Hidden Bonds Epilogue: The DNA Reunion
The DNA Reunion
When Science Proved What Documents Couldn't
1874–2024 | 150 Years of Silence, Broken
A single line in an 1874 probate document. Five years of dead ends. Then DNA testing proved the connection—and reunited descendants who never knew each other existed.
This epilogue completes the Hidden Bonds documentary biography series. In the Prologue, we traced a thousand years of royal blood from Brian Boru to the Great Famine. Through eight episodes, we followed Terrence O'Brien from teenage refugee to hotel empire builder. Now we close the circle: how 21st-century DNA science validated 150-year-old testimony, reunited two branches of a scattered family, and proved that the blood of kings endures.
"Deceased left him surviving as his only next of kin four children Viz:— James Henry O'Brien a minor over 14 years now residing in Newport Kentucky with his uncle Patrick O'Brien and has no general guardian..."
— 1874 Probate Document, Queens County Surrogate's CourtThe Orphans of Jamaica
When Terrence O'Brien died suddenly on November 21, 1874, he left behind four children and no will. His second wife, Mary Madden O'Brien, had died just six months earlier. The children—ranging from eighteen-month-old Miles Murtha Lawrence to fourteen-year-old James Henry—were scattered among relatives and family friends.
Thomas Higgins, Terrence's maternal uncle by marriage, became guardian for the two girls, Mary Ann and Elizabeth. A Mrs. Madden—likely a relative of Terrence's second wife—took custody of baby Miles. And James Henry, the eldest son, was sent eight hundred miles away to Newport, Kentucky, to live with someone the probate document described as "his uncle Patrick O'Brien."
The Single Line
"James Henry O'Brien a minor over 14 years now residing in Newport Kentucky with his uncle Patrick O'Brien and has no general guardian"
Sworn testimony of Thomas Higgins, January 5, 1875, Queens County Surrogate's Court
This single sentence was the only documented connection between the two branches of the O'Brien family. For 150 years, it would stand alone—a tantalizing hint with no supporting evidence.
150 Years of Silence
The families forgot each other.
In New York, Terrence's descendants remembered him as the immigrant hotel keeper who built a small fortune and died young. They had photographs, property records, census entries, newspaper clippings. They knew about the Union Hotel, the legal battles over his estate, the children scattered after his death.
In Kentucky, Patrick O'Bryan's descendants had their own history—a locomotive engineer who raised his family in Newport, across the river from Cincinnati. Different spelling of the name. Different state. Different life.
No one knew they were the same family.
The research began in September 2018. For five years, traditional genealogical methods hit wall after wall.
Research Begins
Starting with two marriage records—Terrence to Kate and Thomas Henry to Emma Gilbert—the 1880 census reveals a "Thornton Hamall" reference that opens new avenues.
Traditional Research
Irish civil records, church records, census data, naturalization papers, ship manifests, cemetery records, court documents—none connect Terrence and Patrick directly.
DNA Testing
Three descendants of Terrence O'Brien submit DNA samples: Barbara O'Brien Hamall and her brothers Michael and Miles (identical twins).
The Breakthrough
DNA match patterns emerge. Multiple "unrelated" matches all trace to the same Kentucky family—Patrick O'Bryan's documented descendants.
The Traditional Research Dead End
Everything suggested the connection might be real. Terrence O'Brien was an Irish immigrant hotel proprietor in Jamaica, Queens, born around 1833, dead in 1874. Patrick O'Bryan was an Irish immigrant locomotive engineer in Newport, Kentucky, born around 1830, living at the exact location mentioned in the probate document.
The ages were right. The locations matched perfectly. Both were Irish immigrants who arrived in the 1840s–1850s.
But nothing proved they were brothers.
Several factors made traditional research impossible. The surname variations—O'Brien in New York, O'Bryan in Kentucky—could indicate different families entirely. The eight hundred miles between them meant different communities, different churches, different jurisdictions, no evidence of contact or correspondence. Irish Famine-era documentation was fragmentary at best, with limited civil registration before 1864, church records destroyed, working-class emigrants leaving minimal paper trails. And O'Brien is one of the most common surnames in Irish immigration records—without additional identifying information, connections remained speculative.
After five years, there was a compelling circumstantial case but no proof.
The Wall
Traditional genealogical research had reached its absolute limit. The probate document stood alone—a 150-year-old claim with no documentary corroboration.
The Orphan's Grandson
The answer would come from the most unlikely source: the youngest orphan.
