On the seventh of September, 1973, a nineteen-year-old woman named Non Smith came home for lunch. She worked at a veterinary clinic in California, and she set down her purse and her keys in the apartment she shared with Brian Galvin. Brian was there. Police later believed he had been waiting inside.

He shot and killed her, and then he turned the gun on himself. Their bodies were found hours later, after Non failed to return to work. Brian was twenty-two. Non was nineteen.

Neither of them had lived long enough to be anything more than young people with plans. The news reached Colorado Springs and landed on a family that had no idea how to receive it. There had been no warning they had registered, no vocabulary for this kind of loss. Brian had been the fourth son, the one who was different in a way the family liked.

He was quiet where his older brothers were loud, handsome in a way that made people turn around, and he could play. He was a serious guitarist and a classically trained pianist, and by his late teens he was performing around Colorado with a band called Paxton’s Backstreet Carnival, playing lead guitar in front of crowds while his brothers were still figuring out what to do with themselves. To the younger children in the house, Brian was proof that a Galvin could get out. He wasn’t stuck on Hidden Valley Road.

He was on a stage. When he moved to California to chase it properly, playing sessions and working his way toward the record industry, the family was openly proud of him. Letters and phone calls came back with news of what he was doing. He was the good story in a house that had started running out of them.

What they did not know, or knew only in fragments because Brian kept the important things to himself, was that he had begun to slip in exactly the way his brothers Donald and Jim had. Friends noticed he had become withdrawn and suspicious. He had been put on medication for his mental health. He had been having a hard time, and none of it had been passed home in any detail.

On that September afternoon, the family had no warning that any of it was coming. To understand how the Galvins ended up at that moment, you have to go back to a photograph from 1961. It shows a family on the steps of a house in Colorado Springs: a father in Air Force uniform, a mother beside him, twelve children lined up by height. Within ten years, the oldest boy in that picture would be locked inside a state hospital.

Within twelve, another would be dead in California. The house at the end of the road sat on Hidden Valley Road, at the end of an unpaved stretch outside town, with space around it and mountains in every direction. It was isolated enough that a raised voice never traveled, and the road itself discouraged anyone from turning up unannounced. For a family that would soon have a great deal to keep private, the geography could not have been more convenient, though nobody chose it for that reason at the time.

Don Galvin and Mimi Blay met in New York in the early 1940s, when the war was swallowing up every young man they knew. She was a Manhattan girl with an appetite for opera and art and the kind of cultured life she assumed adulthood would hand her. He was charming, athletic, restless, headed for the Navy and then a long career in the Air Force. They married in 1944 in a hurry, the way a lot of couples married in 1944.

Their first son, Donald, arrived in 1945, and then the others came year after year with barely a pause between them. Jim in 1947, John in 1949, Brian in 1951, Michael in 1953, Richard in 1954, Joseph in 1956, Mark in 1957, Matthew in 1958, Peter in 1960. Then, after ten boys in a row, two daughters: Margaret in 1962 and Mary in 1965, the youngest of the entire family, who would later take the name Lindsay. Twelve children born across twenty years to the same two parents.

The Air Force moved them around, but they eventually settled in Colorado Springs, where Don worked at the Air Force Academy and later took a job promoting cooperation between the Rocky Mountain states. On paper, they were the postwar dream made flesh. Don was an officer with a talent for public speaking, the sort of man people wanted at their dinner table. He kept falcons, actual hunting birds, trained by hand, and he would take the boys out onto the open ground to fly them.

People would pull over on the roadside just to watch. Mimi ran the household with military efficiency, because there was no other way to run a household with twelve children in it. She painted. She loved the opera.

She had a fierce sense of how the family should look to the outside world, and she made sure it looked that way. The boys played hockey and football. They sang in the church choir, all of them in matching blazers. People in Colorado Springs genuinely talked about the Galvins the way you’d talk about a local institution.

There were so many of them that they were their own social world. They fought each other constantly, bloody, escalating brother-against-brother fights in the yard and the basement, but that was just what boys did. Nobody outside the house saw any of it anyway. For most of the 1950s and early 1960s, the surface was enough.

But somewhere underneath it, in the oldest boy, something was already beginning to come apart. If you had walked into that house in 1962 and asked which of the children was going to make the family proud, nobody would have hesitated. It was Donald. He was the firstborn, and he wore it like a uniform.

