Decoding the Cryptic: The Meanings Behind the Most Unique Names

The children Musk shares with Grimes and Shivon Zilis possess names that are less traditional and more reflective of the couple's shared interests in futurism, science fiction, and technology. These names are a goldmine for understanding the family’s unique worldview, blending classical references with cutting-edge concepts.

The Grimes Trilogy: X, Y, and Tau

The three children Musk shares with Canadian musician Grimes (Claire Boucher) have names that sound like complex equations or ancient code. Grimes herself has often taken to social media to explain the complex etymology of each name, adding layers of topical authority to the choices.

• X Æ A-Xii (X)
  • X: Represents the "unknowable variable" in mathematics.
  • Æ: The Elven spelling of AI, which stands for Artificial Intelligence and/or "love" in some languages.
  • A-Xii: A reference to the SR-71 Blackbird—the couple's favorite aircraft—which is often called the "Archangel-12" or "A-12." The "Xii" is the Roman numeral equivalent.
• Exa Dark Sideræl (Y)
  • Exa: A reference to exaFLOPS, a term in supercomputing that measures the ability to perform one quintillion floating-point operations per second.
  • Dark: Represents the "unknown," specifically dark matter and the "great unknown" of the universe.
  • Sideræl: An Elven spelling of "sidereal," which refers to the true time of the universe and "star time," a concept Grimes finds more accurate than Earth-based time.
• Techno Mechanicus (Tau)
  • Techno Mechanicus: Directly translates to a master of technology or mechanics, a clear nod to Musk's engineering and tech empire.
  • Tau: The nickname is a reference to the Greek letter, often used in physics and mathematics, symbolizing the ratio of a circle's circumference to its radius (2π) or a specific type of lepton particle.

The Zilis Quartet: Strider, Azure, Arcadia, and Seldon Lycurgus

The four children Musk shares with Shivon Zilis, a top executive at his brain-chip company Neuralink, also carry names with profound, often literary and historical, references. Their births highlight Musk's belief in combating declining birth rates among highly educated populations.

The twins, Strider Sekhar Sirius and Azure Astra Alice, were born via IVF just weeks before Exa Dark Sideræl, creating a unique timeline for the Musk family. The names themselves are a blend of mythological, astronomical, and literary entities.

• Strider Sekhar Sirius and Azure Astra Alice
  • Strider: A likely nod to Aragorn's alias in J.R.R. Tolkien's *The Lord of the Rings*.
  • Sirius: The brightest star in the night sky, also known as the "Dog Star."
  • Azure Astra Alice: Azure and Astra are celestial-themed, meaning "sky-blue" and "star," respectively, continuing the family's cosmic naming convention.
• Arcadia Musk
  • Arcadia: A region in Greece idealized in classical literature as a pastoral paradise, representing a simple, idyllic existence. It is a name rooted in classical antiquity.
• Seldon Lycurgus Musk
  • Seldon: This name is a clear and powerful reference to Hari Seldon, the fictional mathematician in Isaac Asimov's seminal Foundation science fiction series. Hari Seldon is the creator of psychohistory, a field of mathematics that can predict the future of large populations.
  • Lycurgus: A nod to the legendary, and possibly mythical, Spartan lawgiver from the 9th century BC. Lycurgus is credited with shaping the militaristic and disciplined society of ancient Sparta, known for its focus on strength and civic duty.

The Wilson Sextuplets: The Foundation of the Family

Musk's first six children were with his first wife, Canadian author Justine Wilson. These names are markedly more traditional, showing a clear shift in naming philosophy over the years. The birth of the triplets, Kai, Saxon, and Damian, followed a tragic loss that profoundly affected the couple.

The tragic passing of his firstborn, Nevada Alexander Musk, from SIDS in 2002, was a foundational event in the family's history. The subsequent births of the twins and then the triplets via IVF demonstrated a strong desire to build a large family. The decision by one of the twins to legally change her name to Vivian Jenna Wilson (adopting her mother's surname) in 2022 was a highly publicized personal choice.

The sheer number and diversity of the names—from the classic Griffin and Damian to the futuristic Techno Mechanicus and the literary Seldon Lycurgus—underscore a fascinating intersection of science, fiction, history, and personal ambition. As of 2025, Elon Musk’s 14 children represent one of the most unique and closely watched families in the world, with each name serving as a tiny window into the mind of the world’s most famous futurist.
