Elon Musk is publicly known to have 14 children with four women. They include six children with Justine Wilson, three with musician Grimes, four with Shivon Zilis and one with Ashley St. Clair. One of the 14, Nevada Alexander Musk, died in infancy. The remaining publicly identified children are living.
Elon Musk’s family has expanded over more than two decades, and the public record has changed as previously private births became known. His children range from adult twins and triplets to much younger children born in the 2020s. This guide explains who they are, who their mothers are and what is reliably known about each family group.

Elon Musk Children With Justine Wilson
Elon Musk’s first six children were with Canadian author Justine Wilson. Their first child, Nevada Alexander Musk, was born in 2002 and died from sudden infant death syndrome at about 10 weeks old. The couple subsequently had twins Griffin and Vivian in 2004, followed by triplets Kai, Saxon and Damian in 2006.
The family story changed significantly after Nevada’s death. Wilson and Musk went on to have their later children through IVF, according to published accounts. Musk and Wilson married in 2000 and divorced in 2008. Their children from this relationship are:
- Nevada Alexander Musk, born in 2002, died in infancy.
- Griffin Musk, born in 2004.
- Vivian Jenna Wilson, born in 2004.
- Kai Musk, born in 2006.
- Saxon Musk, born in 2006.
- Damian Musk, born in 2006.
Vivian Jenna Wilson legally changed her name and gender designation in 2022 after turning 18. The court filing cited both her gender identity and her wish not to be associated with her biological father. She uses her mother’s surname.
Elon Musk Children With Grimes
Elon Musk and musician Grimes have three children together: X Æ A-Xii, Exa Dark Sideræl and Techno Mechanicus. Their relationship began publicly in 2018, and although they later separated, they have remained connected through their children.
Their first child, X Æ A-Xii, was born in May 2020 and is widely known simply as X. Their daughter Exa Dark Sideræl was born in December 2021 via surrogate and is often referred to as Y. Their third child, Techno Mechanicus, was born in June 2022 and is commonly nicknamed Tau.
Grimes has generally sought greater privacy for the younger children. That means detailed information about their everyday lives, education and development should not be assumed simply because their father is one of the world’s most recognisable technology entrepreneurs.
Elon Musk Children With Shivon Zilis
Shivon Zilis is the mother of four of Musk’s publicly identified children: Strider, Azure, Arcadia and Seldon Lycurgus. Zilis is an executive at Neuralink, one of Musk’s companies.
The twins Strider and Azure were born in November 2021. Their existence became public after court documents concerning their surnames were reported in 2022. Musk and Zilis later welcomed daughter Arcadia, whose birth in 2024 became public later than the birth itself.
In February 2025, Zilis announced the birth of Seldon Lycurgus, another son with Musk. Reuters reported that Zilis described Seldon as their fourth child together. The announcement followed the public disclosure by Ashley St. Clair that she had also had a child with Musk.
This makes Zilis the mother of the largest group of Musk’s living children from a single relationship, with four publicly identified children.
Elon Musk’s Child With Ashley St. Clair
Ashley St. Clair is the mother of Romulus, a son born in 2024. St. Clair publicly announced in February 2025 that Musk was the child’s father. The child’s name, Romulus, was subsequently reported publicly.
The paternity became part of a public legal dispute. Reporting in April 2025 said a paternity test gave a 99.9999% probability that Musk was the father, although coverage also noted that Musk had not publicly identified the child as his in the same way that the mothers had.
For that reason, the most precise wording for an SEO article is that Romulus is a publicly identified child attributed to Musk, rather than speculating about private family arrangements or making claims beyond the documented reporting.
Elon Musk Children: Names and Birth Years
The family can be easier to understand when arranged chronologically. The following list focuses on publicly reported information rather than private details that have not been reliably established.
- Nevada Alexander Musk, 2002, with Justine Wilson, died in infancy.
- Griffin Musk, 2004, with Justine Wilson.
- Vivian Jenna Wilson, 2004, with Justine Wilson.
- Kai Musk, 2006, with Justine Wilson.
- Saxon Musk, 2006, with Justine Wilson.
- Damian Musk, 2006, with Justine Wilson.
- X Æ A-Xii, 2020, with Grimes.
- Strider, 2021, with Shivon Zilis.
- Azure, 2021, with Shivon Zilis.
- Exa Dark Sideræl, 2021, with Grimes.
- Techno Mechanicus, 2022, with Grimes.
- Arcadia, 2024, with Shivon Zilis.
- Romulus, 2024, with Ashley St. Clair.
- Seldon Lycurgus, announced in 2025, with Shivon Zilis.
People’s detailed family guide and Reuters’ reporting on Seldon support the overall list, while individual birth details are not equally public for every child.
Why Do Some Websites Give Different Numbers?
Different figures appear because Musk’s family has grown partly outside the public spotlight. Some births were disclosed months or years after they occurred, while other reports have used different definitions of what counts as publicly confirmed.
For example, Seldon Lycurgus was announced in February 2025, while Arcadia’s existence had become public before her name was disclosed. Romulus was also initially reported as a claimed child before later paternity-test reporting. Consequently, older articles can show 12 or 13 children even though newer reporting lists 14.
It is therefore more accurate in 2026 to describe the figure as 14 publicly identified children, rather than claiming that every aspect of Musk’s private family life is known. Some reporting has suggested that the total number could be higher, but such claims are not sufficiently established to add further names to a factual list.
Elon Musk Children and Family Privacy
Many details about Musk’s younger children remain private, and that distinction matters when discussing a celebrity family. Publicly available information can establish names, mothers and approximate birth years, but it does not provide a complete picture of where every child lives, attends school or spends private family time.
The same principle applies to claims circulating on social media. A viral post or unsourced celebrity website should not automatically be treated as evidence of another child, a private relationship or a family arrangement. The publicly documented list currently provides a much firmer basis for understanding Musk’s family.
Conclusion
Elon Musk children currently refers to 14 publicly identified children with four mothers: Justine Wilson, Grimes, Shivon Zilis and Ashley St. Clair. The family includes adult children from Musk’s first marriage, three children with Grimes, four with Zilis and Romulus with St. Clair. Nevada Alexander Musk, Musk’s first child, died in infancy.
Because several births were revealed gradually, the number reported online has changed over time. For a current 2026 article, 14 publicly identified children is the clearest figure supported by the available reporting, while private or unverified claims should be kept separate from the documented family record.
