    The Challenge

    Complex family separation mystery - Before 1898, New York City vital records for Queens were not consistently recorded, but Terrence died in 1874. Two marriages produced four children: James, Mary Ann, Elizabeth (with first wife Ann Higgins who died 1864) and Miles (with second wife Cornelia Bedell who died May 1874). When Terrence died in November 1874, the four orphaned children were separated among relatives in New York and Kentucky with no family stories passed down."

  • Historical probate document titled 'Surrogate's Court' from Queens County, New York, regarding the estate of Terrence O'Brien, deceased. Contains handwritten information about the estate, including the administrator's name, date, and signatures.

    The Breakthrough

    Probate records revealed the key to family reunion. Line-by-line transcription discovered James Henry was sent to 'Uncle Patrick O'Brien' in Newport, Kentucky. Systematic Kentucky genealogical research located Patrick O'Bryan's family. DNA analysis confirmed a large cluster of matches sharing common ancestors Patrick O'Bryan and Mary McNamara, genetically proving the 150-year-old probate document was accurate and Patrick was indeed Terrence's brother.

    The Result

    The Result

    DNA analysis identified New York and Kentucky branches of the O'Brien family separated for 150+ years. Large cluster of matches connected descendants to common ancestors Patrick O'Bryan and Mary McNamara. When we cross-referenced DNA matches with the 150-year-old probate document, the evidence was compelling: James H. O'Brien was indeed Terrence's brother. This transforms foundational genealogy into a potential family reunion story, with ongoing efforts to contact living descendants. We also documented James H. O'Brien's career as a Congressman and successful scale manufacturing business that employed his half-brother Miles for over 20 years.
