Environmental journalist Tatiana Schlossberg revealed her terminal cancer diagnosis in November 2025.
Tatiana — who is the granddaughter of late president John F. Kennedy and former first lady Jacqueline Kennedy Onassis — confirmed in an essay published by The New Yorker that she was battling acute myeloid leukemia and was given a year to live by doctors.
She learned that she has a “rare mutation called Inversion 3” that could not be “cured by a standard course” of treatment shortly after welcoming her daughter, Josephine, in May 2024. (Tatiana and her husband, George Moran, also share a son, Edwin Garrett Moran, who was born in 2022.)
“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. I was actually one of the healthiest people I knew,” Tatiana wrote in The New Yorker. “I had a son whom I loved more than anything and a newborn I needed to take care of.”
News broke in December 2025 that Tatiana died. She was 35.

George Moran
Tatiana Schlossberg met her future husband, George Moran, while they were both undergraduates at Yale University. Moran became a doctor at Columbia University’s Vagelos College of Physicians and Surgeons, while Schlossberg worked for The New York Times, Vanity Fair and The Washington Post as an environmental reporter.
The New York Times reported in September 2017 that the couple had tied the knot at the Kennedy family home in Martha’s Vineyard in a ceremony officiated by former Massachusetts governor Deval Patrick.
Tatiana’s younger brother, Jack Schlossberg, announced on NBC’s Today in 2022 that his sister and her husband had welcomed their first baby, a son named Edwin Moran.
“I can’t get away from them,” Jack said of his sister and his newborn nephew. “I love them.”
Tatiana and George welcomed their youngest child, a daughter, in 2024. They have chosen to keep her name private.
Following her terminal cancer diagnosis, Tatiana credited George for his immense support following her cancer diagnosis.
“George did everything for me that he possibly could. He talked to all the doctors and insurance people that I didn’t want to talk to; he slept on the floor of the hospital; he didn’t get mad when I was raging on steroids and yelled at him that I did not like Schweppes ginger ale, only Canada Dry. He would go home to put our kids to bed and come back to bring me dinner,” she recalled in the New Yorker.
Tatiana added, “I know that not everyone can be married to a doctor, but, if you can, it’s a very good idea. He is perfect, and I feel so cheated and so sad that I don’t get to keep living the wonderful life I had with this kind, funny, handsome genius I managed to find.”
Edwin Moran
Tatiana’s younger brother, Jack, announced that he’d become an uncle during a 2022 interview on NBC’s Today.
“[Tatiana’s son’s] name is Edwin but I like to call him Jack,” the Kennedy heir teased.
In her New Yorker essay, Tatiana recalled that Edwin’s visits to the hospital were rare bright spots as she received cancer treatment.
“My son came to visit almost every day. … The nurses brought me warm blankets and let me sit on the floor of the skyway with my son, even though I wasn’t supposed to leave my room,” she recalled.
Tatiana reflected on a bonding experience with her son as her hair began to fall out during treatment.
“My hair started to fall out and I wore scarves to cover my head, remembering, vainly, each time I tied one on, how great my hair used to be; when my son came to visit, he wore them, too,” she said.
Josephine
Tatiana and George welcomed their daughter, Josephine, in May 2024. After giving birth, Tatiana spent five weeks at Columbia-Presbyterian Hospital and was transferred to Memorial Sloan Kettering to undergo a bone-marrow transplant. She later underwent chemotherapy at home.
She wrote in her New Yorker essay that one of her biggest fears after receiving a terminal diagnosis was that her newborn daughter wouldn’t remember her.
“My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears,” she wrote. “I didn’t ever really get to take care of my daughter — I couldn’t change her diaper or give her a bath or feed her, all because of the risk of infection after my transplants. I was gone for almost half of her first year of life. I don’t know who, really, she thinks I am, and whether she will feel or remember, when I am gone, that I am her mother.”
When the family announced Tatiana’s death in December 2025, it was revealed that her daughter’s name is Josephine.
John F. Kennedy and Jackie Kennedy
Tatiana is the granddaughter of late President John F. Kennedy and former first lady Jackie Kennedy. The Kennedys shared daughter Caroline Kennedy and son John F. Kennedy Jr. (They also lost two children, daughter Arabella and son Patrick.)
President Kennedy was killed at age 46 in a fatal shooting on November 22, 1963, in Dallas, Texas. Jackie later married Greek-Argentine magnate Aristotle Onassis, who died at age 69 in 1975. Jackie succumbed to Non-Hodgkin’s lymphoma at age 64 in May 1994.
Caroline Kennedy
John and Jackie Kennedy welcomed daughter Caroline Kennedy in November 1957. She was only 5 years old when her father was assassinated in 1963.
