I have spent most of my career surrounded by ghosts. Not the kind that rattle chains or flicker at the edge of sight, but the kind that linger in old photographs, in brittle letters, in the silent spaces between catalog entries. As chief archivist of the Baltimore Historical Society, I have handled thousands of images: the solemn faces of families, the rigid postures of men in starched collars, the unsmiling gaze of women in heavy dresses. I know the language of these artifacts, the way a hand resting on a lap can speak of comfort, or a sidelong glance can betray a secret. But nothing prepared me for the Montgomery photograph.

It was a Tuesday morning in March, the kind of day when the city’s gray light filters through the high windows of the archive room, settling on the stacks of boxes that fill every available surface. I had been working through the Montgomery collection for days—a donation from the estate of a once-prominent Baltimore family, untouched for decades. Most of the photographs were typical Victorian fare: stiff, formal, meticulously labeled, yet emotionally opaque. I was about to break for lunch when I unwrapped a particularly well-preserved portrait mounted on heavy cardboard.

The image was striking in its clarity. Two young women, perhaps in their early twenties, sat side by side in an ornate studio. They wore matching dark dresses with high collars and elaborate lace trim, their hair arranged in the fashion of the early 1890s. What caught my attention, though, was not their clothing or even their rare, almost defiant smiles, but the inscription on the back: “Caroline and Elizabeth Montgomery, Baltimore, October 1892.”

I positioned the photograph under my magnifying lamp, admiring the sharpness of the image. Every detail—the pattern of the wallpaper, the embroidery on the dresses—stood out in crisp relief. The sisters sat close, their shoulders nearly touching, radiating warmth and intimacy. And then my eyes drifted down to their hands.

Both women had their hands resting in their laps, but the positioning was… deliberate. Identical. Their thumbs extended, index and middle fingers slightly curved, the other fingers folded. Not a casual pose, not a standard Victorian convention. I’d cataloged enough photographs to know when something was off, and this was too intentional to be coincidence.

A tingle of curiosity ran down my spine. I photographed the image with my high-resolution camera, zooming in on the hands, and made a note to research Victorian hand gestures and photographic conventions. Something was hidden here, something that had gone unnoticed for over a century.

I spent my lunch break hunched over my laptop, searching digital databases of Victorian portraiture. Dozens of images flickered past, but none matched the hand position in the Montgomery photograph. Victorian photography had rules for everything—how to sit, where to look, what to hold—but this gesture was unique.

I decided to consult Dr. Patricia Chen, a colleague who specialized in 19th-century social history and non-verbal communication. I emailed her the high-resolution images of the hands, asking if she recognized the gesture or could provide context. She called within an hour, her voice urgent.

“Where did you find this photograph?” she demanded.

“In the Montgomery family collection. Why?”

“Do you recognize the hand position?”

There was a pause, then Patricia said quietly, “Rebecca, I think you’ve found something extraordinary. Can I come to your office? I need to see the original photograph.”

Forty minutes later, Patricia arrived, slightly out of breath from hurrying across town. I laid the photograph on my examination table, and she studied it intently, magnifying glass in hand. After a long moment, she looked up, her expression grave.

“I’ve only seen this gesture described in written accounts, never in a photograph. It’s a distress signal.”

My pulse quickened. “A distress signal?”

She nodded, pulling out her tablet and showing me a scanned page from a 19th-century women’s journal. “In the 1880s and 1890s, there were networks of women’s protection societies—secret organizations that helped women escape dangerous situations, forced marriages, domestic violence, trafficking. They developed coded signals women could use to indicate they were in danger, even in public settings where they were being watched.”

She pointed to a diagram in the journal showing a hand position nearly identical to the one in the Montgomery photograph. “This signal meant ‘help us’ or ‘we are in danger.’ It was subtle enough that men wouldn’t recognize it, but clear enough that women who knew the code would understand.”

I stared at the photograph with new eyes. The sisters’ smiles suddenly seemed forced, their expressions masks for fear. “They were calling for help,” I whispered.

