City in Illinois whose name comes from an Algonquin word meaning garlic Field?

No city in Illinois has a name from Algonquin - that language is only spoken by the Algonquin tribe of Canada. Chicago is named from the Miami (not Algonquin) Word chicagoua, meaning the wild native garlic plant (Allium tricoccum) - there is nothing in the Word that represents "field", so it definitely does not mean "garlic field", simply "wild garlic".

It is claimed that the Miami Word also signifies "skunk", but this is given as shikakwa in modern sources.
