She was the world’s most famous toddler. A "poor little rich girl" before she could even spell her own name. If you grew up reading the tabloids in the late eighties, you remember the grainy photos of a blonde child being whisked across tarmacs or sitting on the lap of a woman who looked perpetually exhausted by the weight of her own jewelry. That child was Athina Onassis, the only surviving daughter of Christina Onassis.
The Onassis name isn’t just a name. It’s a heavy, gold-plated anchor. For Athina, it meant inheriting a shipping empire, private islands, and a legacy defined by "The Onassis Curse." People act like she’s a character in a Greek tragedy because, frankly, her family history reads like one. Her grandfather, Aristotle Onassis, was arguably the most famous man on earth. Her mother, Christina, died in a bathtub in Argentina when Athina was only three years old.
Life didn't start easy, despite the billions.
The Inheritance and the "Curse"
Most people assume being the daughter of Christina Onassis meant waking up in a bed of cash and staying there. Not quite. When Christina died in 1988, Athina became the sole heir to a fortune that experts at the time estimated between $500 million and several billion dollars. It included the legendary Olympic Maritime empire and Skorpios, the private island where her grandfather married Jackie Kennedy.
But there was a catch. Actually, several catches.
Christina didn’t trust Athina’s father, Thierry Roussel. She set up a board of administrators—the "Greybeards"—to manage the money until Athina turned eighteen. This created a decade-long legal war. On one side, you had a French playboy father. On the other, the fierce Greek loyalists of the Onassis Foundation. Athina was stuck in the middle, growing up in a quiet village in Switzerland, trying to be a normal kid while lawyers argued over her piggy bank in courtrooms across Europe.
It’s kinda wild when you think about it. She was living this suburban Swiss life, going to school and riding horses, while being the subject of international litigation. She didn't even speak Greek fluently back then. That really rubbed the Greek public the wrong way. They wanted her to be a "Hellenic Princess," but she just wanted to be a teenager who liked animals.

Why She Walked Away From the Spotlight
Athina Onassis is the anti-celebrity. You won’t find her on a reality show. She doesn't have a verified Instagram where she’s hawking skincare. Honestly, she seems to hate the fame that killed her mother. Christina Onassis lived for the cameras and the jet-set parties, and it arguably led to her downward spiral. Athina saw that. She learned from it.
She spent most of her adulthood trying to disappear.
The most shocking thing she ever did wasn't a scandal. It was selling Skorpios. For decades, that island was the soul of the Onassis family. It's where Aristotle, Alexander, and Christina are buried. When Athina sold the lease to a Russian billionaire’s daughter in 2013, the Greek media went into a full-blown meltdown. They saw it as a betrayal of her bloodline. But for Athina, it was probably just property. Expensive, haunted property.
She also stayed away from the Onassis Foundation. She never became the president of the board, a role many expected her to take when she hit thirty. Instead, she chose the stables.
The Equestrian Life and the Doda Era
Horses were her escape. They don't care about your bank balance or your tragic backstory.
In the early 2000s, Athina moved to Brazil. She fell for Álvaro de Miranda Neto, a Brazilian Olympic show jumper known as "Doda." They married in 2005. For a while, it looked like she’d finally beaten the curse. She looked happy. She was competing in high-level show jumping events under the name Athina Onassis de Miranda. She poured millions into top-tier horses and training facilities.

But the Onassis luck is a stubborn thing.
The marriage ended in 2016 amid rumors of infidelity on his part. It wasn't a quiet divorce. There were disputes over ownership of horses and money, mirroring the legal battles of her childhood. By the time it was finalized, Athina had retreated even further from the public eye. She dropped the "de Miranda" and went back to being Athina Onassis, but the scars were visible to anyone paying attention to the equestrian circuit.
What Most People Get Wrong About Her Wealth
There’s a huge misconception that Athina is still the "richest girl in the world." She’s still incredibly wealthy, don’t get me wrong. But she isn't the multi-billionaire the press once claimed.
Between the massive divorce settlement, the sale of assets like the family’s Avenue Foch apartment in Paris, and the staggering costs of maintaining an elite show-jumping stable, her net worth has likely shifted. Some estimates now put her at the high hundreds of millions rather than the multi-billion mark. Still, she’s doing fine. But the idea that she’s sitting on top of an untouched mountain of Aristotle’s gold is a myth.
She has spent her life liquidating the past to fund a private present.
The Legacy of the Daughter of Christina Onassis
Today, Athina is a ghost in the world of high society. She shows up at the Longines Global Champions Tour, she rides, she leaves. She doesn't give interviews. She doesn't write memoirs. There’s a certain dignity in that, isn't there? In a world where everyone is oversharing, the daughter of Christina Onassis chose silence.

She is the last of the line. There are no other Onassis heirs. When she's gone, the name—in a direct sense—fades out.
If you're looking for lessons from her life, it's basically this: you can't choose your ancestors, but you can choose how much space they take up in your head. Athina inherited a tragedy and turned it into a quiet, horse-centric life. That’s probably the biggest win she could have hoped for.
Understanding the Onassis Timeline

Actionable Takeaways for Following the Story
If you want to keep up with what Athina is actually doing today, stop looking at celebrity gossip sites. They just recycle old photos from 2008. Instead, follow the Longines Global Champions Tour results. That is the only place she appears with any regularity.
Watch the business moves of the Onassis Foundation (Onassis Stegi). They are the ones actually carrying on the "Greek" part of the legacy through arts and culture, while Athina lives her life as a private citizen in Europe.
Finally, recognize the difference between "The Onassis Fortune" (the foundation) and "Athina’s Fortune" (her personal inheritance). They have been legally and operationally separate for decades. Understanding that distinction is key to seeing how she successfully detached herself from a family business she never asked to run.
