John Johnston (1762–1828) was a wealthy and successful British fur trader for the North West Company at Sault Ste. Marie when it was still Canadian territory before the War of 1812. He was a prominent citizen and leader in the Michigan Territory of the United States, although he never became a US citizen. He married Ozhaguscodaywayquay (Woman of the Green Glade), daughter of Waubojeeg (White Fisher), a prominent Ojibwe war chief and civil leader from what is now northern Wisconsin.

Johnston went to Sault Ste. Marie, a journey which then took several weeks, where he settled on the south side of the river. There Johnston met Ozhaguscodaywayquay (Woman of the Green Glade), daughter of Waubojeeg (White Fisher), a prominent Ojibwe war chief and civil leader from what is now northern Wisconsin. Johnston fell in love with the Chief Waubojeeg's daughter, but the Chief was skeptical of white men. He initially refused when Johnston asked for his daughter in marriage, saying:
