New York — Caroline Kennedy stood with her grandson outside St. Ignatius of Loyola Church on January 5, 2026. She cradled her granddaughter in her arms as family and friends prepared to enter for a private funeral service. The solemn gathering marked the farewell to her daughter, Tatiana Schlossberg, who died at age 35 after a battle with leukemia.

Tatiana, a respected environmental journalist and author, was the daughter of Caroline Kennedy and Edwin Schlossberg. She also was the granddaughter of President John F. Kennedy and Jacqueline Kennedy Onassis.

Tatiana died on December 30, 2025, after a fierce struggle with acute myeloid leukemia, a rare and aggressive blood cancer. Six weeks earlier, she had publicly shared her terminal diagnosis in an essay for The New Yorker, describing how the disease was discovered shortly after the birth of her daughter.

In her essay, Tatiana wrote about her love for her family and the fear of leaving her young children behind. She also detailed months of treatment, including chemotherapy, stem‑cell transplants, and clinical trials.