Tall, athletic, a football and wrestling standout in high school, good-looking in a way that made teachers, coaches, and parents all lean in the same direction. He was an altar boy. He dated a general’s daughter. He was the version of the family that Mimi wanted the world to see, and he played the part without ever seeming to strain at it.

But there were moments that didn’t fit, and the family filed them away without knowing what else to do with them. There was the day Donald walked into a bonfire, not near it, into it. He came out with burns and no explanation anyone could follow. There was a cat that ended up dead in circumstances the younger children only half understood and the adults preferred not to discuss.

At twelve years old, there were two separate occasions when he tried to end his own life, which the family absorbed and moved past because in 1957 there was simply no framework for what to do with a child like that. Each incident on its own could be explained away: a dare, an accident, a bad week. Together, they were a pattern nobody was equipped to read. Donald went off to Colorado State University in Fort Collins.

He studied. He joined things. He met a young woman named Jean and married her quickly, without much blessing from his parents. And it was there, away from Hidden Valley Road for the first time in his life, that the thing inside him stopped being a series of odd stories and became something that could not be hidden.

He began talking about religious visions. He told people he was a saint, not metaphorically and not as a joke, but as a fact he expected them to accept. He became convinced of things about his wife that weren’t true, and the marriage fell apart fast, ending after an incident in which he tried to seriously harm her. Jean left and never came back.

By 1970, Donald was back in Colorado Springs in his parents’ house, and he was not the same person who had left it. He wandered. He talked to people who weren’t in the room. He would appear in the kitchen wearing a bed sheet arranged like a robe, or nothing at all, moving through a house full of younger brothers and two little girls under the age of eight.

The word the doctors eventually used was schizophrenia. For Mimi, that word arrived with an accusation stapled to it. In 1970, American psychiatry had a favorite explanation for the illness, and the explanation was the mother. The theory held that cold, controlling, emotionally withholding mothers created schizophrenic children, that the illness was something a woman did to her son.

There was no evidence for it. It was assumed, repeated in textbooks, and delivered to women in hospital corridors as though it was settled science. So the first thing Mimi Galvin was told when her eldest son was diagnosed was that it was her fault. Donald’s hospitalization started and then simply never stopped.

The state hospital in Pueblo admitted him again and again over the following decades, more than a dozen separate times. He was medicated heavily, released, and readmitted. His delusions rearranged themselves over the years into stranger and stranger shapes. Decades later, in old age, he would explain calmly to people that he was the offspring of an octopus.

The family told itself this was a tragedy that had happened to one of them, a terrible piece of bad luck that had landed on the oldest boy. They believed that for about a year, until the brother who had spent his entire childhood competing with Donald began showing signs of the exact same thing. Jim was born two years after Donald, and he spent his whole life in the narrow, punishing space directly behind him. Everything Donald did, Jim did second.

Donald was the athlete, so Jim had to be an athlete. Donald was the favorite, so Jim was the one who pushed back. Their fights weren’t ordinary sibling scuffles. They were long-running, vicious, and frightening to watch, and the younger brothers learned early to get out of the room when the two oldest squared off.

In a house of twelve children, those two set the weather. Jim got out young. He married a woman named Kathy in his early twenties and started a family of his own, and for a short while it looked like he had escaped whatever had taken hold of his brother. He hadn’t.

Within a couple of years of Donald’s collapse, Jim was showing the same symptoms: the paranoia, the voices, the conviction that people were coordinating against him. He became the second Galvin son to be diagnosed. He was also, by every account from inside the family, frightening in a way Donald never was. He harmed himself when the paranoia got bad.

He turned on the people around him. There were episodes involving weapons in the family home, and at least one occasion where another brother, visiting with his own young children, realized what was happening and got them out. But the worst thing about Jim was something the family did not learn for years and would not fully confront for decades. Jim abused his two youngest sisters, Margaret and Mary, when they were small children.

It happened repeatedly over a period of years, in a house crowded and chaotic enough that two little girls could be harmed without anyone registering it. Both girls kept it to themselves. Margaret said nothing because she assumed it was her fault. Mary said nothing because she had already learned that the house had a strict, unspoken hierarchy of crisis, and two small girls were nowhere near the top of it.

When the truth finally came out in adulthood, it detonated in the middle of the family and raised a question nobody could answer cleanly: whether the illness had anything to do with it at all. The author who later spent years with this family was careful on exactly this point, and so is every clinician who has looked at it since. Schizophrenia does not cause someone to harm children. There is no evidence for that link, and the two things have to be held separately even when they occur in the same person.

