For a long time, Jack Schlossberg chose silence. Not because the pain had faded — but because every word felt too heavy to place into the world. As the only grandson of President John F. Kennedy and Jacqueline Kennedy Onassis, Jack grew up under the weight of history. But nothing prepared him for the loss that history would never record: his sister Tatiana.

Jack Schlossberg paid tribute to his late sister, Tatiana Schlossberg, with a touching social media post on the day of her funeral.

The 32-year-old politician took to Instagram on Monday to share several quotes, the first one by his older sister from her 2019 “Incospicious Consumption” book.

“It’s up to us to create a country that takes seriously its obligations to the planet, to each other, and to the people who will be born into a world that looks different than ours has for the last 10,000 years or so,” the quote reads.

“Essentially, what I am describing is hard work with possibly limited success for the rest of your life. But we have to do it, and at least we will have the satisfaction of knowing we made things better.

“…Come on, it will be fun (?).”

He also shared several poems about grief and loss, such as “Crossing the Bar” by Alfred Tennyson, “One Art” by Elizabeth Bishop, “Stopping by the Woods on a Snowy Evening” by Robert Frost and “Just a Memory Away” by Rita S. Beer.

Additionally, Jack included several quotes from former presidents, including Abraham Lincoln and his own grandfather, John F. Kennedy, which read, “There are three things in life which are real: God, human folly and laughter. Since the first two are beyond our comprehension, we must do what we can with the third.”

The author then concluded his post by including a photo of him and Tatiana with their hands over their hearts as they attended what seemed to be a political event. The pic also featured their older sister, Rose, and their dad, Edwin Schlossberg.

Jack’s post was shared the same day he reunited with his family to mourn the loss of Tatiana in a private funeral in the Upper East Side neighborhood of New York City.

We were told that her youngest sibling spoke during the ceremony, which included a Catholic mass.

On Nov. 22, Tatiana revealed she had been diagnosed with acute myeloid leukemia in May 2024 and had only been given a year to live.

She died on Dec. 30, with the JFK Library Foundation, on behalf of Schlossberg’s extended family, announcing via social media, “Our beautiful Tatiana passed away this morning. She will always be in our hearts.” She was 35.

The late journalist is survived by her husband, George Moran, and their two young children, as well as her parents, Caroline Kennedy and Edwin, siblings, Jack and Rose.