“And someone might have heard them,” Patricia replied. “We need to find out what happened to these women after this photograph was taken. If they used this signal, they were in serious danger. The question is, did anyone save them?”

We spent the rest of the afternoon—and, truthfully, the next several days—reconstructing the Montgomery family history. City directories and census records painted a picture of a family in decline. James Montgomery, Caroline and Elizabeth’s father, had been a successful shipping merchant in the 1870s and early 1880s. But a hurricane in 1887 destroyed three of his vessels, and subsequent poor investments left the family deeply in debt. By 1890, they were facing the loss of their home and social standing.

Newspaper articles from 1891 documented James Montgomery’s business failures and the family’s withdrawal from society. Then, in September 1892, just one month before the photograph was taken, I found an announcement in the Baltimore Sun that made my blood run cold. “Mr. James Montgomery is pleased to announce the forthcoming marriages of his daughters, Miss Caroline Montgomery to Mr. Richard Thornton of Philadelphia and Miss Elizabeth Montgomery to Mr. Charles Hartwell of New York. The ceremonies will take place in November of this year.”

I dug deeper into the backgrounds of the prospective grooms. Richard Thornton was a wealthy industrialist aged 53—more than 30 years older than Caroline, with two deceased wives whose deaths were described as “sudden illness” or “tragic accident.” Charles Hartwell was in his early 40s, with a reputation for shady business dealings and, I discovered, a restraining order filed by a woman who claimed he had threatened her after she refused his advances.

Patricia, meanwhile, found something even more revealing: a diary entry from a Baltimore society matron, dated October 1892. “Saw poor Mrs. Montgomery at church today. She could barely meet my eyes. Everyone knows those marriages are business arrangements. James has sold his daughters to those dreadful men to settle his debts. The girls looked like ghosts at the autumn ball. Caroline actually flinched when Thornton touched her arm. It’s monstrous, but what can be done? The law gives fathers absolute authority over unmarried daughters.”

The pieces fell into place. The photograph had been taken in October 1892, just weeks before the scheduled weddings—likely commissioned by Thornton and Hartwell as a formal portrait of their future brides. Caroline and Elizabeth would have had no choice but to pose, to smile, to present themselves as willing participants in marriages they were being forced into. But they had found a way to resist, to signal their desperation.

I needed to learn more about the photograph itself—who had taken it, under what circumstances, and whether anyone present might have recognized the distress signal. The photographer’s mark, embossed on the bottom, read: “Sullivan and Daughters, Photography, Baltimore.” A search through city directories revealed that Sullivan and Daughters had been a prominent studio from 1885 to 1903, owned by Thomas Sullivan and his daughters, Margaret and Catherine.

I visited the studio’s former location on Charles Street—now a coffee shop, with apartments above. The manager, a history enthusiast himself, directed me to a small historical society dedicated to preserving Baltimore’s commercial history. There, I found archived business records from Sullivan and Daughters, including appointment books and correspondence. The appointment book for October 1892 showed an entry: “October 18th. Montgomery sisters formal portrait, 2 PM. Client: Mr. R. Thornton, prepaid.”

But it was a letter dated October 20th, 1892, that made my hands tremble. Addressed to a Mrs. Blackwell and written in a woman’s hand, it read:

Dear Mrs. Blackwell,

I am writing regarding a matter of utmost urgency. Two young women came to our studio yesterday for a portrait sitting. During the session, I observed them displaying the signal you taught me to recognize three years ago. They are in grave danger, scheduled to be married against their will next month to men of questionable character. Their names are Caroline and Elizabeth Montgomery. I have included their address and the names of the men they are being forced to marry. Please help them if you can. Time is short.

Yours in sisterhood, Margaret Sullivan

Patricia knew immediately who Mrs. Blackwell was. “Sarah Blackwell ran one of the most active women’s protection societies in Baltimore. It operated under the cover of a charitable ladies’ society, but its real purpose was helping women escape dangerous situations—forced marriages, abuse, trafficking. Most of its work was done in secret because what they did was often technically illegal.”