Whatever drove Jim to do what he did came from somewhere else. There was a second layer underneath it. Years later, the oldest brother, Donald, disclosed that he had been abused as a boy by a priest who had made himself close to the Galvin family, a man who spent a great deal of time around a house full of young sons and who was later suspected of the same conduct elsewhere. When Mimi learned this, she seized on it as an explanation for the whole miserable chain: that a trusted man had worked his way into her family, picked out the son he wanted, and set something in motion that then moved from brother to brother.

Jim’s story ended on the second of March, 2001. He was found dead at fifty-three years old. The cause was tied to the enormous quantities of medication he had been taking for most of his adult life, the same medication that was supposed to be keeping him stable. But by the time of Jim’s death, the family had already lived through Brian’s single worst afternoon, and four more brothers were still to come.

Here is the part that is hardest to hold in your head. It didn’t stop. It kept going. The family would absorb a catastrophe, rearrange itself around the hole, get through a few years, and then another brother would start behaving strangely, and the whole thing would begin again from the top.

Joseph, born in 1956, was the quiet one, a strong hockey player who came out of high school with a steady future in front of him and took a job with an airline in Chicago. He had left Colorado. He was working, earning, independent. Then the voices arrived.

Joseph began seeing things in the sky, a figure he described as a Chinese emperor looking down at him and speaking to him directly. He acted on what he was told. He sent a threatening message to his employer, and the job was gone. And with it, the independence.

Joseph came back into the orbit of the family and into the same cycle of hospitals and medication as his brothers. He stayed gentle through most of it. The family tells a story about him quietly sending money to a niece so she could afford her college textbooks, five hundred dollars, from a man who had almost nothing himself. Joseph died at fifty-three, the same age Jim had been, and like Jim, his death was connected to the long-term effects of the drugs he had been prescribed for decades.

Matthew, born in 1958, was the artist. He worked in clay. He played the flute and the guitar, and he had an eye the rest of the family recognized as genuine talent. He also had a complicated history that makes his case unlike his brothers’.

As a child, a fight with one of his older brothers left him with an injury to his head, and in the mid-1970s he underwent surgery on his skull. His behavior changed noticeably afterward, and members of the family have always wondered how much of what followed traced back to that. His delusions took a strange and almost tender form. He became convinced he was Paul McCartney, not a fan and not an impersonator, but the actual man.

At other points he believed his own moods controlled the weather outside, which meant a bad day on his part was something he thought he owed the world an apology for. He cycled through hospitals and supported housing for decades, and in his best stretches he lived independently, made his art, and played his instruments. Peter, born in 1960, was the youngest boy, and the one it took hold of earliest. He was diagnosed at fourteen, younger than any of his brothers.

Before that, he had been the family’s prankster, the one who made the girls laugh and irritated his mother constantly. At fourteen, he was wetting the bed because he had become convinced there was something evil living underneath the house. Peter’s adult life became a loop of hospital admissions, escapes, medication changes, and returns. At one point he was being given six different antipsychotic drugs simultaneously.

And there was an afternoon Mimi never got past: arriving at a hospital in Colorado Springs to find her son strapped to a bed, soaked in his own urine. She took him out herself. For his siblings, Peter was the hardest one to reconcile because the person underneath the illness never fully disappeared. He remained a gifted musician, warm toward his brothers and sisters, openly affectionate in a way none of the others managed.

The family could sit with him on a good afternoon and recognize the boy they had grown up with, and then lose him again within a week. That was the treatment landscape those boys lived inside. Hospitals overwhelmed and understaffed. Drug regimens built by trial and error.

Insulin and shock treatments earlier on. Institutions that sometimes helped and sometimes simply held people. And underneath it all, a psychiatric consensus that kept circling back to the idea that a mother had caused this. Six sons, Donald, Jim, Brian, Joseph, Matthew, and Peter, diagnosed between the late 1960s and the early 1980s, in a family of twelve children in one house.

The four brothers who weren’t diagnosed had to build entire lives around the constant private arithmetic of wondering whether they were next. It’s worth stopping on Don and Mimi, because what happened to them is its own story. Don Galvin had built his life on competence. He was an officer.

He organized things. He flew falcons, gave speeches, moved his family across the country and set it down where he wanted it. Then one by one his sons began falling into something he could not organize, could not speak his way out of, and could not fix. He withdrew.

