Elon Musk Family Tree: Meet the Women Behind His 14 Kids

From Tesla to toddlers, here’s a look at Elon Musk’s growing family of 14 children and the four women who have shaped his journey into fatherhood.

Let’s talk about the man who’s not just revolutionizing space travel and electric cars – he’s also building quite a remarkable family tree. Elon Musk, the mastermind behind Tesla and SpaceX, has been making headlines lately for something completely different from his usual tech ventures: his growing family.

With reportedly 14 children from four different women, Musk’s personal life is as fascinating as his business endeavors.

From his first marriage to a Canadian author to recent claims by a conservative influencer, the billionaire’s family story reads like a modern-day saga that keeps everyone guessing what might happen next. Ready to dive into this intriguing family constellation? Let’s meet the women who’ve shaped Musk’s journey into fatherhood.

Justine Wilson: The first wife and mother of six

Remember the saying about first loves leaving lasting impressions? Well, Elon Musk‘s first marriage to Canadian author Justine Wilson certainly left its mark on his life. Their love story began in the halls of Queen’s University in Ontario, where Justine, then an aspiring writer, caught the eye of the ambitious young Musk. After graduation, they reconnected and tied the knot in January 2000, with dreams of building both their careers and a family.

Justine, now a successful author, known for her contemporary fantasy novels, has been remarkably open about their marriage in her writing and interviews. She’s described their relationship as one that started with genuine romance but gradually became overshadowed by Musk’s growing business empire and strong personality.

Their first pregnancy brought immense joy with the birth of Nevada Alexander in 2002, only to end in heartbreak when he passed away at just 10 weeks old from SIDS. The loss deeply affected both parents and would influence their future family planning decisions.

Determined to build their family, the couple turned to IVF, welcoming twins Griffin and Xavier (now Vivian Jenna Wilson) in 2004. But here’s where the story takes an unexpected turn – Vivian has since charted her own course, legally changing her name and gender, and making it crystal clear she wants nothing to do with her famous father.

Her words pack quite a punch:

I no longer live with or wish to be related to my biological father in any way, shape or form.

She’s described Musk as “cold, quick to anger” and “uncaring and narcissistic,” particularly pointing to his rejection of her transgender identity.

The couple went on to have triplets – Kai, Saxon, and Damian – through IVF in 2006. Despite having five children together, their marriage began showing cracks. Justine has written about feeling more like an “employee“ than a wife, describing how Musk’s growing success and dominant personality gradually overshadowed their relationship.

The marriage ended in divorce in 2008, but they’ve maintained a co-parenting relationship for their five living children. Justine has primary custody, with the children splitting their time between both parents. She’s since become an advocate for maintaining individual identity within marriages and has written extensively about the challenges of co-parenting with a high-profile ex-spouse.

Grimes: A complex co-parenting relationship

Just when you thought celebrity relationships couldn’t get more interesting, enter Claire Boucher, better known to the world as Grimes. The Canadian musician and visual artist first connected with Musk over artificial intelligence jokes on Twitter in 2018 – talk about a modern meet-cute!

Their relationship quickly became a favorite topic for tech and entertainment media alike, bringing together Silicon Valley and avant-garde art in a way that had everyone talking.

Their unique dynamic was reflected in their approach to parenthood, starting with their first child’s notably distinctive name. X Æ A-12 arrived in May 2020, though they had to modify it to X Æ A-Xii to comply with California naming laws (because even billionaires have to follow the rules!).

The parents even had to explain the pronunciation – it’s “X A.I. Archangel” if you’re wondering – and the meaning behind each character, which includes references to artificial intelligence and their favorite aircraft.

Their family grew with Exa Dark Sideræl (nicknamed “Y”) who arrived via surrogate in December 2021. The name choice was just as meaningful: Exa refers to supercomputing, Dark represents “the unknown,” and Sideræl (pronounced “sigh-deer-ee-el”) is an elven spelling of sidereal, which means “the true time of the universe.”

Their third child, Techno “Tau” Mechanicus, joined the family in 2022, completing their trio of uniquely named offspring.

