Caroline Kennedy's daughter and John F. Kennedy's granddaughter, Tatiana Schlossberg, has died. She was 35 years old. The author and environmental journalist reportedly succumbed to acute myeloid leukemia. The news comes weeks after she revealed her diagnosis in an essay written for The New Yorker in November. Tatiana Schlossberg was born to Caroline Kennedy and Edwin Schlossberg. The pair also shares daughter Rose Schlossberg and son, Jack Schlossberg. Caroline is an author, diplomat, and attorney. She previously worked as the U.S. ambassador to Japan and Australia. She is the only surviving child of the late President and First Lady Jacqueline Kennedy Onassis. Tatiana Schlossberg opens up about cancer diagnosis, gushes over her family for their support: Read more View this post on Instagram Instagram PostAs of this writing, Caroline Kennedy has yet to address a statement about her daughter's demise, though she and the rest of her family did issue a joint statement on the Instagram page of the JFK Library Foundation confirming the same. "Our beautiful Tatiana passed away this morning. She will always be in our hearts," the post reads. It was signed by "George, Edwin and Josephine Moran," and "Ed, Caroline, Jack, Rose and Rory." Just last month, after Tatiana Schlossberg released her essay, her cousin, Kerry Kennedy, expressed pride over her for going public with the news. “I think she is so courageous to put herself out [there] in such a public way and all of us are holding her close to our hearts and holding Caroline [Kennedy] especially as well,” Kerry, 66, told Us Weekly. In her essay, Tatiana Schlossberg recounted the moment she had learned of her diagnosis, just after she had given birth to her second child. “I did not — could not — believe that they were talking about me. 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. “I had a son whom I loved more than anything and a newborn I needed to take care of.” The late author shared son Edwin, 3, and a 19-month-old daughter, whose name is still unclear, with her husband, George Moran. The pair reportedly tied the knot in 2019. “My first thought was that my kids, whose faces live permanently on the inside of my eyelids, wouldn’t remember me,” she shared. “My son might have a few memories, but he’ll probably start confusing them with pictures he sees or stories he hears. I didn’t ever really get to take care of my daughter — I couldn’t change her diaper or give her a bath or feed her, all because of the risk of infection after my transplants. I was gone for almost half of her first year of life. I don’t know who, really, she thinks I am, and whether she will feel or remember, when I am gone, that I am her mother.”After her essay, her brother, Jack, also voiced his support for his sister. He shared a screenshot of her essay on his Instagram Stories with the following caption: “Life is short — let it rip." Tatiana Schlossberg also gushed over her family for their unending support in her piece for the New Yorker, titled "A Battle With My Blood": “My parents and my brother and sister, too, have been raising my children and sitting in my various hospital rooms almost every day for the last year and a half,” she said. “They have 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.” Stay tuned to SoapCentral for more.
