Tatiana Schlossberg, the youngest granddaughter of President John F. Kennedy and mother to two young children, tragically died on Tuesday at age 35 following a terminal battle with cancer, the JFK Library Foundation announced.
“Our beautiful Tatiana passed away this morning,” the foundation posted on its Instagram page, signed by “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”

“She will always be in our hearts.
In a personal essay published in the New Yorker last month, the mother of two revealed that she had less than a year to live after being diagnosed with myeloid leukemia with a rare mutation.
“Maybe my brain is replaying my life now because I have a terminal diagnosis, and all these memories will be lost,” Schlossberg heartbreakingly wrote in the essay, published on Nov. 22 – the 62nd anniversary of her grandfather’s 1963 assassination.
In January, she joined a clinical trial of CART-cell therapy, a type of immunotherapy against certain blood cancers, but was tragically given the terminal prognosis.

In her article, Schlossberg agonizingly described the prospect of her children — Edwin, 3, and a 19-month-old daughter — growing up without memories of her.
“My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me. 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 even really get to take care of my daughter – I couldn’t change her diaper or give her a bath or feed her.”

Schlossberg leaves behind her husband, George Moran, their two kids, and her parents, Carolina Kennedy, 67, and Edwin Schlossberg, 80.
She is also survived by her older sister Rose, 37, and younger brother, Jack, 32, who is running for Congress in the 12th Congressional District being vacated by Manhattan Rep. Jerold Nadler.

Schlossberg described how doctors discovered the cancer just hours after she gave birth to her second child in May 2024. She spent the past 18 months in treatment, receiving a bone-marrow transplant, chemotherapy and blood transfusions.
The rare mutation that Schlossberg was diagnosed with – Inversation 3 – is generally seen in older patients.
Schlossberg, who graduated from Yale and has a Master’s degree from Oxford, previously worked as a journalist at The New York Times and published her first book in 2019.

She has been married to urologist George Moran, whom she met as an undergrad at Yale, since 2017.
Schlossberg wrote that her immediate family was helping her raise her two young children amid her treatment, and described the heartbreak of adding further tragedy to her mother’s already turbulent 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,” she said.

“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.”
Caroline Kennedy’s uncle, Robert F. Kennedy, was assassinated in 1968, less than five years after her father’s death.
Her mother, Jackie Kennedy Onassis, died in 1994 at the age of 64 following a short battle with non-Hodgkin lymphoma, which spread to her spinal cord, brain, and liver.
Caroline’s younger brother, John F. Kennedy, Jr., died in 1999 at age 38 in a plane crash that also killed her sister-in-law, Carolina Bessette Kennedy, 33.
Schlossberg is the second of Caroline Kennedy and Edwin Schlossberg’s three children.
