Ozhaguscodaywayquay (Ozhaawashkodewekwe: Woman of the Green Glade), also called Neengay (Ninge: "My mother") or Susan Johnston (c. 1775 – c. 1840), was an important figure in the Great Lakes fur trade before the War of 1812. She married the British fur trader John Johnston, a "wintering partner" of the North West Company. They had prominent roles in the crossroads society of Sault Ste. Marie, Michigan and the territory before 1830, and entertained notable visitors from a variety of disciplines. Their daughter Jane Johnston Schoolcraft has become recognized as the first Native American literary writer in the United States.
She was born as Ozhaguscodaywayquay (Green Prairie Woman) into an Ojibwe (also known as Ojibwa) family in Chequameqon, near present-day La Pointe, Wisconsin and Chequamegon Bay; her father was the famous war chief Waubojeeg (The White Fisher). Waubojeeg had been a war leader when younger, and he became civil chief as an elder in his community at Chequamegon.
In 1790, Scots-Irish fur trader John Johnston traveled to Mackinac Island and then to Chequamegon by canoe, where he asked Waubjoeeg for permission to marry his youngest daughter, Ozhaguscodaywayquay. Waubojeeg was cautious, as he had seen other white traders later abandon their native wives, and told Johnston to return to Montreal, and if he returned to Chequamegon in the spring, Waubojeeg would consider his proposal. Johnston returned and Waubojeeg agreed to the marriage. Ozhaguscodaywayquay married John Johnston in 1793. However, it appears she was not consulted, as after the marriage she ran off to her grandfather, however her father found her, beat her with a stick, threatened to cut off her ear, and returned her to Johnston. Waubojeeg's motives for his actions are unclear, however neither the compelled marriage nor violence enforcing it appear typical of Ojibwe marriages or Ojibwe fur-trade marriages.