Miles Murtha Lawrence O'Brien was just eighteen months old when his father died. He was placed with Mrs. Madden while his siblings were scattered to other guardians. He grew up, married Margaret Egan, and raised a family of his own. He died in 1940, never knowing that his DNA carried proof of a family connection that documents couldn't establish.
His grandchildren—Barbara O'Brien Hamall and her brothers Michael and Miles O'Brien—inherited more than his name. They inherited genetic markers that would solve a 150-year-old mystery.
In November 2023, all three siblings submitted DNA samples. The hypothesis was clear: if Terrence and Patrick were brothers, these testers should match descendants of Patrick's documented children at predictable genetic distances—approximately 20–50 centimorgans, consistent with 3rd or 4th cousin relationships.
The March 2024 Breakthrough
When reviewing Barbara's DNA matches, a pattern emerged.
Multiple matches with seemingly unrelated surnames—Kuptz, Nawrocki, Lyhan, Powell, Browne—all shared something unexpected: every single one traced ancestry to Campbell County, Kentucky, in the 1870s.
When the family trees were built out, they all descended from the same couple: Patrick O'Bryan (1830–1913) and Mary McNamara. The exact family from the 1870 Kentucky census. The exact "Uncle Patrick O'Brien" named in the 1874 probate document.
| Match | Surname | Shared DNA | Segments | Relationship | Geographic Origin |
|---|---|---|---|---|---|
| Match A | O'Bryan | 49 cM | 3 segments | 3rd cousin | Kentucky |
| Match B | O'Bryan | 43 cM | 3 segments | 3rd cousin | Kentucky |
| Match C | Kuptz | 20 cM | 3 segments | 4th cousin | Kentucky/Illinois |
| Match D | Lyhan | 31 cM | 2 segments | 3rd-4th cousin | Kentucky |
| Match E | Powell | 27 cM | 4 segments | 4th cousin | Kentucky/Ohio |
| Match F | Browne | 24 cM | 2 segments | 4th cousin | Kentucky |
The identical twins—Michael and Miles—both matched at exactly 43 cM, providing built-in quality control that confirmed testing accuracy. Three siblings, all matching independently. Multiple descendant lines from both of Patrick's documented children. The probability of this occurring by chance is essentially zero.
DNA Triangulation: How the Evidence Converges
The Unbreakable Proof
The DNA evidence created an unbreakable triangulation pattern:
✓ Multiple descendant lines through both of Patrick's documented children
✓ Consistent centimorgan ranges (20–49 cM) as predicted for the relationship
✓ Three siblings all matching independently
✓ Identical twins showing identical results (quality control)
✓ Geographic correlation—all Kentucky origins
✓ Exact location match with probate document
After 150 years, the 1874 probate document was scientifically validated. Thomas Higgins, testifying under oath on January 5, 1875, had told the truth: Patrick O'Brien of Newport, Kentucky, was indeed Terrence O'Brien's brother.
What DNA Proved
The orphaned infant Miles Murtha Lawrence O'Brien carried genetic markers proving his father's brother relationship to Patrick O'Bryan. Those markers passed through three generations to his grandchildren—Barbara, Michael, and Miles—who, 150 years later, proved the probate testimony accurate through science their ancestors could never have imagined.
A Final Remarkable Detail
In researching the two brothers, one coincidence emerged that defies explanation.
Both Brothers Died on November 21st
Exactly 39 years apart, to the day.
Terrence died suddenly at forty-one, leaving four orphaned children. Patrick lived to see his eighty-third year, surrounded by the family he built in Kentucky. But both brothers drew their last breath on November 21st—a thread connecting them across death as DNA would connect their descendants across time.
What Was Lost, What Was Found
Two teenage boys fled Famine Ireland in the late 1840s. They settled in different states, raised different families, spelled their names differently. Their children lost touch. Their grandchildren never knew each other existed. For 150 years, the connection survived only in a single line of probate testimony—and in their blood.
The Penal Laws tried to erase their ancestors from history. The Great Famine scattered their family across an ocean. A century and a half of silence separated the New York O'Briens from the Kentucky O'Bryans.
But DNA doesn't forget.
Today, the descendants of both brothers know they share more than a surname. They share the genetic signature of the Royal House of Thomond. They carry the blood of Brian Boru. They are the living proof that a family scattered by catastrophe can be reunited by science—and that what history tried to destroy, genetics preserved.
"The Clare Line—Catholic—they were thought to have died out, but through DNA we know they did not."
— Dennis O'Brien, Administrator, O'Brien Surname Project at FTDNAThe titled cousins died out in Parisian exile. The famous Viscounts Clare are extinct.