If Margaret Sullivan had contacted Sarah Blackwell, and if the Women’s Protection Society had intervened, perhaps Caroline and Elizabeth had been saved. But I needed proof.

Finding records of the Women’s Protection Society was not easy; organizations operating in legal gray areas rarely kept detailed records. But Patricia knew where to look. The Maryland Women’s Archive held a private collection of Sarah Blackwell’s personal papers—restricted, but accessible for research of historical importance.

It took three days to obtain permission. When we arrived, we were handed several boxes of Sarah Blackwell’s correspondence and journals from the 1890s. Her journals documented dozens of cases: women spirited away in the night, new identities created, transportation arranged to distant cities. And then I found the entry dated October 21st, 1892.

Received urgent letter from MS regarding two sisters in immediate danger. The Montgomery case investigated and confirmed—father has sold daughters to settle debts. Marriages scheduled for November 8th. Both men have troubling histories. MS reports sisters signaled distress during photograph session. We must act quickly.

Subsequent entries detailed the society’s plan. They had made contact with a housemaid in the Montgomery home who was sympathetic to the sisters’ plight. Through her, they sent coded messages to Caroline and Elizabeth, letting them know that help was coming and instructing them to be ready. The plan was risky: the sisters would attend a social function on November 6th, just two days before the scheduled weddings. During the event, they would excuse themselves to the ladies’ retiring room. Members of the Protection Society would be waiting with a carriage. The sisters would leave through a service entrance, and by the time their absence was noticed, they would be miles away.

Sarah’s journal entry for November 7th was brief, but triumphant. The Montgomery sisters are safe. They left Baltimore last night and are now traveling west under new names. Their father and the two men are furious, but there is nothing they can do. The law may give men power over women, but it cannot control women who refuse to be controlled. C and E are free.

I felt tears prick my eyes. The photograph that had captured Caroline and Elizabeth’s silent plea for help had worked. Someone had seen, someone had understood, and someone had acted.

But what had happened to the sisters after their escape? Had they truly been able to build new lives? Patricia found the next clue in Sarah Blackwell’s journals. The November 7th entry included more detail than I had initially noticed: The sisters departed on the 11 PM train to Pittsburgh, accompanied by Mrs. Henshaw and Miss Porter, who will escort them to their final destination. They travel under the names Sarah and Mary Thompson, sisters from Virginia, seeking teaching positions in California. Documents have been prepared supporting these identities. Their father has already been to the police, but we ensured no trail leads to our society or to the sisters’ actual whereabouts.

A December entry noted: Received telegram from Mrs. Henshaw. The Thompson sisters arrived safely in San Francisco. They have secured lodging and will begin seeking employment in the new year. Both are in good health and spirits, though naturally anxious about their new circumstances.

Throughout 1893, Sarah received occasional letters from Caroline and Elizabeth, written cautiously, never using real names or revealing too many details, but their gratitude and relief were evident. One letter from March 1893 read:

Dear Mrs. Blackwell,

We write to thank you once again for the gift of our freedom. We have found positions as school teachers in a small town near San Francisco. The work is rewarding, and we are building a life we could never have imagined in Baltimore. We share a small cottage, tend a garden, and each evening give thanks that we are here together and safe rather than trapped in the nightmare that was planned for us. The photograph that we risked everything to have taken—with our silent plea hidden in plain sight—saved our lives. Please convey our deepest gratitude to Miss Sullivan, whose recognition of our signal set everything in motion.

I traced the sisters’ lives through subsequent years, using the coded references in Sarah’s journals and by searching California records under their assumed names. Sarah and Mary Thompson, as Caroline and Elizabeth were now known, had indeed become teachers, working in a small school in San Rafael, just north of San Francisco. The 1900 census showed them living together, both listed as school teachers, unmarried. By 1910, they had opened their own small private school for girls.

An article from a San Rafael newspaper in 1905 praised the Thompson sisters’ excellent academy, where young ladies received not only academic instruction but also lessons in independence and self-reliance. Patricia found something particularly moving in a collection of letters from former students. One letter from 1908 mentioned, “Miss Sarah and Miss Mary always told us that education was the key to freedom, that with knowledge and skills, we could never be trapped or forced into lives we didn’t choose. They spoke with such conviction that I believe they must have learned this truth from personal experience.”

Caroline and Elizabeth had transformed their own escape into a mission to help other young women gain the independence and education that could protect them from similar fates. The school they founded wasn’t just about teaching reading and arithmetic—it was about empowering girls to control their own destinies.

While Caroline and Elizabeth built new lives in California, I wanted to understand what had happened to the men they had escaped and the father who had tried to sell them. The Baltimore newspapers from late 1892 and early 1893 told that part of the story.

The November 9th, 1892 edition of the Baltimore Sun carried a brief item: Social scandal rocks Baltimore—Montgomery Daughters Vanish on Eve of Weddings. The article described the sisters’ disappearance from a social function and noted that their father had filed a missing person’s report with the police. Richard Thornton and Charles Hartwell were quoted expressing shock and concern over the disappearance of their fiancées, but subsequent articles revealed that their concern was more about embarrassment and financial loss than genuine worry for the women’s well-being.

A November 15th article noted that Thornton was demanding James Montgomery repay money that had been advanced as part of the marriage arrangement. Legal proceedings were threatened. By December, the scandal had become more sordid. The Baltimore Evening News published an exposé revealing details about the arranged marriages, including the fact that Montgomery had essentially sold his daughters to settle his debts. Public opinion turned sharply against both the father and the would-be grooms.

A society columnist wrote scathingly, “Whatever one thinks of young ladies fleeing their family obligations, one must question the character of men who would enter into such mercenary arrangements. That Mr. Thornton and Mr. Hartwell sought to purchase brides rather than court them speaks ill of their qualities as gentlemen.”

The scandal intensified when a former housemaid in the Montgomery household gave an interview to a newspaper describing how distressed the sisters had been, how they had pleaded with their father not to force them into the marriages, and how their mother had wept but felt powerless to intervene.

Richard Thornton, facing social censure and business complications from the scandal, left Baltimore for Philadelphia, and largely withdrew from public life. I found his obituary from 1899. He had died at age 60, never remarried, his reputation permanently tarnished by the Montgomery affair.

Charles Hartwell fared even worse. The publicity surrounding the failed marriages prompted other women to come forward with allegations about his behavior. One woman filed a lawsuit claiming Hartwell had defrauded her in a business dealing. Another came forward with detailed accounts of his violent temper. By 1894, Hartwell had left New York and moved west, possibly trying to escape his reputation. I found a death notice from 1896 in a Nevada newspaper. Hartwell had died in a mining accident, though the circumstances were suspicious enough that local authorities had investigated whether it might have been suicide or even murder.

James Montgomery’s fate was perhaps the most pitiable. After the scandal and the loss of his daughters, his remaining business ventures collapsed. His wife Helen left him in 1893, moving to live with relatives in Virginia. James filed for bankruptcy in 1894. I found one final newspaper mention of him from 1898, a death notice indicating he had died alone in a boarding house, his remaining family estranged, his name synonymous with moral failure in Baltimore society.

The photograph that Caroline and Elizabeth had sat for, believing it might be their last hope, had not only saved them, but had also exposed and destroyed the men who had tried to control them.

As Patricia and I compiled our research into a comprehensive report, we discovered that Caroline and Elizabeth’s story was part of a larger pattern of women’s resistance to coercive marriages in the late 19th century. Sarah Blackwell’s journals documented dozens of similar cases—women who had found ways to signal distress, to reach out for help, to escape situations that the law and society said they had no right to refuse.

