 It is also one of the youngest counties in the state having been created in 1906 after it was separated from Itasca County.The name "Koochiching" comes from either the Ojibwe word "Gojijiing" or Cree "Kocicīhk" (recorded in some documents as "Ouchichiq"), both meaning "at the place of inlets," referring to the neighboring Rainy Lake and River.Reverend J.A.