But the unnamed Catholic O'Briens of Ennis, County Clare—the eight generations who survived the Penal Laws without titles, without records, without hope of recognition—their descendants are still here. In New York. In Kentucky. Across America.
Carrying the blood of kings.
The Research Continues
The Kentucky connection is proven. But another tantalizing thread remains unresolved.
When Miles Murtha Lawrence O'Brien—the eighteen-month-old orphan who survived Jamaica—died in 1940, his obituary stated he "was related to the late Miles M. O'Brien, former president of the Board of Education."
That Miles M. O'Brien (1842–1910) was a towering figure in New York Irish-American society: vice president of the Mercantile National Bank of Manhattan, president of the NYC Board of Education in 1900, director of the American Ice Company, and member of the Lotus, Democratic, and Catholic Clubs. He was born in Limerick, Ireland, and came to America at age twelve—roughly the same emigration period as Terrence and Patrick.
The Murrough Name Pattern
A distinctive detail connects these families: the rare middle name "Murrough" (also spelled Murtha, Murat). Miles Murrough O'Brien of the Board of Education. Miles Murtha Lawrence O'Brien, the Jamaica orphan. This was not a common name—it traces to the ancient Irish Murchadh, meaning "sea warrior." Was this naming pattern coincidence, or evidence of kinship?
Even more intriguing: the Limerick O'Brien family tree shows that Miles M. O'Brien's great-grandmother, Miss Power, married Cornelius O'Brien in 1793—in Ennis, County Clare. The same Clare that gave rise to Terrence and Patrick's line. The same Clare where the Catholic O'Briens maintained their hidden bloodline through the Penal Laws.
Were the New York O'Briens of Jamaica and the prominent Limerick O'Briens actually distant cousins? Did both families descend from the same Clare roots? No DNA evidence has yet emerged to answer these questions. The Limerick connection remains an open research thread—a mystery for future generations of genealogists to solve.
Some stories, it seems, are still waiting to be told.
Evidence Analysis
PRIMARY SOURCE: 1874 Probate Document
Queens County Surrogate's Court records, sworn testimony of Thomas Higgins dated January 5, 1875. States that James Henry O'Brien, eldest son of Terrence O'Brien, was residing "in Newport Kentucky with his uncle Patrick O'Brien." This single reference was the only documented connection between the two families until DNA validation in 2024.
PRIMARY SOURCE: Autosomal DNA Testing (November 2023–March 2024)
Three descendants of Terrence O'Brien tested via AncestryDNA: Barbara O'Brien Hamall (49 cM match to Kentucky O'Bryan descendants), Michael O'Brien (43 cM), and Miles O'Brien (43 cM). The identical twins' matching results provided quality control. Multiple matches to descendants of both Patrick O'Bryan's documented children (Michael b. 1859, Mary b. 1867 per 1870 Campbell County census) create triangulated proof of the brother relationship.
PRIMARY SOURCE: 1870 Campbell County, Kentucky Census
Patrick O'Bryan household documented with wife Mary McNamara and children including Michael (age 11) and Mary (age 3). This census confirms Patrick was living at the location specified in the 1874 probate document at the time James Henry was sent to live with his uncle.
PRIMARY SOURCE: Death Records
Terrence O'Brien died November 21, 1874, in Jamaica, Queens, New York. Patrick O'Bryan died November 21, 1913, in Newport, Kentucky. Both brothers died on the same calendar date, exactly 39 years apart—a documented coincidence confirmed through official death records in both jurisdictions.
METHODOLOGY: DNA Triangulation Analysis
Following Board for Certification of Genealogists (BCG) standards, DNA evidence served as corroborating proof for documentary claims. The triangulation pattern—multiple descendants of Patrick O'Bryan through different children, all matching Terrence's descendants at predicted centimorgan ranges—eliminates coincidental matching. Research conducted 2018–2025 combined traditional genealogical methods with modern genetic analysis.
OPEN RESEARCH: Limerick O'Brien Connection
The 1940 obituary of Miles Murtha Lawrence O'Brien (Brooklyn Daily Eagle) states he "was related to the late Miles M. O'Brien, former president of the Board of Education." Miles M. O'Brien (1842–1910) was born in Lisurland, Strand, near Monagay, County Limerick. His great-grandmother Miss Power married Cornelius O'Brien in Ennis, Clare, Ireland in 1793—suggesting possible Clare origins for both families. The distinctive "Murrough/Murtha" naming pattern appears in both lines. No DNA evidence currently supports this claimed relationship; it remains an open research question.