But here’s where things get complicated. Despite their shared love of futuristic names, electronic music, and philosophical discussions about simulation theory, Grimes and Musk’s relationship hit some serious turbulence. Their on-again-off-again dynamic played out publicly on social media, with Grimes occasionally sharing glimpses of their co-parenting challenges.

By 2024, they were engaged in a legal battle over parental rights for all three kids. Grimes didn’t hold back about the emotional rollercoaster, sharing on X:

While Musk seems to have a special bond with X, often bringing him to public events and SpaceX facilities, the details of their custody arrangement are kept under wraps – proving that even the most public figures can keep some things private when they really want to.

Shivon Zilis: Three children together

Talk about keeping things in the family business! Shivon Zilis, a prominent figure in the artificial intelligence world and an executive at Musk’s brain-chip company Neuralink, brings an impressive resume to the co-parenting table.

With degrees from Yale and experience at Bloomberg Beta and OpenAI, Zilis has been named on Forbes’ 30 Under 30 list and is known for her expertise in emerging technologies. She first crossed paths with Musk in the AI development sphere, where their shared interest in advancing human potential through technology created a strong professional connection.

Their relationship took a more personal turn, leading to the birth of twins, Strider and Azure, through IVF in 2021. The names seem to reflect both parents’ interests – Strider potentially referencing the sci-fi/fantasy realm (think Aragorn from Lord of the Rings) while Azure hints at technological connections (like Microsoft’s cloud platform).

The twins were born just weeks before Musk’s second child with Grimes, making for quite an eventful year in the Musk family timeline.

And just when everyone thought that was it, they welcomed a third child via surrogate in 2024, though they’re keeping those details closer to the vest. Unlike some of Musk’s other co-parenting situations, this one seems to be smooth sailing.

Sources say he maintains a positive relationship with Zilis and their three children, with both parents taking a more private approach to their family life.

Their successful co-parenting arrangement might be attributed to their shared intellectual interests and commitment to privacy, proving that sometimes, workplace relationships can have a happy ending (though maybe don’t try this at your own office!).

What makes their dynamic particularly interesting is how they’ve managed to balance their professional collaboration at Neuralink with their personal life. Zilis continues to serve as a director at the company while co-parenting their children, demonstrating a modern approach to work-life integration that’s becoming increasingly common in tech circles.

Ashley St Clair: The latest claims

Just when we thought we had the complete picture of Musk’s family tree, February 2025 brought us a plot twist nobody saw coming. Ashley St. Clair, a conservative political commentator, burst onto the scene with some jaw-dropping news that had everyone talking.

So who exactly is Ashley? She’s the 26-year-old behind the children’s book Elephants Are Not Birds who’s built quite the following for her outspoken conservative views. With over 1.1 million followers on X, she’s definitely not someone who flies under the radar in political circles.

You might have spotted her at Donald Trump‘s election night event at Mar-a-Lago or posing for photos with GOP spokeswoman Elizabeth Pipko and Congressman Matt Gaetz’s wife, Ginger.

After making a nostalgic return to social media by sharing a throwback photo from Trump’s 2017 inauguration, St Clair dropped a bombshell: she claimed she had welcomed Musk’s 13th child in late 2024.

Talk about keeping a secret! She’d managed to stay mum about it for five months, hoping to protect her baby’s privacy. But as these things often go, tabloids caught wind of the story, and she decided to get ahead of the narrative.

Her representatives have been busy, stating that she’s been working on hammering out a parenting agreement with Musk “for some time.” And Musk’s response? Well, it was characteristically brief. When someone on X claimed that,

the tech mogul replied with a simple “Woah“ – leaving everyone to read between the lines. The drama didn’t stop there, though. By February 2025, what started as social media whispers exploded into full-blown legal action. St. Clair filed both paternity and custody petitions against the 53-year-old tech mogul.

According to her court filings (which, let’s be honest, make for quite the read), she and Elon began their romance around May 2023. Fast forward to January 2024, and they allegedly conceived their child during a getaway to the island of St. Barts – pretty fancy, right?

The baby boy, who goes by the initials R.S.C. in court documents, was born in September 2024. And here’s where things get even more interesting: St. Clair claims Musk has only met their son three times since his birth.

