Why a town in mid-Michigan is named St. Louis

There is no river called the Mississippi anywhere near here, so the name takes some explaining. St. Louis, Michigan, sits on the little Pine River in the middle of the Lower Peninsula, about as far from the famous Missouri city as a Michigan town can be. The name came north anyway, and it came with the same man the whole county is named for.

The town itself started in 1853, when Joseph W. Clapp followed an old Indian trail to the Bethany Lutheran Indian Mission, then five years old, and decided to stay. He built the first house, and with other settlers he threw a dam and a sawmill across the Pine River — the standard way a Michigan town got going back then, with logs and water power. By 1865 the growing settlement had a name: St. Louis. Not for a saint directly, but for St. Louis, Missouri, where General Charles Gratiot had lived out the end of his life.

That is the quiet joke buried in the map. Gratiot County is named for Charles Gratiot, the Army engineer who built the fort up at Port Huron and never came anywhere near this farmland. And its second-largest town reached all the way to the Missouri city where that same man died to borrow its name. The county and the town point at the same person from two different directions.

Clapp’s mill town grew fast for its time and place, and the name stuck even as the sawmills gave way to mineral-spring resorts and, much later, to chemistry. But strip all that away and St. Louis, Michigan, is still a small river town wearing the borrowed name of a far bigger one, by way of a general who never saw either Pine River bank.
