In September 2019, a water-stained cardboard box arrived at the Atlanta History Center as part of the estate of Dorothy Williams, who had died at 97. Among the family belongings sat a photograph with curled brown edges, showing three Black women posed formally in a studio setting. The photographer’s stamp read “J. B.
Tinn, Atlanta, Georgia, 1899. ”
Intern Marcus Thompson, who had spent two years studying post-Civil War African American history, began cataloging the box as routine work. At first, the portrait looked like countless others from the era, with the subjects wearing their finest dark dresses and serious expressions common to long exposure times. Then Marcus noticed the hands.
The three women had positioned their fingers in deliberate, unusual configurations. The mother’s right hand rested on the chair arm with her thumb, index, and middle fingers extended while her ring and little fingers curled inward. The daughter on the left held both hands at waist level with palms facing each other but not touching, fingers spaced in a careful pattern. The other daughter placed one hand near her collar with fingers arranged in a precise formation.
Marcus photographed the image and enlarged it on his phone. The positioning was too intentional to be accidental. After four hours of comparing the hand positions with historical references, Marcus called Dr. Patricia Hayes, the center’s senior historian.
“Dr. Hayes, I think I found something important,” he said. She arrived within twenty minutes. When she studied the hands and then compared the image with photographs on her own phone, she asked Marcus if he knew what the Underground Railroad was.
He gave the common answer: the network that helped enslaved people escape to freedom before the Civil War. “Before and after,” she corrected. Most people believed the Underground Railroad ended in 1865 with emancipation and the Thirteenth Amendment, but violence had not stopped. Lynching, forced labor contracts, and discriminatory laws created new ways to legally oppress Black people, and some secret networks continued operating to help families escape to safer areas.
Dr. Hayes showed Marcus scanned pages of historical documents containing crude drawings of hand signals used by network conductors to recognize each other and share information, signals that had rarely been photographed and were passed down through oral tradition. Dr. Hayes contacted Dr.
Leonard Washington, a Howard University historian who had spent fifteen years researching encrypted communication systems used by formerly enslaved people. He arrived in Atlanta two days later carrying documents, memoirs, and testimonies collected from descendants of Underground Railroad participants. Examining the photograph closely, Dr. Washington identified the mother’s hand signal as a “safe house sign,” indicating a location where people could find shelter, with the specific finger configuration communicating how many days someone could stay safely.
The daughter on the left showed a distance marker, with the space between her palms representing roughly twenty meters to the next safe point. The daughter on the right displayed the most critical signal: a warning sign near her throat, with two fingers raised indicating the type of danger, in this case law enforcement or bounty hunters. “These three women are communicating,” Dr. Hayes said.
“A safe house is available, the next point is twenty miles away, and beware of law enforcement. They encoded an entire message inside a family photograph. ”
Dr. Washington noted that the photographer, J.
Tinn, had appeared in testimonies as a sympathetic figure who created convincing photographs, sometimes including people who were not actually present, producing documents for those who needed new identities. The photograph had been taken thirty-four years after slavery officially ended, raising the question of why such signals were needed in 1899. Washington explained that 1899 was one of the worst years for racial violence in Georgia’s history, with lynching at its peak and the convict leasing system operating at full capacity, a system that forced Black men accused on false charges into labor camps that were in many ways worse than slavery. The search shifted to identifying the women.
Dorothy Williams’s grandson, James Williams, who lived in Savannah, was initially skeptical but agreed to meet. He brought a small wooden box that his grandmother had given him before her death. She had said someone would one day ask the right questions. Inside were a delicate leather diary with yellowed pages, a silver locket containing a small photograph, and folded cloth embroidered with symbols.
The diary entries ran from 1894 to 1903 and belonged to Clara, identified as the seated woman in the photograph. Her daughters were Ruth and Esther. James said the family knew them as healers and midwives, but his grandmother always insisted there was more to their story. The entries were precise but intentionally obscure, mentioning night visitors, successful journeys, and supplies purchased in quantities far exceeding what a family of three needed.
One entry from May 1899 read: “Three souls left last Thursday and reached the second house without incident. Word was sent ahead. Worry grows about the next path. Ruth says her hands remember the old ways.
”
Dr. Washington recognized the house in the locket photograph from oral histories: a modest home with a distinctive brick chimney in Atlanta’s Sweet Auburn neighborhood, known in testimonies as “Potter’s House. ” City directory records from 1898 identified Clara Potter as a midwife residing on Howell Street. The name was not a code name at all; it was Clara’s actual surname.
The house still stood at the end of a forgotten side street, partially collapsed behind a metal fence overgrown with kudzu. After two weeks of permits, researchers entered with structural engineers. Under the floor of what had once been the kitchen, Marcus discovered a hidden crawlspace about eight feet square with brick walls and a dirt floor. Carved into the bricks were the same symbols embroidered on the cloth from James’s box.