The first meeting? A two-hour visit in New York City on September 21, followed by a one-hour encore the next day. The third and reportedly last meeting happened in Austin, Texas, on November 30 – and lasted just half an hour. Not exactly what you’d call hands-on parenting!

St. Clair isn’t holding back in her legal filings either. She’s gunning for sole legal and physical custody, basically saying Musk has shown zero interest in being a dad to their little one. According to her, she’s been flying solo when it comes to making decisions for their baby.

Her team has been pretty blunt about the whole situation. They told PEOPLE:

This has never been about money for Ashley. This is about protecting the best interests of Ashley and Elon’s child from a man who can’t be counted on to even communicate, much less act consistently in the role of a father.

Ouch! They also claimed they tried working things out with Musk behind the scenes, but he “refused all conversations.” Not a great look for the billionaire, if true.

In a particularly spicy twist, St. Clair included text screenshots in her filing that allegedly show Musk acknowledging he’s the father. And get this – she claims he texted her in November 2024 (as presented in DailyMail) saying,

I want to knock you up again,

and followed up three months later with:

Well, we do have a legion of kids to make.

Sounds like somebody was thinking about building their own SpaceX workforce!

Musk hasn’t directly responded to St. Clair’s specific claims, though he did fire back at a YouTuber who criticized his parenting on X.

Meanwhile, St. Clair is reportedly living the high life in a luxury apartment near New York City’s City Hall, with rent estimated between $12,000 and $15,000 per month. According to neighbors, she mostly keeps to herself and has even added her own security camera despite the building’s already tight security. Clearly, privacy is a priority for the new mom.

As this saga continues to unfold, one thing’s certain – Musk’s family tree just keeps getting more complex! With multiple children now with four different women, Elon might need to start using one of his famous spreadsheets just to keep track. We’ll be watching closely to see how this latest chapter develops in the ever-expanding Musk family drama.

Just when the dust was beginning to settle on the Ashley St. Clair revelations, Elon Musk’s family tree sprouted yet another branch! In March 2025, Neuralink executive Shivon Zilis announced the arrival of her fourth child with Musk – bringing his total to a whopping 14 kids.

The announcement came in classic tech-world fashion via social media. Zilis posted on X:

Musk’s response? A simple heart emoji – apparently the billionaire’s preferred method of confirming parenthood these days!

The timing raised more than a few eyebrows, coming just two weeks after Ashley St. Clair’s bombshell claims about Musk fathering her child. Talk about complicated family dynamics!

Seldon Lycurgus (and can we just take a moment to appreciate Musk’s continued tradition of unique baby names?) joins his siblings Strider and Azure, twins born in 2021, and sister Arcadia, who arrived in 2024. The names sound like they could be straight out of a sci-fi novel – which, knowing Musk’s interests, might be exactly the point!

What makes this latest addition particularly interesting is his multicultural heritage. While Zilis maintains a relatively private profile compared to some of Musk’s other co-parents, we do know she hails from Ontario, Canada, and has a fascinating background. Her mother is of Punjabi descent, while her father is Caucasian Canadian, giving little Seldon a connection to Indian roots.

Unlike the drama surrounding some of Musk’s other family announcements, the relationship between the Tesla CEO and the Neuralink executive appears to be relatively drama-free – at least publicly. They’ve managed to build their family of four children while maintaining professional connections through Musk’s brain-computer interface company.

The modern family dynamic

If there’s one thing Musk’s family situation proves, it’s that modern families come in all shapes and sizes. The tech mogul has been pretty vocal about his views on population, even tweeting in 2022:

Well, he’s certainly walking the talk!

His approach to family life reads like a case study in modern parenting – multiple co-parenting relationships, varying levels of involvement with different children, and the kind of complex dynamics that would make a family therapist’s head spin.

While some relationships, like his connection with Zilis and her children, seem to be working smoothly, others – like his estrangement from Vivian and the custody battles with Grimes – show that even billions in the bank can’t guarantee smooth sailing in the parenting department.

As this unique family constellation continues to evolve, it stands as a fascinating example of how traditional family structures are being redefined in the 21st century. Whether you’re Team Musk or not, you can’t deny that his family story makes for one incredibly interesting modern saga.
