The Complete Biography and Family Tree of Elon Musk's 14 Children
The complexity of Elon Musk's family tree is a reflection of his unconventional life. His children, ranging in age from infants to young adults, are shared with four different women: his first wife, Justine Wilson; the musician Grimes; Neuralink executive Shivon Zilis; and conservative author Ashley St. Clair.
Family Unit 1: Justine Wilson (First Wife)
Musk's first wife, Canadian author Justine Wilson, is the mother of his first six children. Their journey began with tragedy but continued with a large family.
- Nevada Alexander Musk: Born in 2002, Nevada tragically passed away from Sudden Infant Death Syndrome (SIDS) at just 10 weeks old.
- The Twins (Born 2004):
- Griffin Musk: One of the twin sons born via IVF.
- Vivian Jenna Wilson: Formerly named Xavier, she legally changed her name in 2022 to reflect her gender identity and to distance herself from her father.
- The Triplets (Born 2006):
- Kai Musk: One of the triplet sons born via IVF.
- Saxon Musk: Another of the triplets.
- Damian Musk: The third of the triplet sons.
The Mother: Justine Wilson. A Canadian author specializing in dark urban fantasy novels, Justine Wilson's works include *BloodAngel* (2005) and *Lord of Bones* (2008). She and Musk were married from 2000 to 2008.
Family Unit 2: Grimes (Musician and Artist)
The children Musk shares with Canadian musician and artist Grimes (Claire Elise Boucher) are famous for their highly unusual, almost cryptographic names that merge technology, science fiction, and mythological references.
- X Æ A-Xii (Born 2020): Originally named X Æ A-12, the name was slightly modified to comply with Californian law, which requires names to use the English alphabet and Arabic numerals. The 'Æ' is pronounced "Ash," and the 'Xii' is Roman numerals for 12. He is often referred to as 'X.'
- Exa Dark Sideræl Musk (Born 2021): Born via surrogate, her name is a combination of terms: 'Exa' refers to a supercomputing term, 'Dark' to the unknown, and 'Sideræl' is a "more elven" spelling of sidereal (relating to distant stars). She is often referred to by the nickname 'Y' or 'Why?'
- Techno Mechanicus (Born 2023): The birth of their third child, nicknamed 'Tau,' was revealed in Walter Isaacson's 2023 biography of Musk. The name continues the theme of technology and science.
The Mother: Grimes. Claire Elise Boucher is a celebrated Canadian singer, songwriter, and record producer known for her experimental, genre-bending music and visual art. Her artistic vision is clearly reflected in the unique names she and Musk chose for their three children.
The Newest Additions: Shivon Zilis and Ashley St. Clair
The most recent and surprising additions to the family tree occurred in late 2024 and early 2025, confirming Musk's total number of children at 14 and his commitment to addressing the "underpopulation crisis."
Family Unit 3: Shivon Zilis (Neuralink Executive)
Shivon Zilis, a high-ranking executive at Musk's AI company Neuralink, has welcomed four children with the billionaire. The most recent additions were announced in early 2025.
- The Twins (Born 2021):
- Strider Musk: One of the boy-girl twins, whose names were revealed in 2022.
- Azure Musk: The other twin, a girl. The names Strider and Azure were reportedly chosen by Musk and Zilis.
- Arcadia (Born 2024): Their third child, a daughter, was born in 2024.
- Seldon Lycurgus (Born February 2025): The birth of their fourth child, a son, was announced by Zilis in February 2025, making him one of the two most recent additions to the family. The name Lycurgus is particularly notable, referencing a legendary Spartan lawgiver.
The Mother: Shivon Zilis. Zilis is a Canadian venture capitalist and a leading figure in the AI world. She is the Director of Operations and Special Projects at Neuralink and was a former board member at OpenAI. Her professional background connects directly to Musk's core business interests.
Family Unit 4: Ashley St. Clair (Conservative Author)
The news of a child with conservative author and political commentator Ashley St. Clair first surfaced in late 2024 and was confirmed in early 2025, adding another layer of complexity to Musk's private life.
- Romulus St. Clair (Born September 2024): The son was born in September 2024, and his name, Romulus, was revealed in early 2025. The name Romulus is a direct reference to the legendary founder of Rome, a name that aligns with Musk's interest in foundational, mythological figures.
The Mother: Ashley St. Clair. St. Clair is an American conservative political commentator, author, and influencer who is known for her work in the political sphere and her large social media following. Her connection with Musk reportedly began through the X platform.
The Fascinating Meaning Behind Elon Musk's Children's Names
The names of Elon Musk's children are far from ordinary, often reflecting a deep interest in science, history, and the future of humanity. These choices offer a unique glimpse into the mind of the billionaire.
The Mythological and Historical Names
Musk and his partners often choose names rooted in history or mythology, suggesting a focus on foundational figures and grand narratives:
- Romulus: Named after the legendary founder of Rome, who, along with his twin brother Remus, was raised by a she-wolf. This name evokes themes of creation and destiny.
- Lycurgus (in Seldon Lycurgus): Lycurgus was the legendary lawgiver of Sparta, credited with establishing the military-focused society of ancient Sparta. This choice highlights a theme of structure and societal foundation.
- Strider and Azure: While less overtly historical, Strider is a term often associated with wandering or a forward path, and Azure refers to the deep blue of the sky or space, fitting for the founder of SpaceX.
The Futuristic and Cryptic Names
The names chosen with Grimes are arguably the most unique, blending technology and abstract concepts:
- X Æ A-Xii (X): The 'X' stands for the "unknown variable." 'Æ' is the elven spelling of "Ai" (love and/or artificial intelligence). 'A-Xii' is a nod to the Lockheed A-12 spy plane, their favorite aircraft.
- Exa Dark Sideræl (Y): 'Exa' is a unit prefix in the International System of Units, representing $10^{18}$. 'Dark' represents the unknown beauty of the universe, and 'Sideræl' refers to the true time of the cosmos.
- Techno Mechanicus (Tau): 'Techno' is self-explanatory, referring to technology, and 'Mechanicus' speaks to the mechanical and engineering world. The nickname 'Tau' is the 19th letter of the Greek alphabet, often used in mathematics and physics.
In total, Elon Musk's 14 children—with their diverse and often profound names—represent a family structure unlike any other in the public eye. From the traditional names of his eldest sons to the futuristic monikers of his youngest, the list is a testament to the billionaire's enduring quest for the extraordinary in both his professional and personal life.
