Who Was Tatiana Schlossberg? 5 Things About JFK's Late Granddaughter

Tatiana, one of the late John F. Kennedy and Jacqueline Kennedy Onassis’ grandchildren, disclosed in November 2025 that she had been diagnosed with acute myeloid leukemia after welcoming Josephine in 2024.

“They have supported me steadfastly while I have endured, attempting to conceal their own pain and sadness to shield me from it,” Tatiana recalled of her family’s support in a New Yorker essay. “This has been a profound gift, even though I feel their sorrow each day. … Now I have added a new hardship to [my mother’s] life, to our family’s life, and there’s nothing I can do to prevent it.”

According to Tatiana, her uncommon form of cancer was “unable to be resolved with a standard treatment.” Instead, she underwent chemotherapy and a stem cell transplant.

Maria Shriver, the daughter of JFK’s sister Eunice Kennedy, shared a detailed statement via social media after her cousin’s death.

“I cannot comprehend this. I cannot make any sense of it at all. None. Zero,” Shriver wrote via Instagram. “Tatiana was an exceptional journalist, and she utilized her words to educate others about the planet and how to preserve it. She created a beautiful life with her remarkable husband George, and children Eddie and Josie. She fought with the spirit of a warrior. She was valiant, strong [and] courageous.”

She continued, “My heart has always been with my cousin Caroline ever since we were young children. My entire being is with her now. What a pillar she has been. What a source of love she has been with Ed, Rose, Rory, Jack, George, Eddie, Josie, and all of Tatiana’s cousins and friends and the dedicated doctors who tried so hard.”

Shriver further promised that “those of us remaining will ensure” Tatiana’s children always know “what a beautiful, courageous spirit their mother was and will always be.”
