Tatiana Schlossberg, Kennedy Family Member and Author, Dies at 35
Tatiana Schlossberg — the daughter of Caroline Kennedy and granddaughter of the late U.S. President John F. Kennedy — passed away on Tuesday, December 30, following a diagnosis of a serious cancer. She was 35 years old.
“Our cherished Tatiana left us this morning. She will forever remain in our hearts,” the JFK Library Foundation communicated in a statement posted on Instagram, signed by Tatiana’s husband, George Moran, their two children, Edwin, aged 3, and Josephine, who is 19 months old, her parents, Edwin Schlossberg and Caroline Kennedy, her brothers and sisters, Jack and Rose Schlossberg, and her brother-in-law, Rory Schlossberg.
Born in New York City in May of 1990, Tatiana became a member of the well-known Kennedy family, with Caroline as her mother and John and his widow, Jacqueline Kennedy Onassis, as her grandparents.
After completing a bachelor’s degree in history from Yale University in 2012 and a master’s degree from the University of Oxford in 2014, Tatiana pursued a career in journalism, working as a reporter for The New York Times until 2017. Two years later, she released her debut book, Inconspicuous Consumption: The Environmental Impact You Don’t Know You Have.

Regarding her personal life, Tatiana married Moran in September 2017 after they initially met as undergraduates at Yale. The couple welcomed their son, Edwin, in early 2022 and their daughter, Josephine, in May 2024.
In November 2025, Tatiana shared in a New Yorker essay that she had been given approximately one year to live after being diagnosed with acute myeloid leukemia. She discovered her illness, which included “a rare genetic alteration called Inversion 3”, after her doctor noticed an irregularity in her white blood cell count following the birth of her second child. She was initially informed that she would need to undergo several months of chemotherapy and receive a bone-marrow transplant.
“I simply did not — could not — believe that they were speaking about me. I had swum a mile in the pool the day before, nine months pregnant. I wasn’t unwell. I didn’t feel sick. I was actually one of the healthiest people I knew,” she wrote. “I had a son whom I loved more than anything and a newborn I needed to care for.”
As she navigated her health challenges, Tatiana relied on Moran for unwavering support.
“George did everything for me that he possibly could,” she noted. “He spoke with all the doctors and insurance representatives that I didn’t want to engage with; he slept on the floor of the hospital; he didn’t become upset when I was reacting to the steroids and yelled at him that I didn’t prefer Schweppes ginger ale, only Canada Dry. He would return home to put our children to bed and come back to bring me dinner.”
She added: “I know that not everyone can be married to a physician, but, if you can, it’s a very beneficial idea. He is perfect, and I feel so deprived and so saddened that I won’t get to continue experiencing the wonderful life I had with this kind, humorous, handsome genius I managed to find.”
After having her daughter, Tatiana underwent a bone-marrow transplant at Memorial Sloan Kettering and received chemotherapy treatments at home. However, following participation in a clinical trial of CAR-T-cell therapy — a form of immunotherapy designed to combat certain blood cancers — in January 2025, she was informed of her prognosis.

“My first thought was that my children, whose faces reside permanently on the inside of my eyelids, wouldn’t remember me,” she recalled. “My son might have a few memories, but he’ll likely begin to confuse them with pictures he sees or stories he hears. I didn’t ever really get to nurture my daughter — I couldn’t change her diaper or give her a bath or feed her, all due to the risk of infection after my transplants. I was absent for nearly half of her first year of life. I don’t know who, truly, she thinks I am, and whether she will feel or remember, when I am gone, that I am her mother.”
Tatiana went on to express her gratitude to her parents and siblings for assisting in the care of her children during her illness.
“They have held my hand steadfastly while I have suffered, attempting not to display their pain and sadness in order to shield me from it,” she wrote. “This has been a tremendous gift, even though I feel their pain every day.”
Tatiana is survived by Moran, her two children, her parents and her siblings.
