The name of the son of Elon Musk and his partner Grimes was originally given to the X Æ A-12, a name that California law did not prohibit, but simply did not recognize, which is practically the same thing. In California, only 26 letters of the English alphabet can be used, no numbers or other symbols are allowed, except for the apostrophe as in the names O'Connor. Elon and Grimes found the solution stylish and changed the name, as the law does not allow numbers.
In an Instagram post , someone asked Grimes if they changed the boy's name and she responded by revealing her new name: X Æ A-Xii. The name is the same simply Xii is the substitute for the number 12, brought in the form of a Roman number (XII).
