From X ? A-Xii Musk to Tau Techno Mechanicus Musk: Elon Musk's 13 kids have unique names, but what do they really mean?

Elon Musk, the tech billionaire, is now the father of fourteen children after Shivon Zilis broke the news on February 28, 2025, that the couple is expecting a new baby.

The 39-year-old Neuralink director announced on the social media platform X (formerly called Twitter) that she and Musk had a second son, Seldon Lycurgus. The announcement came after a Make America Great Again (MAGA) influencer claimed in February that she recently gave birth to Elon Musk's 13th child five months earlier.

Sharing a post on X about the same, she wrote, "Discussed with Elon and, in light of beautiful Arcadia＊s birthday, we felt it was better to also just share directly about our incredible son Seldon Lycurgus. Built like a juggernaut, with a solid heart of gold. Love him so much."

Elon Musk's 13 kids have unique names

Elon Musk is famous for many things, including X, Tesla, SpaceX, and more. However, he is also known for being a father of 13 children, each with distinctive and unconventional names. From gaming and tech-inspired choices to mythological influences, Musk and his partners have given their kids that are sure to intrigue and raise questions.

Nevada Alexander Musk (2002): Nevada was Musk's first child, with his first wife, Justine Wilson. Unfortunately, he passed away at just 10 weeks old due to sudden infant death syndrome (SIDS).

The name 'Nevada' is mostly inspired by the U.S. state, symbolising vast landscapes and frontier spirit. While 'Alexander' is of Greek origin, which means ※defender of the people."

Griffin Musk (2004): Next comes the one with Musk and Justine Wilson's twins, and the Griffin's name comes from the mythological background, which means a creature with the body of a lion and the head of an eagle. It is also a symbol of strength and guardianship.

Vivian Jenna Wilson (2004): Griffin's twin was originally named Xavier but changed her name to Vivian Jeanna Wilson in 2022.

Kai Musk (2006): Born as part of Musk and Justine＊s triplets, Kai is a commonly used name across various cultures, meaning 'sea' in Hawaiian and 'forgiveness' in Japanese.

Saxon Musk (2006): Another triplet, Saxon's name is taken from the Germanic tribe that inhabited parts of central and northern Germany from Roman times.

Damian Musk (2006): The last of the triplets, Damian's name is of Greek origin, 'to tame' or 'subdue.'.

X ? A-Xii Musk (2020): Born to Musk and Canadian musicians Grimes, 'X' represents 'the unknown variable,' and ＆?＊ is an elven spelling of 'AI' (which means love/artificial intelligence).
