Tatiana Schlossberg, the granddaughter of former President John F. Kennedy, has tragically passed away at the age of 35. She succumbed to blood cancer just six weeks after publicly disclosing her diagnosis.

The somber news was shared on Tuesday through the social media channels of the JFK Library Foundation, delivering a heartfelt message from her grieving family.

“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the announcement read, a message signed by her loved ones: George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose, and Rory.

Tatiana, a New York-born environmental journalist, had revealed in November that she was diagnosed with acute myeloid leukemia in May 2024. Her disclosure came in a poignant piece for the New Yorker, where she expressed her disbelief at the diagnosis, noting she had felt perfectly healthy at the time.

Writing in the New Yorker, Tatiana said 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.

It is the latest tragedy to befall Caroline, who lost her father to an assassin’s bullet when she was five years old, her only sibling, JFK Jr, in a plane crash years later, and her mother to lymphoma in 1994, when the iconic former first lady was just 64.

Tatiana is survived by her husband, physician George Moran, and their two children, Edwin, three, and Josephine, one. 

Writing in the New Yorker about her diagnosis, Tatiana said that she ‘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. 

Tatiana 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. 

‘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.’

The Kennedy family has also endured assassinations, drug overdoses, tragic accidents and scandal.

The US dynasty’s most famous death was that of then-president JFK, who was shot by Lee Harvey Oswald on November 22, 1963. 

JFK was in Texas with Jackie, and then-vice president Lyndon B Johnson, preparing to deliver a speech on the strength of the US, but he never reached the podium.

The president was shot three times as he rode in an open-top limousine, waving to crowds in Dallas.

Seated to his left was the first lady, his wife of ten years, who cradled him and screamed out for help following the shocking assassination, which was captured by TV crews and reporters in real time.

Three shots were fired in total. The first bullet missed, while the second struck JFK near the base of the back of his neck and exited out of the front of his neck.

The third bullet entered the back of his head on the right and exited out the same side, causing the massive wound that ultimately killed him.

JFK’s younger brother, Robert, was also brutally gunned down, by a man named Sirhan Sirhan, who shot two or three rounds at him just five years after JFK was killed.

Tragedy struck the Kennedy family once more a generation later when the late president’s beloved son, JFK Jr, crashed his small Piper Saratoga plane into the ocean around seven miles from Martha’s Vineyard in 1999.

The journalist and publisher, 38, was on his way to his cousin’s wedding with his wife, fashion publicist Carolyn Bessette Kennedy and her sister Lauren Bessette.

His plan on the day of the flight on July 16 was to fly with his wife, 33, and sister-in-law, 34, to Martha’s Vineyard to drop Lauren off, before continuing with Carolyn to Hyannis Port, Massachusetts.  

But the trio died around seven miles from Martha’s Vineyard after it is thought he lost his bearings over the Atlantic Ocean due to poor visibility and a lack of training. 

In her New Yorker essay, Tatiana also slammed her mother’s cousin, Robert F Kennedy Jr, who is Donald Trump’s Secretary of Health and Human Services, as the family ’embarrassment’.

‘I watched from my hospital bed as Bobby, in the face of logic and common sense, was confirmed for the position, despite never having worked in medicine, public health, or the government,’ she wrote. 

‘I watched as Bobby cut nearly a half billion dollars for research into mRNA vaccines, technology that could be used against certain cancers; slashed billions in funding from the National Institutes of Health, the world’s largest sponsor of medical research; and threatened to oust the panel of medical experts charged with recommending preventive cancer screenings.’ 

She dedicated much of her essay to thanking other family members for supporting her through the most difficult months of her treatment. 

‘[George] would go home to put our kids to bed and come back to bring me dinner. I know that not everyone can be married to a doctor, but, if you can, it’s a very good idea,’ she wrote. 

‘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.’
