Hamlet53 has it.
The Ojibwe (Chippewa) call Lake Superior Gichigami which means "big water" (from wikipedia). Longfellow wrote Hiawatha, an epic poem sort of based on the legends of Hiawatha. There's a lot of names involved along the way because Hiawatha was the great bringer of peace who brought together five at first and later six tribes together the Iroquois Confederacy.
Longfellow altered the name to Gitchee Gumme in his poem and Gordon Lightfoot used that wording as well in his song
The Wreck of the Edmund Fitzgerald. For some reason I had that song in my head this morning.
"The legend lives on from the Chippewa on down
of the big lake they called "Gitche Gumee."
The lake, it is said, never gives up her dead
when the skies of November turn gloomy.
With a load of iron ore twenty-six thousand tons more
than the Edmund Fitzgerald weighed empty,
that good ship and true was a bone to be chewed
when the "Gales of November" came early."

The Edmund Fitzgerald sank that November, taking the lives of all twenty-nine crew members.
