Erin International Expands Operations to the United States

13th May 2025

Ireland’s leading forensic genealogy firm launches U.S. operations, strengthening cross-Atlantic support for estate professionals

Erin International is proud to announce the official launch of our U.S. operations, headquartered in New York. This strategic expansion enhances our ability to serve trust and estate practitioners, solicitors, and fiduciaries on both sides of the Atlantic with our trusted heir search and probate research services.

As a longstanding partner to Irish legal professionals, we understand the sensitivities and legal rigour involved in locating missing beneficiaries, verifying kinship, and supporting probate cases involving complex or international family lines. Our move into the U.S. marks a significant milestone — and reaffirms our commitment to providing high-integrity, court-ready genealogical research to the global legal community.

A Warm Welcome Stateside

We were delighted to officially mark this expansion with a launch event in New York, where CEO and founder Padraic Grennan addressed attorneys, fiduciaries, and professionals from the U.S. estate planning and trust administration sector.

The event celebrated the natural alignment between Irish and American legal traditions in probate and trust work — as well as the deep personal connections that often emerge in cases involving the Irish diaspora.

We were also honoured to be featured in IrishCentral, a leading publication for the global Irish community. The article covers our journey from Dublin to New York, our role in reconnecting families with lost legacies, and how our work supports U.S. attorneys in Surrogate’s Courts and beyond.

“Our rigorous heir search process alleviates the burden on legal professionals and safeguards legacies for rightful heirs.”
— Padraic Grennan, CEO and Founder