On the opposite wall, in rougher carving, were dozens of names, some with dates beside them. “These are the people they helped,” Dr. Washington said. “This is a record of everyone who passed through this house seeking safety.
” Among the names were families still present in Atlanta’s Black community, including Johnsons, Crawfords, and Washingtons, who had no idea their ancestors had been rescued by three women missing from the official historical record. Near the bottom of the list, carved in more elegant script, were the words: “We who hid here honor those who hid us. The hands that guided us will never be forgotten. 1899 to 1903.
”
Over subsequent weeks, researchers documented every detail of the cellar, matched names against census records, church registers, and death certificates, and gradually mapped the scale of the network. James shared family stories: women known for their secrecy, food always prepared in extra quantity, visitors arriving late at night and gone by morning, and warnings passed down about keeping certain truths hidden. The diary’s coded language became clearer. “Delivered a healthy child” often meant successfully transporting someone to the next safe point.
“Complications arose” meant imminent danger or encounters with authorities. “Mother and child recovering well” meant someone had reached safety in another city or state. One entry from August 1899 described “a difficult birth” and noted: “We had to use the old sign to reach J. B.
for documents. He helped as he always does. ” J. B.
was the photographer, providing forged identification papers that allowed people to become new individuals without criminal records or arrest warrants. Researchers identified connections to additional safe houses across Georgia, Alabama, and South Carolina, each operated by people working under ordinary job covers: teachers, churchwomen, laundresses, and cooks, individuals made invisible to white authorities by their professions yet accessible to Black communities in need. Routes had coded names, including the river route to Savannah, the mountain route north toward Tennessee, and the western route toward Birmingham. Clara, Ruth, and Esther stood out for their longevity.
Most safe house operators worked for a year or two before danger became too great. These women worked from approximately 1895 to 1903, eight years of continuous hazardous work. Clara died in 1904, Ruth in 1911, and Esther lived until 1923. Word of the discovery spread through Atlanta’s Black community, and descendants began contacting the center.
A 73-year-old man named Thomas Crawford brought a faded letter written by his great-grandfather in 1900. The letter described an escape from a rural labor camp where the man had been imprisoned on false charges, and mentioned three unnamed women who provided food, clothing, and guidance to Savannah. “Their hands knew the way when mine were bound,” the letter read. A woman named Gloria Henderson, 81, shared photos of her grandmother, a teenager who fled Atlanta in 1898 and was helped by three women who held her hand through the night and told her she deserved a better life.
Not everyone accepted the findings. Some historians questioned whether the hand positions were genuine Underground Railroad signals or simply casual poses. Others argued the evidence was circumstantial, that a diary and carved names were not definitive proof. Dr.
Washington pushed back: “If they had been white women, their courage would be celebrated without question. But because they were Black women working outside official channels, we suddenly need impossible standards of proof. ” Marcus recognized part of the resistance came from professional investment in the established timeline, since accepting the network’s continuation meant acknowledging that emancipation had not ended oppression and that the struggle had continued in unrecognized ways. Dr.
Hayes organized a symposium at the center. James Williams spoke before a packed hall: “These women risked everything. Not for glory or recognition, but because it was the right thing to do. The evidence is not only in the documents.
It is in the descendants who are alive today because Clara, Ruth, and Esther refused to stay silent and safe. ”
National media covered the story. The Atlanta History Center mounted an exhibition called “Hands of Deliverance: The Secret Network of the Post-Emancipation South,” featuring the photograph, detailed explanations of the hand signals, diary excerpts, and images of the carved cellar names. Researchers identified more than three hundred descendants of people the network had helped, and their photos lined the exhibition wall, each person holding a placard with their ancestor’s name and the year they received aid.
The house was designated a historic landmark by the city, and fundraising began to restore it as an educational center. The cellar would be preserved exactly as found. Dr. Washington published a comprehensive book documenting the network and identifying similar operations across the South, which became essential reading in African American history courses nationwide.
In September 2021, exactly two years after Marcus first noticed the unusual hand positions, a ceremony was held at the restored house. Descendants of Clara, Ruth, and Esther gathered with descendants of those they had helped, more than two hundred people representing five generations. A bronze plaque near the entrance read: “In this house, Clara, Ruth, and Esther Potter led more than 200 souls to safety between 1895 and 1903. Their hands spoke when words were dangerous.
Their courage saved lives when silence was easier. ”
Marcus, now completing a doctoral degree focused on encoded resistance in the post-Reconstruction South, reflected on the Tuesday morning he almost moved on to the next item in the box. Dr. Hayes gave the closing address: “This photograph teaches us that our ancestors were intelligent, strategic, and brave.
They found ways to resist that we are only beginning to understand. They knew they were leaving proof that they existed, that they resisted, and that they prevailed. Every person they saved was a victory. Every name carved in that cellar was a declaration: we were here, we mattered, we changed lives.
