I don't know if I'm stating the obvious, but you only need to bootstrap if you're writing a compiler in the language it's compiling. So any language compiler written in a different language isn't bootstrapped. Even if you're using a loose definition of "root" as in a parent language is any language involved in writing another language, I doubt there is one root. There are certainly have been languages and computer architectures (with assembly languages) that are independent islands.