He worked more. He was away, or in his study, or out with the birds. Several of his children have described a father who quietly stepped back from the worst of it and left the day-to-day management of the crisis to his wife. By the mid-1980s, his own health gave way, a stroke that took most of his independence and left Mimi caring for him as well as for however many ill sons were in the house at the time.

He died in 2003, and several of his children have said he had been absent from the worst of it long before that. Mimi is the harder figure. For years she was, in the eyes of doctors and neighbors and eventually some of her own children, the explanation. The schizophrenogenic mother theory made her the cause.

She responded to that accusation the way she responded to everything: by refusing to yield an inch of ground in public and by keeping the household running. She cooked. She drove to Pueblo. She fought hospitals.

She took sons back into her home when there was nowhere else for them, sometimes several at once, into her seventies and beyond. She was also, in the eyes of her daughters, a woman who could not see what was happening to the children who weren’t sick, because every bit of her attention was consumed by the ones who were. There were things she should have noticed and didn’t. There were things she was told and did not act on.

Both of those descriptions are true at the same time. What almost nobody credits her for is the decision that outlasted her. Because at a moment when medicine had nothing to offer her family, Mimi Galvin made a choice that would end up mattering far beyond Colorado Springs. She said yes to the researchers.

And before that decision paid off, the two youngest members of the family, the only two girls, had to survive a childhood that neither of them has ever fully described as a childhood. Margaret and Mary were born into the tail end of it. By the time they were old enough to understand what a household was supposed to be, theirs was already a psychiatric ward with a kitchen. Mary, who would later go by Lindsay, was five years old when Donald came home from college transformed.

She has said plainly that she was too young to understand that her brother was ill, and that what she mostly felt was that she wanted this new frightening person to go away and her real brother to come back. That feeling, she has pointed out since, is one that siblings of people with schizophrenia know intimately and almost never say out loud. The girls grew up navigating a house where a grown man might be standing in the hallway at three in the morning talking to someone who wasn’t there. Where the police came and the ambulance came.

Where the rule was that you did not bring friends home, because you never knew what state the house would be in. And because Mimi’s absolute priority was that outsiders not see, they grew up carrying what Jim had done to them separately and in silence, each assuming she was the only one. Their escape came through a wealthy Denver couple, Sam and Nancy Gary, who had become close to the family and offered to take Margaret in. Margaret went.

She got a different house, a different school, a different life, and she spent years afterward weighed down by the fact that she’d been the one who got out while her younger sister stayed behind. Mary remained on Hidden Valley Road for longer, and their relationship carried the mark of that split for decades. Both girls got out eventually. Both built adult lives.

Both spent years in therapy taking apart what had been done to them and what they had witnessed. And both, at different points, made the decision that most people in their position never make: they went back. Mary Lindsay became the sibling who took responsibility. She managed her brothers’ care.

She managed her mother’s care in the end. She sat with the paperwork, the placements, the medication reviews, the phone calls. Margaret worked through her own reckoning with the family and eventually joined her in it. And it was the two of them who ultimately decided that this story should stop being a secret, which is what put a family from Colorado Springs at the center of one of the most important pieces of research in the history of psychiatry.

To understand why researchers wanted the Galvins so badly, you have to understand the problem they were up against. Schizophrenia is not rare. It affects roughly one in a hundred people worldwide. But it’s scattered, a person here and a person there, usually with no other case anywhere in the family.

If you’re trying to find a genetic signal, scattered cases are almost useless. You need concentration. You need a single family sharing an ancestry and an environment with enough affected members that the pattern can rise above the noise. Six brothers in one family of twelve was, as far as anyone could tell, unheard of.

The Galvins became one of the earliest families studied by the National Institute of Mental Health. Mimi handed over blood. So did the six sons. So did the well ones, and the daughters, and eventually the next generation.

Over years and then decades, that material was drawn, frozen, cataloged, and shared out to laboratories. Two researchers in particular built long careers around this family. Lynn DeLisi was a psychiatrist who had become convinced, against a fair amount of professional resistance, that schizophrenia had genetic roots and that families with multiple cases were the way to find them. She began collecting from the Galvins in the mid-1980s.

Her funding was not stable. At one point, a corporate takeover killed the program she was relying on, and the work stalled for years. She kept the samples. She kept going.

