According to Chapman's History of Washtenaw County (1881), the legislative Council of Michigan Territory defined the boundaries of Washtenaw County in 1822. Washtenaw is a variant of Wash-ten-ong, a Chippewa name for Grand River. The Huron River valley was originally home to a large Native American population. In 1680, the French explorer LaSalle passed eastward through this region canoeing from Portage Lake down the Huron to Lake Erie. French fur traders and Jesuit missionaries soon followed.
