Vivian Jenna Wilson’s Siblings: Meet The Large Family of Elon Musk’s Daughter

Vivian Jenna Wilson, formerly known as Xavier Alexander Musk, is the transgender daughter of billionaire entrepreneur Elon Musk and his first wife, Justine Wilson (Justine Musk).

Born in 2004, Vivian has garnered public attention for her gender transition and her decision to legally change her name in 2022 to reflect her identity and her mother’s maiden name.

Vivian Jenna Wilson was born in California, United States, on April 15, 2004. She was one of twins conceived via in vitro fertilization (IVF) alongside her twin brother, Griffin Musk. Their birth followed the tragic loss of their older brother, Nevada Alexander Musk, who passed away at 10 weeks old due to sudden infant death syndrome (SIDS) in 2002.

This tragedy influenced the decision to pursue IVF, as Elon Musk and Justine Wilson sought to expand their family after Nevada‘s death.

Vivian Jenna Wilson is of mixed ethnicity, reflecting her parents’ diverse backgrounds. Elon Musk, her father, was born in Pretoria, South Africa, to a Canadian mother, Maye Musk, and a South African father, Errol Musk.

Maye Musk‘s ancestry includes English, Scottish, and Dutch roots, while Errol Musk has Afrikaner (Dutch, French, and German) heritage. Justine Wilson, Vivian‘s mother, is Canadian, with English and French-Canadian ancestry. As a result, Vivian‘s ethnicity is a blend of European (English, Scottish, Dutch, French, and German) and Afrikaner heritage.

Regarding religion, Elon Musk has publicly identified as an atheist or agnostic, expressing skepticism about organized religion in various interviews. Justine Wilson has not publicly discussed her religious beliefs in detail, but there is no indication that religion played a significant role in Vivian‘s upbringing. Vivian‘s religious beliefs remain private, and there is no public information suggesting adherence to a specific faith.

Vivian Jenna Wilson is the daughter of Elon Musk and Justine Wilson, who were married from 2000 to 2008. Elon Musk, born on June 28, 1971, in Pretoria, South Africa, is a billionaire entrepreneur, inventor, and business magnate. He is the founder and CEO of Tesla (electric vehicles), SpaceX (aerospace and space exploration), Neuralink (neurotechnology), and The Boring Company (infrastructure).

Musk‘s ambitious ventures and controversial public persona have made him one of the world’s most recognized figures. His relationship with his children, including Vivian, has been scrutinized, particularly following Vivian’s decision to distance herself from him.

Justine Wilson, born on September 2, 1972, in Peterborough, Ontario, Canada, is a Canadian author known for her fantasy and science fiction novels, including BloodAngel (2005) and Uninvited (2007). She met Elon Musk while both were students at Queen’s University in Kingston, Ontario.

Justine has been open about the challenges of their marriage, including the grief following Nevada‘s death and the dynamics of raising their children. After their divorce in 2008, Justine retained custody of their five living children, including Vivian.

Vivian‘s decision to change her name to Vivian Jenna Wilson in 2022, adopting her mother’s maiden name, was seen as a symbolic step to distance herself from her father. In court documents, Vivian stated, “I no longer live with or wish to be related to my biological father in any way, shape, or form,” citing gender identity and family dynamics as reasons for the change.

Vivian Jenna Wilson has five siblings from her parents’ marriage, all conceived via IVF. Additionally, she has half-siblings from Elon Musk‘s relationships with singer Grimes (Claire Boucher) and Neuralink executive Shivon Zilis.

Nevada Alexander Musk (2002–2002), Vivian‘s older brother, who passed away at 10 weeks old due to SIDS. His death profoundly impacted the family, leading to the use of IVF for subsequent children.

Griffin Musk (born April 15, 2004), Vivian‘s twin brother, who has largely remained out of the public eye. Griffin has been spotted accompanying Elon Musk on various occasions, including international meetings.

Kai Musk (born January 1, 2006), one of the triplets, alongside Damian Musk and Saxon Musk. Kai, like his brothers, has maintained a low profile.

Saxon Musk (born January 1, 2006), another of the triplets, Saxon has been referenced in Elon Musk‘s social media posts, including a 2021 post expressing optimism about the year ahead.

Damian Musk (born January 1, 2006) is the third triplet. Biographer Walter Isaacson has described him as a prodigy in classical music, physics, and mathematics. He has been a vegetarian since age 8.

Vivian‘s half-siblings from Elon Musk‘s other relationships include X Æ A-Xii Musk (born May 2020) and Exa Dark Sideræl Musk (born December 2021), with Grimes. Tau Techno Mechanicus Musk (born June 2022), also with Grimes.

Strider Musk (born 2021), Azure Musk (born 2021), and an unnamed child (born June 2024) with Shivon Zilis. Elon Musk‘s multiple relationships and publicized views on population growth have shaped the Musk family’s complex dynamics, including Vivian’s estrangement from her father.

Vivian Jenna Wilson‘s education has been unconventional, reflecting Elon Musk’s approach to schooling for his children. During her early years, Vivian and her siblings were educated at a unique school founded by Elon Musk at SpaceX headquarters in Hawthorne, California. This school, known as Ad Astra (Latin for “to the stars”), was designed to provide innovative, hands-on learning experiences tailored to the needs of Musk‘s children and select SpaceX employees’ children.

Ad Astra employed unconventional teaching methods, focusing on problem-solving, critical thinking, and interdisciplinary learning rather than traditional curricula. Elon Musk has described the school as an educational experiment, though specific details about its operations remain limited.

The school reportedly closed or transitioned to other forms, with some reports suggesting it evolved into an online program called Astra Nova. Vivian‘s education beyond Ad Astra is not publicly documented, and whether she attended traditional schools or pursued alternative educational paths is unclear.