The distress signal that the Montgomery sisters had used in their photograph was just one of several coded communications that the Women’s Protection Society and similar organizations had developed. Patricia found a handbook from 1888, distributed secretly among women’s groups, that listed various signals: specific flower arrangements, certain phrases and letters, particular ways of wearing gloves or jewelry, and yes, hand positions in photographs.

The handbook explained, “In situations where a woman is being watched and controlled, where her words are monitored and her movements restricted, she must find ways to communicate that are invisible to her captors, but visible to those who can help. Learn these signals. Watch for them. A woman’s life may depend on your recognition and action.”

We decided to create an exhibition at the Baltimore Historical Society documenting not just the Montgomery sisters’ story, but the broader history of women’s resistance to forced marriages and the secret networks that helped them escape. The exhibition, titled “Hidden Signals: Women’s Resistance in Victorian America,” opened six months later. The centerpiece was the Montgomery photograph, displayed with detailed explanations of the hand signal and what it had meant. Visitors could read Caroline and Elizabeth’s letters, Sarah Blackwell’s journal entries, and Margaret Sullivan’s correspondence. Interactive displays allowed visitors to learn about other coded signals and the women who had used them.

The exhibition drew unexpected attention from modern advocacy groups working against forced marriage, which remains a problem even in the 21st century. Representatives from these organizations attended the opening, drawing explicit connections between the historical resistance networks and contemporary efforts to protect women and girls. One advocate spoke at the opening: “When I see this photograph, I see my clients—women who find creative ways to signal that they need help, even when they’re being watched. The methods have changed, but the need for vigilance, for recognition, for action, that hasn’t changed at all.”

The Baltimore Sun ran a feature article about the exhibition, bringing the Montgomery story to a wide audience. A descendant of Margaret Sullivan, the photographer who had recognized the distress signal, contacted me. The family had kept some of Margaret’s personal papers, including her diary from 1892. In that diary, Margaret had written extensively about the Montgomery photograph session. She described how nervous the sisters had seemed, how they had repeatedly positioned their hands in that specific way, and how she had recognized it immediately as the signal Sarah Blackwell had taught her years earlier during a Women’s Protection Society meeting.

Margaret had written, “I knew I had to act quickly but carefully. The men who commissioned the photograph were waiting in the reception area. I couldn’t let them see me notice anything unusual. So, I completed the session as if nothing was wrong. Developed the plates, delivered the finished photographs, but the moment they left, I wrote to Mrs. Blackwell. I only pray I acted in time to help those poor young women.”

My research into Caroline and Elizabeth’s later lives revealed that they had lived long, productive years in California, never returning to Baltimore or resuming their original identities. They ran their school for girls until 1920, when both retired in their late 40s. Census records and local documents showed them moving to a small farm outside San Rafael, where they lived quietly together for another two decades. They were known in their community as devoted sisters who had dedicated their lives to education and to each other.

I found obituaries for both women in the San Rafael newspaper. Elizabeth died first in 1939 at age 67, her death attributed to heart failure. The obituary described her as a beloved retired educator who, along with her sister, operated the Thompson Academy for many years, educating hundreds of young women and instilling in them the values of independence and self-reliance. Caroline died just 18 months later in 1941 at age 71. Her obituary was longer and more detailed, noting that Miss Caroline Thompson never fully recovered from the loss of her beloved sister, Elizabeth, with whom she shared a life of service to young women’s education. The sisters were inseparable in life, and it seemed fitting that they should be reunited so quickly in death. Both women were buried in the same cemetery, their gravestones simple but positioned side by side, still together as they had been throughout their lives. Neither had married, neither had children, but their school had educated more than 300 young women over its 25 years of operation. Many of those former students had gone on to become teachers, professionals, and advocates for women’s rights themselves.

Patricia discovered letters from former students in various California historical archives. Many wrote about how the Thompson sisters had changed their lives, giving them confidence and skills that allowed them to make independent choices about their futures. Several mentioned that the Thompson sisters always seemed to understand what it meant to have your life controlled by others, and they were determined that their students would never experience that.

