The Complete List Of Elon Musk’s 14 Children: Names, Ages, And The Four Mothers Of His 'Musk-eteers'

As of late 2024, the world’s most prolific billionaire, Elon Musk, is a father to a staggering 14 children, a number that has been confirmed and expanded upon with several new arrivals throughout the year. The recent births in 2024 have solidified his status as a vocal proponent of increasing birth rates, adding a new layer of complexity to his already unconventional family life. This comprehensive, up-to-the-minute list details every child, their mothers, their unique names, and the latest developments in the Musk family dynasty, including a notable name change and the births of his 12th, 13th, and 14th children. The Tesla and SpaceX CEO has welcomed his children with four different women: his first wife, Canadian author Justine Wilson; musician Grimes (Claire Boucher); Neuralink executive Shivon Zilis; and most recently, conservative influencer Ashley St. Clair. The family tree is a complex weave of unconventional names and high-profile co-parenting arrangements, making it one of the most talked-about topics in the tech and celebrity world.

The Chronological List of Elon Musk’s 14 Children and Their Mothers

Elon Musk's journey into fatherhood began in the early 2000s and has continued through 2024, with each birth drawing significant public attention due to the unique circumstances and the children's distinctive names.

Children with Justine Wilson (6 Children)

Musk's first wife, Justine Wilson, a Canadian author, is the mother of his first six children, all conceived via IVF after the tragic loss of their firstborn.

• 1. Nevada Alexander Musk

Born in 2002. Nevada tragically died of Sudden Infant Death Syndrome (SIDS) at just 10 weeks old. This loss was a pivotal moment in Musk's life, leading him and Wilson to pursue in vitro fertilization (IVF).

• 2. & 3. Griffin Musk and Vivian Jenna Wilson (Twins)

Born in 2004, the twins were the first successful IVF births for the couple. Griffin Musk remains a relatively private figure. Vivian Jenna Wilson, formerly Xavier Alexander Musk, legally changed her name and gender in 2022 to disassociate herself from her father, a highly publicized event that highlighted family tensions.

• 4., 5., & 6. Kai Musk, Saxon Musk, and Damian Musk (Triplets)

Born in 2006, the triplets were the couple's second set of IVF children. They are largely kept out of the public eye, maintaining a low profile despite their father's immense fame.

Children with Grimes (Claire Boucher) (3 Children)

The relationship between Musk and musician Grimes, known for her experimental style, produced some of the most famously unique names in modern celebrity history.

• 7. X Æ A-Xii Musk ('X')

Born in May 2020. Originally named X Æ A-12, the name had to be legally changed to X Æ A-Xii due to California law prohibiting the use of numerals in a name. Grimes has explained the name's meaning: 'X' for the unknown variable, 'Æ' for the elven spelling of AI (artificial intelligence), and 'A-Xii' for the Archangel 12, the precursor to the SR-71 Blackbird aircraft.

• 8. Exa Dark Sideræl Musk ('Y')

Born via surrogate in December 2021. Her name is equally complex: 'Exa' refers to a supercomputing term, 'Dark' represents the unknown, and 'Sideræl' is a 'more elven' spelling of sidereal, meaning pertaining to the stars.

• 9. Tau Techno Mechanicus ('T')

Born around late 2023. This third child's name was revealed in a biography of Musk. 'Tau' is the 19th letter of the Greek alphabet, often associated with the number two times pi (6.28), a constant Musk is known to prefer over pi (3.14). 'Techno Mechanicus' continues the tech-focused naming convention.

The 2024 Babies: New Additions and Expanded Co-Parenting

The year 2024 saw a significant expansion of the Musk family, bringing the total count to 14 children with the addition of three new babies, two with Shivon Zilis and one with a new mother. This rapid expansion highlights Musk’s public commitment to addressing what he calls the "underpopulation crisis."

Children with Shivon Zilis (4 Children)

Shivon Zilis, a top executive at Musk's neurotechnology company Neuralink, first welcomed twins with Musk in 2021. The two most recent additions were born in 2024, cementing her role as the mother of four of his children.

• 10. & 11. Strider and Azure (Twins)

Born in November 2021, just weeks before the birth of Exa Dark Sideræl. The twins were revealed publicly in mid-2022 after court documents for a name change to include Musk's last name surfaced.

• 12. Arcadia

Born in February 2024, Arcadia is the third child Musk and Zilis have welcomed together. The name is reported to be a reference to a mythological and historical region known for its pastoral and utopian beauty.

• 13. Seldon Lycurgus

Born in 2024, Seldon Lycurgus is the fourth child with Zilis and was confirmed in early 2024. The name is believed to be a nod to the science fiction character Hari Seldon from Isaac Asimov's Foundation series, a clear parallel to Musk's passion for space and futurism. Lycurgus is a reference to a legendary Spartan lawgiver, continuing the theme of historical and literary gravitas in the naming choices.

Child with Ashley St. Clair (1 Child)

The most recent addition to the Musk family, and the 14th child overall, was born to conservative influencer and author Ashley St. Clair. This revelation, which came to light in late 2024, introduced a fourth mother into the Musk family dynamic.

• 14. Romulus

Born in September 2024. The name Romulus is instantly recognizable as one of the legendary founders of Rome, alongside his twin brother Remus. This choice further emphasizes the pattern of powerful, historical, and mythological names Musk often favors for his children, reinforcing his vision of building a new dynasty.

The Unconventional Family Dynamics and Legacy

The sheer size and complexity of Elon Musk's family structure are unprecedented in modern corporate history, leading to intense public scrutiny and a deep dive into his personal life. The co-parenting relationships with Justine Wilson, Grimes, Shivon Zilis, and Ashley St. Clair are all managed under different terms, with Musk publicly stating his commitment to providing for all his children. The children's unique names—from the complex, coded nature of X Æ A-Xii and Exa Dark Sideræl to the historical weight of Romulus and Seldon Lycurgus—reflect Musk's own personality and his passion for science fiction, technology, and ancient history. These names, which often serve as powerful LSI keywords, are intentionally chosen to be memorable and to reflect his worldview. The name change of his daughter, Vivian Jenna Wilson, to legally sever her ties with her father, remains one of the most poignant public details of the family's history, highlighting the personal cost of extreme fame and the complicated relationship between the billionaire and some of his offspring. This event, alongside the rapid expansion of the family in 2024, keeps the public conversation about the Musk 'Musk-eteers' constantly evolving and fresh. Musk’s focus on fatherhood and his public encouragement of having more children is a direct extension of his belief that declining birth rates pose one of the greatest threats to human civilization. His personal life, therefore, has become a living, breathing experiment in his ideological beliefs, creating a legacy that is as complex and futuristic as the companies he runs, including Tesla, SpaceX, and The Boring Company.
