Grenville T. Emmet III, affectionately known to family and friends as "Jeremy," passed away peacefully at his home in Boynton Beach, Florida, on July 16, 2026. He was 87.

A devoted husband, father, friend, accomplished athlete, and proud Brooks School and Harvard University alumnus, Jeremy lived a life marked by family, enduring relationships, and a deep sense of stewardship and service—for his family, his friendships, his heritage, and the institutions he loved.

Born October 13, 1938, in New York, New York, he was the eldest son of Anne Eustis Emmet and Grenville T. Emmet, Jr. At age 11, Jeremy entered Brooks School, where he would spend the next seven years as a boarding student. Under the leadership of Headmaster Frank Ashburn, Brooks became far more than a school—it became the foundation upon which he built his character, his friendships, and many of the values that guided him throughout his life. He remained a devoted supporter of Brooks School and took particular pride when his grandchildren, Emmet Janney '21 and Caroline Janney '23, continued the family tradition.

A gifted all-around athlete, Jeremy earned distinction on the football field, squash court, and baseball diamond. His athletic accomplishments later earned him induction into the Brooks School Athletic Hall of Fame. While at Harvard, he was captain of the squash team and became the number-one-ranked collegiate player in the country. He also was an accomplished based ball player where he became starting pitcher of the varsity team and had hopes of pursuing baseball at a professional level until a career-ending arm injury ended that possibility. Baseball remained one of his lifelong sports passions, and he was an unwavering Boston Red Sox fan.

After graduating from Harvard, Jeremy served as an officer in the United States Army Reserve before working for the Democratic National Committee on John F. Kennedy's presidential campaign. He met his future wife, Patricia Butler while working on the campaign and together they co-authored What the Pros Know, drawing upon their experiences in political and public life. He went on to a distinguished career in banking, serving as the youngest Senior Vice President of International Banking at Marine Midland Bank. When his wife, Patricia, became ill with cancer, he left banking and together, they purchased and ran WAGE Radio in Leesburg, Virginia, allowing them to move closer to family and become important members of the community as the only source of daily news in Loudoun County. Jeremy's commitment to the Loudoun County extended well beyond the radio station. He also served on the Board of Directors of Loudoun Hospital (now Inova Loudoun Hospital).

Jeremy took great pride in his family's rich history and tradition of public service. A descendant of the Irish patriot Robert Emmet and his brother Thomas Addis Emmet, who emigrated to the United States and became Attorney General of New York, Jeremy cherished his Irish heritage. He returned often to County Cork for family reunions and holidays, sharing Ireland's beauty, traditions, and history with his children and grandchildren. No family celebration was complete without Jeremy raising a glass to his wife Lucinda “Cindy” Emmet before concluding with his signature toast, "Emmet go Bragh!” as a proud celebration of his Irish heritage.

Jeremy was the great-grandson of Levi P. Morton, former Vice President of the United States. Morton’s daughter, Edith Livingston Morton married William Corcoran Eustis, establishing his family’s lifelong connection to Oatlands Plantation by purchasing the historic Virginia estate. The property was later donated to the National Trust for Historic Preservation and remained a special place for him as a devoted supporter of the Oatlands Foundation and as a member of its Board of Directors for many years.

He delighted in sharing the rich history of both his Irish ancestry and of Oatlands. Between stories of visits by President Franklin D. Roosevelt and First Lady Eleanor Roosevelt to the distinguished public service of his grandfather, Grenville T. Emmet, who served as Roosevelt’s United States Ambassador to the Netherlands and Austria, Jeremy cherished history not only for the past but as a living inheritance to be understood, preserved, and passed on to future generations.

Jeremy suffered profound loss when Patricia passed away from cancer in 1984. He eventually found love and happiness again when, in 1999, he married his high school sweetheart, Lucinda ("Cindy") Doubleday, beginning a happy, 26-year chapter filled with travel, laughter, family, and enduring companionship and devotion.

Beyond his family heritage, Jeremy loved the places that became part of his own family’s history. Countless summers, sporting traditions, family gatherings, and indelible memories took place on Fishers Island, New York, and in Watch Hill, Rhode Island, where he will be laid to rest later this year.

Jeremy’s final wish was to return home and be surrounded by family, and that wish was fulfilled. With Cindy by his side, he passed away peacefully the following morning.

Jeremy is survived by his beloved wife, Lucinda (“Cindy”) Emmet; his sister, Anne Emmet; his children, Grenville T. “Sean” Emmet IV, Patrick Emmet (Liza), Bradford Emmet (Kimberly), and Samantha Janney (Ty); his stepchildren, Edward "Ned" Doubleday, Jennifer Brown, and Stephen Doubleday; seven cherished grandchildren: Jonathon, Austin, and Madison Emmet; Emmet and Caroline Janney; Morgan and Devon Emmet.

He was predeceased by his parents, Anne Eustis Emmet and Grenville T. Emmet, Jr.; his beloved first wife, Patricia Butler Emmet; and his sister, Edith Emmet.

Jeremy lived a full and accomplished life, with his greatest legacy being the family he loved, the friendships he nurtured, the history he preserved, and the example he left behind.

The family wishes to express gratitude to the hospice team at Trustbridge. In lieu of flowers, the family requests donations be made in Jeremy’s name to Brooks School in North Andover, MA. Click Here to Donate Online
