When you talk about the golden age of the "Jet Set," one name usually floats to the surface like a diamond in a glass of champagne: Athina Mary "Tina" Livanos. Most people know her as the woman caught between the two most powerful shipping magnates in history. Honestly, her life felt less like a biography and more like a high-stakes chess match played with oil tankers and private islands.
She was the daughter of Stavros Livanos, a man who basically owned the Greek merchant navy. Tina was the ultimate "it girl" before the term was even a thing. But if you look at the Tina Onassis Niarchos spouse timeline, it’s not just a list of names. It’s a map of the most intense corporate and personal rivalries of the 20th century.
The First Marriage: Aristotle Onassis and the 17-Year-Old Bride
In 1946, Tina was only 17. Aristotle Onassis, the legendary "Ari," was 40. He wasn't exactly the "old money" type that Tina’s father liked, but he was persistent. Some say he pursued her for three years, stalking her across continents until her father finally gave in.
It wasn't just love. It was business. By marrying Tina, Onassis got a VIP pass into the inner circle of Greek shipping. He even named his famous yacht—the one with the bar stools made of whale foreskin—the Christina O after their daughter.
They had two kids together: Alexander and Christina. For a while, they were the most photographed couple in the world. But the glamour was thin. Ari was a notorious womanizer. Tina reportedly once walked in on him with a friend of hers at their home in the south of France. Kinda messy, right?
The final straw wasn't just any affair. It was the public, high-octane romance between Onassis and the opera singer Maria Callas. Tina filed for divorce in 1960 on the grounds of "mental cruelty." She didn't want the spotlight; she wanted out.

The Unexpected Pivot: The Duke of Marlborough
After the chaos of Onassis, Tina did something nobody expected. She went for stability. Or at least, British aristocracy’s version of it.
In 1961, she married John Spencer-Churchill, the Marquess of Blandford. He later became the 11th Duke of Marlborough. This moved Tina from the deck of superyachts to the halls of Blenheim Palace. For a decade, she was a Marchioness. She was part of the Churchill family tree.
People thought she’d found her peace. She was wealthy, titled, and far away from the Aegean rivalries. But the marriage didn't last. They divorced in 1971. Some say the "shipping blood" in her veins just didn't mix with the rigid, dusty expectations of the British peerage.
The Shocking Final Act: Stavros Niarchos
This is where the story gets truly wild. If you were writing a soap opera, the writers would say this plot point was "too much."
Stavros Niarchos was Aristotle Onassis's arch-rival. They spent decades trying to outbuild, outbuy, and outmaneuver each other. Niarchos had actually wanted to marry Tina first, back when she was a teenager. When Onassis beat him to it, Niarchos married Tina’s older sister, Eugenia, instead.

In 1970, Eugenia died under very mysterious circumstances on Niarchos’s private island, Spetsopoula. There were bruises. There was an investigation. Ultimately, he was cleared, but the gossip never really died down.
Then, just one year after her sister's death and her own divorce from the Duke, Tina married Stavros Niarchos.
The world was stunned. Why would she marry her sister’s widower? Why would she marry her first husband’s greatest enemy? Some historians think it was a move to protect the family fortune. Others think it was a twisted kind of "first love" finally getting its way. Honestly, it might have just been the only world she felt comfortable in.
The Tragedy of 1974
The marriage to Niarchos was short and shadowed by grief. In 1973, Tina’s son Alexander died in a plane crash. It broke her.
On October 10, 1974, Tina was found dead in a hotel room in Paris. She was only 45. The official cause was an edema, but the rumors of a drug overdose or a "broken heart" have persisted for fifty years. She was buried in Lausanne, Switzerland, alongside her sister.

What We Can Learn from Tina’s Life
Looking back at the Tina Onassis Niarchos spouse history, it’s easy to see her as a pawn in a game between billionaire men. But she was also a woman who tried to define herself outside of those shadows.
If you're researching this for a project or just out of curiosity, here are the takeaways:
- Marriages were tactical: In the 1940s and 50s, these unions were as much about shipping routes as they were about romance.
- The Rivalry was real: The Onassis-Niarchos feud was the defining conflict of her life.
- The "Onassis Curse" is a common trope: While it sounds like a movie plot, the string of early deaths in this family (Alexander, Tina, Christina) is why people still talk about them today.
To get a better sense of the scale of her life, you should look up photos of the Christina O or the interiors of Blenheim Palace. It’s one thing to read about it; it’s another to see the sheer opulence she was trying to navigate.
If you're digging into the genealogy, keep an eye on the name Athina. It repeats through the generations, leading all the way to the current Athina Onassis, Tina's granddaughter, who ended up inheriting what was left of the empire.
Actionable Next Steps
- Cross-reference the timelines: If you are writing a paper, verify the dates of the Onassis-Callas affair versus the divorce filing in Alabama; the "mental cruelty" charge is a specific legal detail often cited in 1960s celebrity divorces.
- Investigate the Niarchos-Livanos connection: Look into the "Spetsopoula incident" involving Eugenia Livanos to understand the heavy baggage Tina carried into her third marriage.
- Study the legacy: Look at how the Onassis Foundation functions today to see how the wealth Tina was once part of is currently distributed.
