Ruth is an unincorporated community in Sherman Township, Huron County, Michigan. The ZIP code is 48470. The first white settler was John Hunsanger, a native of Hadhomor, Nassau, Germany, who arrived there in 1855. The following year, several families from Baden joined him, and in the early 1860s, another group arrived from Westphalia. The area became known as the German Settlement. It was also called Adams Corners for landowner August H. Adams, who served as the first postmaster. But when the village got a post office in October 1880, it was named Ruth, after Michael Ruth who had given property for a railroad depot.