One particularly moving letter from 1935, written by a former student who had become a social worker, read, “When I work with young women in difficult situations, I think of Miss Caroline and Miss Mary and how they believed that every woman deserved the chance to choose her own path. They never spoke directly about their pasts, but I always sensed that they had escaped something terrible and that their mission to help other young women was born from that experience. They saved my life by giving me an education and independence. I can only imagine how many other lives they saved over the years.”

I arranged for the historical society to place a memorial marker at the location of the old Sullivan and Daughters photography studio, commemorating both Margaret Sullivan’s recognition of the distress signal and the sisters whose courage in using it had saved their lives. The marker included a replica of the photograph and an explanation of the hidden signal.

The exhibition remained at the Baltimore Historical Society for a year and then toured other cities, reaching audiences across the country. Everywhere it went, visitors stood before the Montgomery photograph, studying the hands, understanding for the first time what had been hidden in plain sight for over a century. I gave numerous talks about the research, and at each one, people shared their own family stories: grandmothers who had fled forced marriages, great-aunts who had helped other women escape, coded letters and signals that families had preserved without fully understanding their significance.

One woman in her 80s approached me after a talk in Washington, DC. “My grandmother was rescued by Sarah Blackwell’s group in 1894,” she said quietly. “I always wondered how she had escaped. Now I understand that there were networks, signals, brave women helping other women. Thank you for bringing this history to light.”

The Maryland Women’s Archive, inspired by the attention the Montgomery case had received, launched a project to digitize and make accessible more records from women’s protection societies throughout the state. Researchers discovered dozens of similar cases—women whose distress had been signaled through coded messages, whose escapes had been orchestrated by secret networks, whose freedom had depended on other women recognizing and responding to their calls for help.

Patricia and I co-authored an academic article about the Montgomery sisters and the broader phenomenon of coded distress signals in Victorian America. The article was published in a leading history journal and sparked new research into women’s resistance strategies throughout the 19th century.

But for me, the most meaningful outcome was simply that Caroline and Elizabeth Montgomery’s story was now known. The photograph that they had risked everything to embed with their plea for help had finally delivered its full message more than 130 years after it was taken. The historical society kept the original photograph in its permanent collection, displayed prominently with the caption:

“Caroline and Elizabeth Montgomery, October 1892. This photograph shows two young women displaying a distress signal with their hands, calling for help to escape forced marriages. Their signal was recognized by photographer Margaret Sullivan, who contacted the Women’s Protection Society. The sisters were successfully rescued and lived free, productive lives under new identities in California. Their courage in finding a way to ask for help, and the courage of the women who answered that call, reminds us that resistance to injustice takes many forms, and that attentiveness to others’ suffering can save lives.”

Visitors often photographed the image, sharing it on social media with comments about the hidden signal and the bravery of the women involved. Several modern advocacy groups adopted the hand signal as a symbol of resistance to coercion and control, teaching it as a contemporary distress signal that could be used by women in dangerous situations.

Sometimes I stand quietly in the gallery, watching visitors discover the story. I see them lean in to examine the hands, see their expressions change as they understand what they are seeing, see them read the accompanying text with growing emotion. The photograph that had appeared to be simply a portrait of two sisters had become a window into a hidden history of courage, resistance, and the networks of women who had refused to let other women face danger alone.

The Montgomery sisters found a way to speak across more than a century. Their message finally heard and understood. Their hands, positioned so carefully in that Baltimore photography studio in October 1892, had reached across time to tell a story of terror faced, help sought, freedom gained, and lives reclaimed. And in telling their story, I have helped ensure that the countless other women who resisted, who signaled, who escaped, will not be forgotten either.

The photograph remains a testament to the power of small acts of courage and the importance of paying attention to what others might be trying to tell us—even when their voices are silenced and only their hands can speak.
