Tatiana Schlossberg, Writer and Daughter of Caroline Kennedy, Dies at 35
Tatiana Schlossberg, a talented writer and the middle child of Caroline Kennedy and Edwin Schlossberg, passed away on Tuesday, December 30, at the age of 35. The news was confirmed by the JFK Library Foundation on behalf of her extended family.
“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the post read, signed by “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”
Publicly Shared Leukemia Diagnosis
Schlossberg revealed she had been diagnosed with acute myeloid leukemia in a deeply personal essay published by The New Yorker in November 2025. Doctors discovered the disease while she was hospitalized after giving birth to her second child, a daughter. She and her husband, George Moran, whom she married in 2017, also share a son.
“I did not could not believe that they were talking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t sick. I didn’t feel sick,” she wrote, describing the shock of her diagnosis and the intensive treatments, including chemotherapy and a bone-marrow transplant, that followed.
Family Support During Her Illness
Tatiana’s family played a critical role during her treatment. Her older sister, Rose, was a match for a stem cell donation, and her younger brother, Jack, provided additional support despite being only a half-match.
“[My family has] held my hand unflinchingly while I have suffered, trying not to show their pain and sadness to protect me,” Schlossberg wrote.
Personal Reflections and Family Legacy
Tatiana’s mother, Caroline Kennedy, endured profound losses in her life, including the assassination of her father, President John F. Kennedy, and the death of her brother, John F. Kennedy Jr. Tatiana expressed the heartbreak of adding more grief to her family in her final months.
“For my whole life, I have tried to be good, to be a good student and a good sister and a good daughter… Now I have added a new tragedy to her life, to our family’s life, and there’s nothing I can do to stop it,” she wrote.
Advocacy and Critique
While fighting leukemia, Schlossberg also addressed issues regarding her mother’s cousin, Robert F. Kennedy Jr., who was appointed Health and Human Services Secretary during her illness. She criticized policies she felt could impact cancer research and patient care, highlighting the urgency of medical treatments and access for women.
Focus on Family and Love
In her final months, Tatiana concentrated on her husband and children, cherishing every moment.
“George would go home to put our kids to bed and come back to bring me dinner. He is perfect, and I feel so cheated and so sad that I don’t get to keep living the wonderful life I had,” she reflected.
She also shared her deep fears about leaving her children too young to remember her fully, while emphasizing the importance of living in the present and creating memories.
Educational and Professional Achievements
Tatiana earned a BA in History from Yale and a master’s in American history from the University of Oxford. She was a passionate environmental writer and had plans to pursue research on ocean conservation prior to her illness.
“My son knows that I am a writer and I write about our planet… I remind him a lot, so that he will know I was not just a sick person,” she wrote.
