I really must apologise for the "9". I didn't know Greece had the 9 at the beginning. I thought, the 9 was left for countries like Tobago or Samoa. Sorry about that!
I am always open to new theories, and the evidence you list is impressive indeed. I've seen it before that scholars keep copying information from one book to another without rechecking it. So what you say about Greek etymology may be the case. Unfortunately I don't have one book on this, and although I can read and understand ancient Greek, I would probably lost in a Greek-Greek dictionary of the kind.
So I'd be glad to be the "winner" in Socrates
