Jack Schlossberg Reacts to Sister Tatiana’s Terminal Cancer Diagnosis

by

Jack Schlossberg is standing by his family.

Following his sister Tatiana Schlossberg’s announcement that she has terminal cancer, Caroline Kennedy and Edwin Schlossberg’s son publicly shared his support online.

On November 22nd, Jack, 32, shared parts of an essay by Tatiana on his Instagram Stories. The essay, published in The New Yorker, described her diagnosis with acute myeloid leukemia after she and her husband, George Moran, welcomed their second child in May 2024.

The candidate for Congress, who announced his campaign earlier this month, shared a personal message on social media. He posted a photo of a concrete road, followed by a picture of a blue sky, with the caption, “Life is short—let it rip.”

Tatiana, who shares 3-year-old Edwin Jr. with George, wrote about her battle with a rare bone cancer. She underwent extensive treatments, including chemotherapy, a bone-marrow transplant, and a new type of therapy called CAR-T-cell therapy. Despite these efforts, doctors estimate she has about a year to live.

After receiving her diagnosis, the 35-year-old thought about the incredible support she’s received from her family, including Jack and her sister Rose Schlossberg, throughout her battle with cancer.

She shared that her parents, brother, and sister have been incredibly supportive, caring for her children and spending almost every day with her in the hospital over the past year and a half. They’ve been a constant source of strength, quietly bearing their own pain to shield her from it, which she deeply appreciates even though she’s aware of their struggles.

The journalist also fondly remembered her husband, whom she married in 2017, sharing that he was incredibly supportive and always went above and beyond for her.

I truly believe everyone deserves happiness, but honestly, if you have the chance to marry a doctor, do it! I say this because losing my own husband has been devastating. He was just… perfect. Kind, hilarious, brilliant, and incredibly handsome. I feel like I’ve lost the best life imaginable, and it’s just so incredibly sad to think I won’t get to share it with him anymore.

For now, Tatiana wrote that her focus is on her kids.

I mostly focus on enjoying time with my loved ones now,” she said. “But it’s surprisingly difficult to stay focused on the present moment, so I allow myself to remember the past when it surfaces, and also let those memories fade when they need to.

Keep reading for a closer look at the Kennedy family tree.

Joseph Patrick “Joe” Kennedy married Rose Elizabeth Fitzgerald on Oct. 7, 1914.

By 1932, Joseph and Rose Kennedy had nine children: Joseph P. Kennedy Jr., John F. Kennedy, Rosemary Kennedy, Kathleen Kennedy, Eunice Kennedy, Patricia Kennedy, Robert F. Kennedy, Jean Kennedy, and Edward Kennedy.

Born July 25, 1915, Joe Jr. was going to be president, as far as his father was concerned.

He attended the 1940 Democratic National Convention and intended to run for Congress after his service in the Navy. Tragically, the 29-year-old and his co-pilot, Wilford John Willy, died on August 12, 1944. They were carrying explosives on a bombing mission as part of Operation Aphrodite when the explosives unexpectedly detonated.

The pilots’ bodies were never found, and they are remembered on the Wall of the Missing at the Cambridge American Cemetery, which honors those who died in World War II.

John, born on May 29, 1917, began his political career in Congress before becoming a U.S. Senator and eventually winning the presidency in 1960.

He married Jacqueline Bouvier on September 12, 1953. They had two children: Caroline Kennedy, born November 27, 1957, and John F. Kennedy Jr., born November 25, 1960.

The couple tragically lost a daughter, Arabella, who was stillborn in 1956. Several years later, their son, Patrick, was born prematurely on August 7, 1963, but sadly lived for only 39 hours.

JFK was assassinated on Nov. 22, 1963, one of the defining events of the 20th century.

I’ve always admired Caroline Kennedy! She’s had such a distinguished career, serving as the U.S. ambassador to both Japan during President Obama’s time in office and then to Australia under President Biden. It’s wonderful to remember that she married Edwin “Ed” Schlossberg way back in 1986 – they’ve built a lovely life together.

Caroline and Edwin Schlossberg have three children: Rose, born June 25, 1988; Tatiana, born May 5, 1990; and their son, John (known as Jack), born January 19, 1993.

TV producer Rose went to Harvard like her mom and married restaurateur Rory McAuliffe in 2022.

Tatiana, a journalist, later discovered that a 2014 article she wrote for the New York Times about a bear found dead in Central Park unexpectedly involved her cousin, RFK Jr. She graduated from Yale and married her college sweetheart, George Moran, in 2017. They have two children: a son, Edwin Jr., born in 2022, and a daughter born in 2024.

 

In a November 2025 essay for The New Yorker, Tatiana revealed she had been diagnosed with acute myeloid leukemia, a rare and terminal blood cancer, according to her doctors.

Jack, a graduate of both Yale and Harvard’s joint JD/MBA program, gained attention for his lively presence on social media. He recently spoke at the 2024 Democratic National Convention and reported on the latest presidential election for Vogue magazine.

