The Big Picture: How Many Children Does Elon Musk Have?

As of 2025, Elon Musk has 14 known children.
One of his children died in infancy, so he is the father of 13 living children.
These children come from four different women: Justine Wilson, Grimes, Shivon Zilis, and Ashley St. Clair.
The variety in his children’s names is extraordinary—from classic names like Griffin and Kai, to very futuristic ones like X Æ A-Xii or Seldon Lycurgus.

Musk’s family is large and diverse, reflecting both his personal beliefs and his unique lifestyle.

The First Family: Children with Justine Wilson

Elon Musk’s first marriage was with Canadian author Justine Wilson. During their time together, they had six children (though not all survived). Here are their stories:

Child	Year of Birth	Notes
Nevada Alexander	2002	Their first child, who tragically died at 10 weeks old from sudden infant death syndrome (SIDS).
Vivian Jenna Wilson (formerly Xavier)	2004	One of their twins. Vivian later changed her name and legally adopted her mother’s surname.

Kai	2006	One of their triplets, conceived via IVF.
Saxon	2006	Another of the triplets.

The triplets (Kai, Saxon, and Damian) were all born in January 2006 using in vitro fertilization (IVF).

Elon Musk later began a relationship with musician Grimes (real name Claire Boucher). Together, they had three children, each with a very unique name and story.

Another mother of Elon Musk children is Shivon Zilis, a Neuralink executive. With her, Musk has had several children: twins and more.

Strider Sekhar Sirius and Azure Astra Alice
- Born: November 2021.
- “Strider” might be a reference to a character in The Lord of the Rings.
- “Azure” suggests the sky or stars (azure = blue sky), and “Astra” means “of the stars.”

- Her name has a poetic ring: “Arcadia” is often used to refer to an idyllic or peaceful place.
