Tatiana Schlossberg, the granddaughter of JFK, has died from blood cancer at the age of 35, just six weeks after she revealed her diagnosis.
The Kennedy scion’s death was announced on Tuesday via the social media accounts for the JFK Library Foundation on behalf of her heartbroken relatives.
‘Our beautiful Tatiana passed away this morning. She will always be in our hearts,’ the post reads, signed by ‘George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory’.
New York-born Schlossberg revealed that she had been diagnosed with acute myeloid leukemia in a New Yorker article published November 2025.
The environmental journalist wrote that she had no symptoms and was ‘one of the healthiest people I knew’ when the shock diagnosis came.
Doctors only found the disease through routine blood tests after she gave birth to her second child.
She was the daughter of Caroline Kennedy, whose parents were John F Kennedy and Jackie Kennedy, and designer Edwin Schlossberg.
Schlossberg leaves behind her husband, physician George Moran, and their two children, Edwin, three, and Josephine, one.

Writing in the New Yorker about her diagnosis, Schlossberg said that ‘could not believe ‘ the doctors were talking about her when they said she would need chemotherapy and a bone marrow transplant.
‘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,’ she wrote.
Schlossberg said her parents and her siblings, Rose and Jack, supported her through months of grueling medical treatments.
‘[My family has] held my hand unflinchingly while I have suffered, trying not to show their pain and sadness in order to protect me from it. This has been a great gift, even though I feel their pain every day,’ she wrote.
She also addressed the so-called ‘Kennedy curse’ in her essay, saying that she did not want to add ‘a new tragedy’ to her mother Caroline’s life.
Caroline was five years old when her father was assassinated, and she lost her only living sibling, John F. Kennedy Jr., in a plane crash.
‘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,’ Schlossberg wrote.
‘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.’
