Who are the 14 children of Elon Musk?

Here is a complete, mother-by-mother breakdown using the best available records.

Children with Justine Wilson

• Nevada Alexander Musk (2002 – died at 10 weeks) – Musk’s first child, who died of SIDS (Wikipedia Musk family page).
• Griffin Musk and Vivian Jenna Wilson (twins, born 2004) – Vivian came out as transgender in 2022 and changed her name (Wikipedia Musk family page).
• Kai, Saxon, and Damian Musk (triplets, born 2006) (Wikipedia Musk family page).

Children with Grimes

• X Æ A-Xii (originally X Æ A-12, born May 2020) – the name sparked a media frenzy and reportedly conflicted with California naming rules (Wikipedia Musk family page).
• Exa Dark Sideræl Musk (born December 2021 via surrogate) (BabyNames.com celebrity name database).
• Techno Mechanicus Musk (born 2022, gender and exact date not publicly disclosed) (BabyNames.com celebrity name database).

Children with Shivon Zilis

• Strider Musk and Azure Musk (twins, born November 2022) – born via surrogate (BabyNames.com celebrity name database).
• Arcadia Musk (born February 28, 2024) (BabyNames.com celebrity name database).
• Seldon Lycurgus Musk (born reportedly in 2024 or 2025) – a fourth child with Zilis, reported in a 2025 overview (YouTube Musk family overview 2025).

Child with Ashley St. Clair

• Ashley St. Clair publicly claimed in 2025 that she gave birth to Musk’s child in September 2024. Some outlets reported the child’s name as Romulus (BabyNames.com celebrity name database). Paternity has not been legally confirmed.

Why did Musk use surrogates?

Musk has been open about using surrogates, particularly with Shivon Zilis. The twins Strider and Azure were born via surrogate in 2022, as was Exa Dark Sideræl with Grimes.

Reasons for surrogacy

• Musk has cited efficiency and family planning. In interviews, he framed surrogacy as a practical tool for expanding his family quickly (BabyNames.com celebrity name database).
• Grimes has spoken about medical logistics making surrogacy a preferred option for their second and third children.

Legal and personal aspects

Surrogacy arrangements are not publicly detailed, but there are no reported legal disputes involving the surrogates. Musk’s use of the method appears consistent: it allows him to have children with partners who are not romantically involved (Zilis was a top executive at Neuralink).

Do all of Elon Musk’s children live with him?

No. Most of Musk’s children live primarily with their mothers. The situation varies by child and agreement.

Custody arrangements

• Justine Wilson received primary custody of their six children after the divorce in 2008. Musk has visitation rights and shares custody in some form (Wikipedia Musk family page).
• Grimes’ children reportedly split time between her home and Musk’s properties, though neither has disclosed a formal arrangement.
• Shivon Zilis’ children live with her in Austin, Texas; Musk visits regularly.
• The child with Ashley St. Clair, if proven, would likely live with St. Clair.

Public statements

Musk has said in interviews that he is “very involved” in his children’s lives but acknowledges the logistical challenges of fathering children across multiple households.

Who named his son Xe a 12?

The unusual name X Æ A-12 was chosen jointly by Grimes and Elon Musk.

The meaning of X Æ A-12

• Grimes explained that “X” stands for “the unknown variable,” “Æ” is the Elvish spelling of “Ai” (love and/or artificial intelligence), and “A-12” refers to the Archangel 12 aircraft — Musk’s favorite plane (Wikipedia Musk family page).

Who chose the name

Both parents contributed. Musk later said the name was “primarily” Grimes’ creation, but he approved it.

Legal name change

California law requires a name to use only the 26 letters of the alphabet. The birth name was originally refused; they ultimately changed it to X Æ A-Xii (using Roman numeral “Xii” instead of “12”) to comply (Wikipedia Musk family page).
