Most of Au Gres Township was built recently: 9% of its homes predate 1940 and the median home dates from 1981. Below: maps from 1966 on and the census since 1910.
French explorers named the location Point Au Grès; grès means "gritty stone" or "sandstone," from which the river and the town take their names. It was first settled in 1862 temporarily by workers on the Saginaw–Au Sable State Road. The first permanent settler was John Edward Bradley, who built the Bradley House in 1866. On August 8, 1867, the location, which was still a part of Bay County, was granted a post office with Bradley as the first postmaster. The post office was closed from March 2, 1874 until April 30, 1874.
