validation

Although individuals’ origin stories and families can be upended by the revelation of secrets and the discovery of unknown relatives, families are often enlarged when everyone on all sides of the discovery are welcoming and open to redefining family and developing relationships. Deep and lasting bonds are formed, and connection with biological family can let individuals feel for the first time that they belong somewhere—that they fit; they see themselves reflected in others. And while surprise discoveries can cause emotional turmoil and identity disruption, they also can lead to a greater self-understanding and a sense of wholeness, providing validation for those who always sensed that something was amiss.

The Universal Question: What Does it Mean to Be Family?

Does shared DNA make us kin? How does it change us to learn that our family ties are not what we believed? What do we owe to the people whose DNA we share, and how do these discoveries affect our relationships to the families we’ve known—with whom we now share no DNA?

Grief – Disenfranchised Grief and Ambiguous Loss and Grief

Virtually all discoveries, whether the experiences are painful or joyful, involve grief. There’s grief, for example, when one learns that one’s biological parent is deceased or when the possibility of connection is blocked by rejection. After reunions, there can be grief for all the years the seekers didn’t get to be in the presence of their new family members, and there’s grief about the what ifs and the lives that might have been. This is disenfranchised grief and ambiguous loss—loss that’s not acknowledged or legitimized by society or by loved ones and for which there’s little understanding.

The Importance of Storytelling and Truth Telling

People who’ve made surprising family discoveries are often asked to carry their truth silently—to keep secrets—and by doing so, they lose their voice. Speaking out about these experiences in conversation and on the page—though exceedingly difficult—is a way to reclaim one’s truth at the same time that it validates another’s.

Mental Health Needs

Research has shown that individuals who face these complex consequences of the discovery of unknown relatives are more likely than others to experience anxiety, depression, and panic disorder. Many are traumatized by the experience. Roughly one-third of those who’ve learned about misattributed parentage have reached out to mental health professionals to help cope with the discovery and its challenges and emotional consequences. And while certain individuals, advocacy groups, and organizations are working hard to turn the tide through education, the fact is that most therapists and social workers are not adequately trained to cope with identity disruption and the fallout of DNA surprises.
