 The spelling Saghalien may be found in historical texts.Choka (or Tchoka) is another name found in the early literature and seems to have been the name used by the islanders themselves, but it is not clear whether these were the Gilyak or the Ainu.The European names derive from misinterpretation of a Manchu name "sahaliyan ula angga hada" ("peak/craggy rock at the mouth of the Amur River").
