The 14 Children of Elon Musk: A Definitive List of Their Unique Names

Elon Musk's children are often referred to as his "Musk-eteers," and their names are a fascinating mix of classical, technological, and deeply personal choices. Below is a chronological list of his known children, including the latest additions that made headlines in early 2025. The list includes 10 sons and 4 daughters, though one son, sadly, passed away in infancy.

Children with Justine Wilson (6 Children)

Musk's first wife, Canadian author Justine Wilson, is the mother of his first six children. Their first child tragically died, and the couple later conceived five more sons via IVF.

• Nevada Alexander Musk (Son): Born in 2002, Nevada tragically died of Sudden Infant Death Syndrome (SIDS) at just 10 weeks old.
• Griffin Musk (Son): Born in 2004 (twin). Griffin is one of the oldest living children in the Musk family.

• X Æ A-Xii (Son): Born in May 2020. Originally named X Æ A-12, the name was later changed due to California state law prohibiting numbers in a name. He is often nicknamed "X." The name is a nod to "the unknown variable" (X), the Elven spelling of AI/Love (Æ), and the A-12 Archangel aircraft.
• Exa Dark Sideræl Musk (Daughter): Born via surrogate in December 2021. She is nicknamed "Y." The name is a reference to the supercomputing term exaFLOPS, the unknown (Dark), and "the true time of the universe" (Sideræl).
• Techno Mechanicus (Son): Born sometime in 2023. Known as "Tau," this name was revealed in September 2023. It is perhaps the most direct reference to technology and engineering among his children.

Children with Shivon Zilis (4 Children)

Shivon Zilis, an executive at Musk's Neuralink company, has four children with the billionaire. Their relationship and the births of their children have been a major focus of media attention in recent years, particularly with the latest announcements.

• Strider (Son): Born in November 2021 (twin). Strider and his twin, Azure, were born just weeks before Exa Dark Sideræl, a fact that surprised the public when it was revealed.
• Azure (Daughter): Born in November 2021 (twin).
• Arcadia (Daughter): Born prior to the 2025 announcement. Her name was quietly revealed in a recent update about the family.
• Seldon Lycurgus (Son): Announced in February 2025. This latest addition to the Zilis-Musk family has a unique, classically-inspired name. It was also revealed that one of their sons has the middle name Sekhar, a tribute to the Indian Nobel laureate C.V. Raman, reflecting Zilis's half-Indian heritage.

Child with Ashley St. Clair (1 Child)

In a surprising development announced in February 2025, conservative author and journalist Ashley St. Clair revealed she had a child with Elon Musk.

• Romulus (Son): Born in September 2024. The name Romulus, shared with one of the legendary founders of Rome, continues the theme of powerful, historical names in the Musk family.

The Philosophy Behind the Names: Tech, History, and Science

The choice of names for Elon Musk's children is far from random; it is a clear reflection of his core interests and worldview. The names serve as a fascinating insight into the mind of one of the world's most influential figures, blending high-tech concepts with deep historical and mythological references. The naming convention, especially for the sons, often leans into themes of future technology and classical power.

The Techno-Futuristic Naming Trend

The most famous example, X Æ A-Xii, is a pure expression of this trend. The 'X' is a nod to his company X.com and the unknown variable in mathematics. The 'Æ' (Ash) is a linguistic bridge to 'AI' (Artificial Intelligence), while 'A-Xii' references the Lockheed A-12 reconnaissance aircraft, a precursor to the SR-71 Blackbird. Similarly, Techno Mechanicus (Tau) is a direct, bold statement about the future being driven by engineering and mechanics.

The name Exa Dark Sideræl for his daughter with Grimes also follows this pattern, referencing exaFLOPS, a measure of supercomputer performance. These names are not just unique; they are a form of conceptual art, embedding complex ideas about science and the future into a child's identity.

Classical and Historical Entities

In contrast to the futuristic monikers are the names that draw on classical history and literature, demonstrating a different facet of Musk's interests. The recent addition of Seldon Lycurgus and Romulus are prime examples. Seldon is likely a nod to Hari Seldon, the fictional founder of Psychohistory in Isaac Asimov's Foundation series, one of Musk's favorite works of science fiction. Lycurgus was the legendary lawgiver of Sparta, suggesting a reverence for order and powerful governance. Romulus, as mentioned, is a direct link to the founding of Rome, embodying a sense of beginning and empire-building.

Even the names of his older children—Griffin, Kai, Saxon, and Damian—while more conventional, carry a sense of strength and classical or mythological weight. The name Strider, one of the twins with Shivon Zilis, is also a nod to fantasy literature, being the original name of Aragorn in J.R.R. Tolkien's The Lord of the Rings.

The revelation of the middle name Sekhar, a tribute to Nobel laureate C.V. Raman, is a significant entity, grounding one of the children in a real-world scientific legacy and honoring the family's Indian heritage through Shivon Zilis.

The Growing Musk Dynasty and Future Speculations

With 14 known children, Elon Musk is actively living out his stated belief that people with high IQs should reproduce more to combat falling birth rates and ensure the survival of civilization. This personal mission has turned his family into a subject of global fascination and debate. The constant addition of new children and the revelation of their distinct names—each a unique entity—ensures that the topic of the "Musk-eteers" remains current and highly searched.

The latest updates regarding Seldon Lycurgus and Romulus confirm that the trend of highly conceptual and meaningful names is continuing. As the children grow up, the world will be watching to see how the unique identities bestowed upon them—from X Æ A-Xii to Techno Mechanicus and Vivian Jenna Wilson—will shape their own paths. The Musk family, with its complex structure and extraordinary names, is a living experiment in futurism, history, and the power of personal conviction.
