<P> Michigan's boundary with Illinois is formed by Lake Michigan, and three counties have water boundaries with Illinois: Berrien County, Van Buren County, and Allegan County . Michigan also has a boundary with Minnesota, which is formed by Lake Superior . The water boundary in this instance is formed by two counties: Ontonagon County and Keweenaw County . The land boundary with Wisconsin continues into Lake Superior, involving both Gogebic County (which shares a land border) and Ontonagon County (water boundary only). </P> <P> Nine counties have names invented by the ethnologist Henry Schoolcraft, usually adapted from parts of Native American words, but sometimes having parts from Greek, Arabic and Latin roots . Schoolcraft's made - up words have disputed sources . While he was a devotee of Native American words and culture, some of his words may have originated with tribes from other areas of the country, such as New York or the Northeast, where many settlers to Michigan came from . Real Native words were eradicated, and he substituted made - up words, sometimes with a kernel of Indian language or sound in them . </P> <P> A second group of four counties were renamed for Irish locales (counties Antrim, Clare, Roscommon and Wexford), apparently because it was close to the heart for certain Michigan legislators or their constituents . </P> <P> Ten counties, the so - called "cabinet counties", were named for persons who served in Andrew Jackson's presidential administration, which was tied to Michigan's anticipated ascendancy to statehood . Eight were named in 1829 . Livingston County was named in 1833 . Cass County was also named in 1829, but Governor Lewis Cass did not become a member of Jackson's Cabinet until 1831 . </P>
