How Allendale ended up named for Ethan Allen's daughter-in-law

The name on the township sign hides a thread that runs all the way back to the Green Mountain Boys. Allendale, the booming college town west of Grand Rapids, was named for Agnes Allen — and Agnes was the widow of Hannibal Allen, who was a son of Ethan Allen, the Vermont firebrand who helped seize Fort Ticonderoga in the opening weeks of the Revolutionary War.

Agnes never had to do much to land the honor. When settlers organized the township in 1849, her name simply sat at the top of the tax roll — the first name on the list of who owed the new government money. That alone might not have made the maps. But the petition went to the state legislature through Senator Henry Pennoyer of Grand Haven, who took it upon himself to swap in a new name, drawing on Agnes Allen. He even spelled it wrong at first, “Allandale,” before it settled into Allendale.

So the town carries a borrowed bit of national history almost by accident. Hannibal Allen himself never lived here; he was an Army captain, born in Vermont, who died of yellow fever in Virginia in 1813, long before any of this. The connection to his famous father came west only as a name attached to a widow’s tax bill, and a senator’s whim turned it into geography.

The first people on this ground predate all of that. A French fur trader, Pierre Constant, set up a post along the Grand River around 1810, and the first lasting settler, a Welshman named Richard Roberts, built a cabin in 1842 that travelers knew as the Half-way House, with a sawmill and a store beside it.

Generations of Grand Valley State students now live in a township named, through a chain of widows and senators, for a Vermont revolutionary who never saw Michigan.