As an adult, Caroline worked at New York City’s Metropolitan Museum of Art, where she met her future husband, Edwin Schlossberg. They tied the knot at Our Lady of Victory Church in Centerville, Massachusetts in 1986 and later welcomed three children: Rose, Tatiana and Jack.
Caroline eventually followed in her family’s footsteps by entering politics as an ambassador to Australia and Japan during Joe Biden and Barack Obama’s presidential administrations.
Tatiana credited her parents and siblings with helping to raise her two children while she underwent grueling cancer treatment.
“My parents and my brother and sister, too, have been raising my children and sitting in my various hospital rooms almost every day for the last year and a half. They have held my hand unflinchingly while I have suffered, trying not to show their pain and sadness in order to protect me from it,” she wrote in her New Yorker essay. “This has been a great gift, even though I feel their pain every day. For my whole life, I have tried to be good, to be a good student and a good sister and a good daughter, and to protect my mother and never make her upset or angry. 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.”
Edwin Schlossberg
Caroline’s husband Edwin Schlossberg is an artist and designer. He founded the firm ESI Design and has written several books about design philosophy.
Edwin was appointed to the Commission of Fine Arts by President Obama in 2011, after receiving the prestigious National Arts Club Medal of Honor in 2004.
Rose Kennedy Schlossberg
Caroline and Edwin’s eldest daughter, Rose Schlossberg, arrived in June 1988 and was named after her maternal great-grandmother, Rose Fitzgerald Kennedy.
She attended Harvard University, where she once gave Lindsay Lohan and her then-girlfriend Samantha Ronson a campus tour, according to the Boston Herald. She later received her master’s degree in interactive telecommunications from New York University.
Rose has worked as a production assistant on the TV show Brick City and the 2012 documentary Hard Times: Lost on Long Island. She co-wrote and produced the Peabody Award-winning documentary series The Kalief Browder Story in 2017 and helped open a permanent exhibit for her late grandfather, John F. Kennedy, at the Kennedy Center in 2022.
She married restaurateur Rory McAuliffe in California in 2022.
John ‘Jack’ Bouvier Kennedy Schlossberg
Caroline and Edwin’s youngest child, son Jack Schlossberg, was born in January 1993.
As an adult, he became popular on social media for his shirtless selfies and pop culture clapbacks — including criticizing American Horror Story creator Ryan Murphy’s planned series about Jack’s late uncle John F. Kennedy Jr. and his wife Carolyn Bessette Kennedy. (The couple were killed in a 1999 plane crash, along with Carolyn’s sister Lauren Bessette.)
In November 2025, Jack announced plans to run for Congress in New York’s 12th congressional district in the 2026 midterm elections.
“I’m not running because I have all the answers to our problems. I’m running because the people of New York 12 do. I want to listen to your struggles, hear your stories, amplify your voice, go to Washington and execute on your behalf,” he wrote via Instagram.
Jack continued, “There is nowhere I’d rather be than in the arena fighting for my hometown. Over the next eight months, during the course of this campaign, I hope to meet as many of you as I can. If you see me on the street, please say hello. If I knock on your door, I hope we can have a conversation. Because politics should be personal.”
Robert F. Kennedy Jr.
Like most of her family, Tatiana has had a strained relationship with her cousin Robert F. Kennedy Jr. since he endorsed Donald Trump in the 2024 presidential election. RFK Jr. was later appointed by Trump to lead the Department of Health and Human Services, which drew concern over his history of vaccine skepticism.
Tatiana wrote about her rift with her cousin in her New Yorker essay, revealing that his confirmation to the HHS role added stress during her illness. She pointed out that her husband George’s job at Columbia University was potentially in danger because the school was “one of the Trump Administration’s first targets in its crusade against alleged antisemitism on campuses.”
Cheryl Hines Responds to People Who Think She Should Leave RFK Jr.
“If George changed jobs, we didn’t know if we’d be able to get insurance, now that I had a preëxisting condition,” she wrote. “Bobby is a known skeptic of vaccines, and I was especially concerned that I wouldn’t be able to get mine again, leaving me to spend the rest of my life immunocompromised, along with millions of cancer survivors, small children, and the elderly.”
Tatiana unequivocally distanced herself from RFK’s statement that “there’s no vaccine that is safe and effective” during a 2023 appearance on the “Lex Fridman Podcast.”
“Bobby probably doesn’t remember the millions of people who were paralyzed or killed by polio before the vaccine was available,” she added. “My dad, who grew up in New York City in the nineteen-forties and fifties, does remember. Recently, I asked him what it was like when he got the vaccine. He said that it felt like freedom.”
