Kerry Kennedy Says Cousin Tatiana Schlossberg ‘Left Our World More Joyful, More Beautiful’ Following Her Death at 35

Kerry Kennedy is remembering her cousin Tatiana Schlossberg following her death at the age of 35.

Tatiana, the middle child of Caroline Kennedy and Edwin Schlossberg, died on Tuesday, Dec. 30. The news was announced on social media by the JFK Library Foundation on behalf of Tatiana’s extended family.

“Our beautiful Tatiana passed away this morning. She will always be in our hearts,” the statement read. It was signed by “George, Edwin and Josephine Moran, Ed, Caroline, Jack, Rose and Rory.”

Kerry, 66, shared the same photo on her Instagram Stories, writing a heartfelt message in tribute to her cousin. “Tatiana left our world more joyful, more beautiful, more full of loving kindness,” she wrote. “May we all learn from her extra life.”

Actor Richard Kind also reacted to the post, leaving a broken heart emoji in the comments.

Kerry is the daughter of Robert F. Kennedy and the niece of President John F. Kennedy. JFK was Tatiana’s grandfather, making Kerry her second cousin.

Tatiana’s death comes after she revealed in an essay published by The New Yorker in November 2025 that she had been diagnosed with acute myeloid leukemia. She explained that she learned of the diagnosis while hospitalized after giving birth to her second child.

A journalist by profession, Tatiana shared that she had just welcomed her daughter, Josephine, when doctors discovered the illness. She and her husband, Dr. George Moran—whom she married in 2017 after the two met at Yale University—were already parents to a son, Edwin, born in 2022. Josephine was born on May 25, 2024, at Columbia-Presbyterian Hospital in New York City.

“I did not — could not — believe that they were talking about me,” she wrote of her diagnosis. “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.”

In the same essay, Tatiana reflected on the weight of adding another tragedy to a family marked by profound loss.

“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 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.”

Tatiana’s mother, Caroline Kennedy, was just days away from her sixth birthday when her father, President John F. Kennedy, was assassinated in Dallas on Nov. 22, 1963. Nearly five years later, her uncle Robert F. Kennedy was assassinated in June 1968. Decades afterward, Caroline also lost her only living sibling, John F. Kennedy Jr., who died in a plane crash in 1999 along with his wife, Carolyn Bessette.

Tatiana is remembered by her family and loved ones as a woman of deep compassion, warmth, and grace—qualities Kerry Kennedy said made the world “more joyful” simply by her presence.
