Ancient and Modern Michilimackinac, by J. J. Strange, the Mormon King with Supplement by Judge Charles R. Brown

"The name of the Island of Michilimackinac and the Promontory of the Old Michilimackinac is derived from the Indian words Michi Maikinac - Great Turtle; both places, as seen from a distance on the water, resembling the turtle. The Ojibewas, (Chippewas,) Ottowas and Pottawatomies, who settled the country after the name was in use, hold it synonymous with Michimauhinonk, the place of mighty spirits. The Island, according to Indian tradition, is the birth place of Michabow, the Indian God of Waters.