In a 2024 interview with Vogue, he shared that he’s motivated by his family’s history of helping others. He feels a strong sense of responsibility to continue that tradition and wants to find his own way to make a difference, focusing on both long-term goals and immediate positive change.

 

Before marrying Carolyn Bessette, a publicist for Calvin Klein, on September 21, 1996, the former first son was widely considered one of the most desirable bachelors in the world. He had even been named People magazine’s Sexiest Man Alive in 1988.

John F. Kennedy Jr. tragically died in a plane crash on July 16, 1999, mirroring his father’s early death. He was with his wife, Carolyn, and her sister, Lauren Bessette, at the time, bringing immense grief to his family.

Rosemary (at right, with sister Kathleen and mom Rose) was born Sept. 13, 1918.

Rosemary went to a boarding school for students who struggled with learning. However, she also had behavioral problems, and at age 23, her father authorized a prefrontal lobotomy in an attempt to address them.

Rosemary underwent an experimental treatment meant to address mental illness, and while her father, Joe, had hoped for a recovery, the procedure left her severely disabled. She spent the remainder of her life, until January 7, 2005, living in an institution.

Rose later told historian Doris Kearns Goodwin that she’d always thought her daughter could have had a more relaxed life within the Kennedy family. However, everything changed—and was lost—in just a few minutes.

Born Feb. 20, 1920, Kathleen got a kick out of life, hence her jaunty nickname.

She married William Cavendish, the Marquess of Hartington, in a London ceremony on May 6, 1944. Her mother disapproved of the match because he wasn’t Catholic, so only her brother, Joe Jr., attended the wedding.

A month later, William, a major in the British Army, was killed by a sniper in Belgium.

She stayed in England and became romantically involved with William Wentworth-Fitzwilliam, the 8th Earl Fitzwilliam, who was married at the time. Tragically, both of them died in a plane crash on May 13, 1948, while traveling to the French Riviera, before he could finalize a divorce.

Eunice was born July 10, 1921.

Eunice Kennedy Shriver, a passionate advocate for people with intellectual disabilities and the creator of the Special Olympics, married Robert Sargent Shriver Jr. on May 23, 1953.

They had five children: Robert “Bobby” Shriver III (born April 28, 1954), Maria Shriver (born November 6, 1955), Timothy (born August 29, 1959), Mark (born February 17, 1964), and Anthony (born July 20, 1965).

Maria Shriver married Arnold Schwarzenegger on April 26, 1986, at the Kennedy family estate in Hyannis Port, Massachusetts.

Arnold Schwarzenegger and Maria Shriver served as California’s governor and first lady from November 2003 to January 2011. Their marriage ended shortly after it was revealed that Schwarzenegger had fathered a son, Joseph Baena, with a member of their household staff.

Eunice passed away at the age of 88, leaving behind 19 grandchildren. This included Maria Shriver’s four children from her previous marriage: Katherine (born December 13, 1989), Patrick (born September 18, 1993), Christina (born July 23, 1991), and Christopher (born September 27, 1997).

Katherine married Chris Pratt on June 8, 2019, and they have three children together: Lyla (born August 6, 2020), Eloise (born May 21, 2022), and Ford (born November 8, 2024). Chris also has a son, Jack (born August 17, 2012), from his previous marriage to Anna Faris.

Patricia, who was born on May 6, 1924, became connected to the famous Rat Pack when she married Peter Lawford on April 24, 1954.

She and her British actor husband had four children: Christopher Lawford (born 1955), Sydney Maleia Lawford (1956), Victoria Francis Lawford (1958), and Robin Elizabeth Lawford, before their marriage ended in divorce in 1966.

Peter, who passed away in 1984, was a close friend to his brother-in-law, John F. Kennedy. He’s widely believed to be the one who first introduced JFK to Marilyn Monroe when she visited the home of his sister and her husband in Malibu.

Patricia died in 2006. Her son, Christopher, who had been married three times, passed away in 2018 after a heart attack.

The son known familiarly to the whole country as Bobby Kennedy married Ethel Skakel on June 17, 1950.

They had a large family, with eleven children named Kathleen, Joseph II, Robert Jr., David, Courtney, Michael, Kerry, Christopher, Maxwell, Douglas, and Rory.

Ethel was pregnant with Rory when Bobby was tragically killed by a gunshot on June 6, 1968, just after winning the California Democratic primary election.

It still breaks my heart thinking about David Kennedy. He was so young, only 28 when he tragically passed away in 1984. And then, years later, Michael… it was just awful. A ski accident in Aspen, on New Year’s Eve, 1997. They said he was even tossing a football around with family right before it happened. He was only 37 and left behind three kids with his wife, Victoria Gifford. It’s just… devastating. I can’t believe both of them are gone.

Ethel Kennedy experienced the loss of her husband when her oldest child was just 16 years old, but she later became a grandmother to 34 grandchildren. Sadly, she has lost two of them: 22-year-old Saoirse Hill, who died in 2019 from an accidental drug overdose, and her 40-year-old granddaughter, Maeve Kennedy McKean, who died in a canoeing accident in 2020. Saoirse was the daughter of Courtney Hill and Paul Hill, while Maeve was the daughter of Kathleen Kennedy Townsend and David Townsend.

RFK Jr., born Jan. 17, 1954, is a thrice-married father of six.

He and his first wife, Emily Black, have two children: Robert Francis “Bobby” Kennedy III, born in 1984, and Kathleen “Kick” Kennedy, born in 1988.

They divorced in 1994 after 12 years of marriage. 

RFK III has been married to CIA analyst turned author and TV host Amaryllis Fox since 2017.

The couple have three children: a daughter named Bobby, born in January 2019, and a son named Cassius Watts Thoreau Kennedy, born in August 2021. They also raise Amaryllis’ daughter, Zoë, from a previous relationship.

 

I’ve always loved how this Stanford alum put it back in 2012 when talking to Town & Country: life isn’t about anything but the experiences you collect—the good ones and the tough ones alike. Honestly, I think the more you experience, the richer your life becomes.

As a lifestyle observer, I noticed something interesting in August 2024. After Jennifer Lopez filed for divorce from Ben Affleck, a name you might not expect started trending: Kick Kennedy. Apparently, even just a casual acquaintance with Ben Affleck was enough to put her in the spotlight – it really shows how connected we all are these days!

A representative for Ben Affleck immediately denied rumors of a romantic relationship, telling TopMob News that reports about him and Kick are false.

So nothing about being a Kennedy had really changed in a decade. Or a century.

I often get asked what it’s like to be a Kennedy,” she shared with Town & Country. “Honestly, I don’t really know. It’s strange to see my face or name in the tabloids – it makes me anxious. It feels like I’m reading about someone else, not the real me.”

Despite never meeting her, she felt a connection to the great-aunt she was named after, who had passed away long before her father was even born.

“It’s funny how similar we are,” Kick mused. “She was fun and social and a performer in many ways.”

Robert F. Kennedy Jr. married Mary Richardson in 1994, and they had four children together: Conor Richardson Kennedy (born July 25, 1994), Kyra LeMoyne Kennedy (born August 22, 1995), William Finbar “Finn” Kennedy (born November 8, 1997), and Aidan Caohman Vieques Kennedy (born July 13, 2001).

The couple were legally separated when Mary died by suicide in 2012.

Father and sons: Conor, Aidan and RFK III.

Despite achieving sudden fame at 18 as a Harvard student – and famously introducing Taylor Swift to his family – Conor has generally kept a relatively private life, even with his activism and other notable activities.

I remember when they first got together – it felt like a fairytale! Sadly, it wasn’t meant to be, and things ended after just a few months. But honestly, even though it didn’t last, it was still amazing to watch. Conor really went on to do great things, graduating from Georgetown Law – he’s incredibly accomplished. Of course, back then, it was all anyone could talk about – they made headlines, that’s for sure!

“Taylor Swift’s ex Conor Kennedy” is now engaged to singer Giulia Be.

Kyra, a regular among the high-fashion set, lives in Milan.

In a video released on August 27, 2024, in collaboration with Elle and Bvlgari, she revealed she’s developing a project to honor her mother’s memory.

She wonders if she’s fundamentally changed as a person. “Yes, absolutely,” she replies. “I was one way as a child, but I completely transformed when I grew into adulthood.”

RFK Jr. married Curb Your Enthusiasm star Cheryl Hines in 2014.

The actress shares daughter Catherine Young (born March 8, 2004) with ex-husband Paul Young. 

In a 2018 Instagram post for Father’s Day, Kick thanked her dad for giving her her many siblings, jokingly calling them “wacky.”

Ethel Kennedy and Robert F. Kennedy Jr.’s seventh child has three daughters with her former husband, Andrew Cuomo: twins Mariah Kennedy-Cuomo and Cara Kennedy-Cuomo (born in 1995), and Michaela Kennedy-Cuomo (born in 1997).

Kerry and Andrew married in 1990, but their relationship ended after a separation in 2003 and a divorce finalized in 2005. Andrew served as governor of New York from 2011 to 2021.

Born on February 20, 1928, as the eighth of nine children to Joe and Rose, Jean Kennedy founded the VSA Kennedy Arts Center and later served as the U.S. Ambassador to Ireland under President Clinton.

She married Stephen Edward Smith, who worked as a strategist for John F. Kennedy’s presidential campaign, on May 19, 1956. Together, they had four children: sons Stephen Smith Jr. and William Smith, and daughters Amanda Smith and Kym Smith.

Jean died June 17, 2020, having outlived all of her siblings.

Senator Ted Kennedy had three children with his first wife, Joan Bennett: Kara Kennedy (born February 27, 1960), Edward Kennedy Jr. (born September 26, 1961), and Patrick Kennedy II (born July 14, 1967).

He and Joan divorced in 1982 after 24 years of marriage and he wed Victoria Reggie in 1992.

Kara passed away from a heart attack on September 16, 2011, two years after losing her father. Joan died on October 8, 2025.
