Ma'chello's homeworld
From The Stargate Omnipedia
World once populated by billions of humans. Knowing he was key to their fight with the Goa'uld, two billion of Ma'chello's people died when they refused to hand him over. Their world was destroyed in the process.
Ma'chello was found by SG-1 on planet P3C-599, though it is not certain that this was his original homeworld. If that world was left decimated by the Goa'uld, it seems likely that he went elsewhere.
