Pronunciation Guide & Meanings

- Pronounced: “X Ash A Twelve.”
- Meaning:
- “X” represents the unknown variable.
- “Æ” is a character from some languages and used by Musk and Grimes to symbolize “AI” (artificial intelligence).
- “A-12” referred to the Archangel 12 aircraft — the precursor to the SR-71 Blackbird, Musk’s favorite plane.
- Later changed to “A-Xii” (Roman numerals) to comply with name regulations.
Exa Dark Sideræl
- Pronounced: “Ex-uh Dark Sigh-deer-eel.”
- Meaning:
- “Exa” comes from “exa-flops,” a supercomputing term.

- “Sideræl” (variant of sidereal) means “star time” — relating to deep space.
Techno Mechanicus
- Nickname: “Tau.”
- Meaning: Combines “Techno” (technology, innovation) and “Mechanicus” (mechanical or engineer). “Tau” (τ) represents 2π — a mathematical constant Musk often references.
Traditional Names

- The later names — Arcadia, Azure, Strider, Seldon, and Romulus — reflect Musk’s interest in science fiction, mythology, and classical history.
Timeline of Births & Key Family Moments
Early 2000s: Beginning with Justine Wilson
Elon Musk’s first marriage was to Canadian author Justine Wilson. The couple had six children together through natural and IVF births. Tragically, their first child, Nevada Alexander, died of SIDS at just 10 weeks old.
In 2004, twins Griffin and Vivian were born, followed by triplets Kai, Saxon, and Damian in 2006. After their divorce in 2008, the couple shared custody of their five surviving children.
2020–2022: The Grimes Era
In 2020, Musk and musician Grimes announced the birth of their son X Æ A-12 (later X Æ A-Xii). The unusual name made headlines worldwide. In 2021, the couple welcomed a daughter, Exa Dark Sideræl, via surrogate. In 2022, they quietly revealed a third child named Techno Mechanicus (nicknamed Tau).
Despite their on-and-off relationship, both Musk and Grimes describe their parenting style as cooperative, even if they don’t live together full-time.
2021 Onward: Shivon Zilis & Neuralink Connection
In late 2021, Musk fathered twins — Strider and Azure — with Shivon Zilis, a Neuralink executive. Their birth became public through court documents that listed Musk as the father.
In 2024, Zilis gave birth to another child named Arcadia, followed by Seldon Lycurgus in 2025. These children make up Musk’s youngest confirmed offspring.
2024–2025: Additional Claims
Rumors surfaced that Elon Musk also fathered a child named Romulus with influencer Ashley St. Clair. While widely reported, this claim hasn’t been officially confirmed by Musk or his representatives.
Confirmed vs Rumored Children
| Category | Names |
|---|---|
| Confirmed | Nevada Alexander, Griffin, Vivian, Kai, Saxon, Damian, X Æ A-Xii, Exa Dark Sideræl, Techno Mechanicus, Strider, Azure, Arcadia, Seldon Lycurgus |
| Reported / Unconfirmed | Romulus Musk |
This clear distinction helps readers understand which births are publicly verified and which remain speculative — a detail most articles overlook.
Profiles of the Mothers
Justine Wilson
Elon Musk first wife and mother to his six oldest children. She met Musk at university, and together they built their family before parting ways in 2008. Justine has written extensively about her experience and continues to co-parent amicably.
Grimes (Claire Boucher)
A Canadian musician, artist, and producer known for her avant-garde style. She shares three children with Musk — X Æ A-Xii, Exa Dark Sideræl, and Techno Mechanicus. Their relationship has been described as fluid but friendly, with both remaining involved in their children’s lives.
Shivon Zilis

The Meaning Behind Elon Musk’s Parenting Philosophy
Elon Musk often talks about population decline as one of humanity’s biggest risks. He believes having children is not only a personal choice but a societal duty. He’s repeatedly stated that the world needs more people — especially intelligent and motivated ones — to sustain civilization.
For Musk, having a large family is consistent with his futuristic outlook: building a future where humans expand beyond Earth. He once mentioned he wants to “populate Mars,” and in a way, his growing family represents that mindset on a smaller scale.

This balance of fame and privacy has made Musk’s family one of the most discussed yet least personally exposed celebrity families.
