A Documentary Biography Series
Hidden Bonds
The O'Brien Family of Jamaica, Queens
1830–Present | From Famine Ireland to DNA Reunion
Two brothers. Four orphans. One hidden fortune.
And the family bonds that survived it all.
When Terrence O'Brien died on November 21, 1874, he left behind four orphaned children from two marriages — and a secret. The probate valued his estate at just $400. Years later, $11,000 in government bonds was discovered hidden in the kitchen wall of his hotel.
The four children were scattered to relatives across three states. James Henry, age 14, was sent to his uncle Patrick O'Brien in Kentucky. Mary Ann and Elizabeth stayed in Jamaica with their maternal uncle. Baby Miles, just 18 months old, went to his great aunt.
They had no shared maternal family to hold them together. By all rights, they should have lost each other forever.
But they didn't.
Hidden Bonds traces their story from famine Ireland to Jamaica, Queens — from scattered orphans to DNA reunion. Along the way, we discovered they carried the genetic signature of Brian Boru, High King of Ireland. The Catholic branch of the Royal House of Thomond, thought extinct for centuries, had survived in these Irish immigrants.

Prologue & Background
Prologue: The Blood of Kings
They were descended from the High King who united Ireland. For three centuries, the Penal Laws tried to erase them. Then DNA proved what history couldn't destroy—a thousand years of royal blood connecting two Famine refugees to Brian Boru himself.
Read the Prologue →Companion Piece: County Clare in the Famine Years
County Clare lost 42% of its farms. It had the highest eviction rate in Ireland. The Ennistymon workhouse saw nearly 5,000 deaths. This is the land Patrick and Terrence O'Brien fled in the late 1840s—the land where their family name once meant royalty, reduced to devastation. Explore what two teenage brothers witnessed before they embarked for America, never to see each other again.

He lost both parents before he turned two. He carried the DNA that would reunite the family 150 years later. And when his half-brother James remarried, Miles stood beside him as witness.
Read Episode 6 →Episode 7: Miles Murtha O'Brien — The Carpenter Who Built with Double Vision (1904–1984)

Read Episode 7 →Episode 8: The Kentucky Brother — Patrick O'Bryan and the DNA Reunion
Two Irish brothers. 800 miles apart. 150 years of silence. Both died on November 21st — exactly 39 years apart. DNA testing finally proved what a single probate line had always suggested.
Read Episode 8 →Epilogue: The DNA Reunion
When Terrence O'Brien died in 1874, a single line in the probate document mentioned "Uncle Patrick O'Brien in Newport, Kentucky." For 150 years, that reference stood alone—no other evidence connected the New York and Kentucky families. Then DNA testing proved what documents couldn't.
Read the Epilogue →The DNA Discovery
In 2018, genealogical research began to unravel the mystery of the O'Brien family. The 1875 probate document — with its single reference to "Uncle Patrick O'Brien in Newport, Kentucky" — provided a crucial lead.
Systematic Kentucky genealogical research located Patrick O'Bryan's family. DNA analysis confirmed what the documents suggested: a large cluster of matches sharing common ancestors Patrick O'Bryan and Mary McNamara.
But the DNA revealed something even more remarkable. Y-DNA testing connected the O'Brien descendants to the Royal House of Thomond — the family of Brian Boru, High King of Ireland (941–1014). The Catholic branch of Irish royalty, thought extinct for centuries, had survived in these famine refugees.
The genetic evidence proved the 150-year-old probate document was accurate. Patrick was indeed Terrence's brother. The Kentucky cousins and the New York descendants were one family — separated for over a century, now reunited through DNA.
The hidden bonds — both the government securities in the wall and the family connections across the miles — had finally been found.
