The Four Mothers: Diverse Partnerships in the Musk Family
The complex family structure is defined by four distinct relationships, each bringing a unique dynamic to the world of the tech billionaire. The common thread is the use of cutting-edge technology like IVF and surrogacy, alongside a shared philosophical belief in the importance of procreation.
Justine Wilson: The First Wife and Mother of Six
Justine Wilson, a Canadian author, was Musk’s first wife. The pair were married from 2000 to 2008. Their journey into parenthood was marked by tragedy and technology. After losing their first son, Nevada Alexander, to SIDS, they turned to IVF to have their subsequent children. Justine Wilson is the mother of the eldest living children: the twins, Griffin and Vivian, and the triplets, Kai, Saxon, and Damian. Their co-parenting relationship has been publicly discussed, with Wilson often providing insights into the challenges of raising children with a world-famous father.
Grimes: The Artistic Naming Conventions
Claire Boucher, known professionally as Grimes, an experimental musician, shares three children with Musk: X Æ A-Xii (X), Exa Dark Sideræl (Y), and Techno Mechanicus (Tau). Their relationship became a cultural phenomenon, largely due to the highly unusual, science- and mythology-inspired names they chose for their children. The names themselves are a reflection of Musk’s obsession with space, technology, and futuristic concepts, providing a clear link between his business interests (SpaceX, X Corp) and his personal life. Grimes has often provided the public with the meaning of the names, confirming the deep, technical layers behind them.
The Newest Chapters: Neuralink, Procreation, and Public Controversy
The most recent additions to the Musk family have brought the total count to 14 and involved two new mothers, highlighting the billionaire’s commitment to his "underpopulation" concerns. These births have drawn immense public attention, not only because of the sheer number of children but also due to the circumstances surrounding their arrival.
Shivon Zilis: The Neuralink Connection
Shivon Zilis, an executive at Musk's brain-chip company, Neuralink, and a director at X Corp, has four children with Musk: twins Strider and Azure, and the two youngest, Arcadia and Seldon Lycurgus Musk. The fact that Musk is having children with an executive from his own company, a woman deeply involved in his futuristic technological vision, underscores his belief that highly intelligent individuals should procreate. The twins were born via IVF in 2021, and the two subsequent children, Arcadia and Seldon Lycurgus, arrived in 2024 and 2025, respectively, solidifying Zilis as the mother of the second-largest number of his children.
Ashley St. Clair: The Romulus Revelation
The most recent public controversy centers on the birth of Romulus St. Clair, the son of conservative influencer Ashley St. Clair. While the birth occurred in late 2024, the public announcement and the revelation of the child's name, Romulus, were a major news event in early 2025. St. Clair publicly claimed the paternity and detailed a dramatic dispute with Musk, adding a layer of media drama to the billionaire's already complex family life. The name Romulus, shared with the mythical founder of Rome, continues the theme of grand, historical, or technological naming conventions.
The Future of the Musk Dynasty: Name Changes and Legacy
The sheer size and complexity of Elon Musk's family have created a unique modern dynasty, one that is often at the intersection of technology, philosophy, and celebrity. The most poignant detail remains the legal name change of Vivian Jenna Wilson, who not only transitioned but explicitly requested to drop the Musk surname. Her petition, filed in 2022, stated she wished to be recognized with her mother's maiden name, citing her desire to no longer be associated with her biological father. This public separation by his adult child stands in stark contrast to Musk’s public advocacy for large families and his own legacy.
As the family continues to grow, with a total of 14 children confirmed as of late 2025, the "Musk-eteers" represent a fascinating case study in modern parenthood, blending traditional family values with futuristic technology and unprecedented public scrutiny. Whether the next child will arrive in 2026, or if the current count will hold, the world remains keenly interested in the ever-expanding lineage of the world's most famous tech visionary. The names—from Kai and Saxon to X Æ A-Xii and Seldon Lycurgus—will undoubtedly continue to spark conversation about the intersection of personal life and global influence.