She later teamed up with a neurobiologist named Stefan McDonough, and in 2016 that collaboration reported a mutation on a gene called SHANK2 in the affected Galvin brothers, a gene involved in how brain cells communicate across the junctions between them. The mutation turned up in the ill sons and in their mother, and not in their father. Robert Freedman, working in Colorado, came at it from a completely different angle. He was interested in a specific quirk of the brain: the way a healthy brain filters repeated sounds.

Play someone two identical clicks in quick succession, and a typical brain will respond strongly to the first and much less to the second, because it has already decided the sound is nothing to worry about. Many people with schizophrenia don’t do that. Their brains respond to the second click as though it were brand new. The filter isn’t working, and everything comes in at full volume all the time.

Freedman traced that filtering failure through affected families and narrowed in on a gene called CHRNA7, which builds a receptor that the brain uses in that filtering process. Then came the part that turned a laboratory finding into something a person could actually use. Freedman worked out that babies born to parents with schizophrenia can already fail that filtering test within weeks of birth, meaning the vulnerability was being laid down before birth, not after. In the developing brain, those receptors rely on choline, an ordinary nutrient that comes from the mother’s diet.

Many pregnant women don’t get enough of it, which raised a genuinely startling possibility: that supplementing choline during pregnancy might help build that filtering system properly in children who would otherwise be at risk. The trial results have been encouraging. Choline has been pushed into prenatal nutrition guidance, and researchers have continued to build on it. None of this is a cure, and nobody involved claims it is.

Schizophrenia has since been connected to well over a hundred genetic variants, and it’s now generally understood as a developmental condition, something seeded early and triggered later, usually in late adolescence or early adulthood, by some combination of biology and circumstance. There is still no single gene, no switch, no simple answer. Mimi lived long enough to hear about the SHANK2 finding. She lived long enough to hear about the choline research, in her nineties, after a lifetime of being told that she had done this to her own children.

What she didn’t live to see was the moment her family’s name went everywhere. Don Galvin died in 2003. Mimi died in 2017 at the age of ninety-two, cared for in her final years by the youngest daughter. Jim died in 2001 at fifty-three.

Joseph died at fifty-three as well. Both deaths were tied to the long-term physical toll of decades of antipsychotic medication, and their mother was blunt about it afterward. She believed the treatment had killed them. Peter, the youngest brother and the earliest diagnosed, died in his sleep in October 2023.

His siblings held a memorial for him the following summer, and Donald, eighty years old by then, the first of them all to be diagnosed, was there. Donald and Matthew are the two who remain. Donald has lived for years in supported care in Colorado, quiet and reserved, still carrying delusions that have never left him, and by all accounts content with the shape of his days: a car ride, a meal from a familiar restaurant, an evening at the ballet or the opera or the symphony. Matthew moved into a skilled nursing facility in 2020 after long stretches of independent living.

He still plays music. His family still takes him on trips, and there are photographs of him out in the Colorado mountains with his brothers, looking exactly like a man on a good holiday. The four brothers who were never diagnosed, John, Michael, Richard, and Mark, built their own lives, their own marriages, their own families. Some stayed close to the rest.

Some kept a careful distance that has lasted decades. All of them spent their young adulthood watching for symptoms in themselves that never arrived, and watching their own children for the same thing. And then, in 2020, a journalist named Robert Kolker published a book about all of it. He had spent years with the surviving Galvins, with the medical records, with the researchers, with a family that had spent half a century being told to keep this quiet.

The book went to number one. It was chosen for a national book club. It became one of the most widely read pieces of nonfiction in years, and a documentary series followed. The reason it existed at all is that the two youngest siblings decided it should.

Margaret and Lindsay made the choice to hand over the story: the diagnosis, the hospitals, Brian, their own abuse, all of it, because they had concluded that the silence their mother had enforced for fifty years had protected nobody. Not the sick brothers, not the well ones, not the family’s reputation, which the neighbors had quietly worked out on their own anyway. They wanted other families to be able to say the word out loud. Go back to that photograph from 1961.

The father in uniform, the mother with her hands folded, the ten boys and the baby girl, the mountains behind the house. Everything that would happen to those children over the next sixty years was already present in that picture, coded into them, waiting for the years when it would begin to express itself. Nobody looking at them could have seen it. There was no test that could have found it.

And the science that might one day let a family like that catch it early came, in large part, from the blood of the very children standing on those steps.
