Unadilla Township is a civil township in the southwest corner of Livingston County, Michigan, United States. The population was 3,333 at the 2020 census.[2]
There are no incorporated municipalities in the township. There are a few unincorporated communities and historic locales.
Unadilla was formed by an act of the Legislative Council of the Territory of Michigan on March 26, 1835, and initially included what is now Iosco Township to the north and a portion of Lyndon township in Washtenaw County on the south. The first township meeting was held on the first Monday of April 1835. Since Livingston County government was not organized until 1836, the township was at first attached to Washtenaw County. On March 6, 1838, Iosco Township was set off and with the southern portion being assigned to Lyndon Township, Unadilla assumed its present boundaries.
The first land purchase in the township was recorded on June 20, 1833, by Eli Ruggles of Brookfield, Connecticut, while accompanied by his brother-in-law, Amos Williams, and Nathaniel Noble, an acquaintance who lived nearby in Dexter. After returning to Connecticut, Ruggles became ill and died. Williams returned to the land in the fall of 1833 with his son Samuel, son-in-law Gary Briggs, and Briggs' wife. The land purchase was recorded as the north half of the northwest quarter of section 33, which would have been 80acres, but in subsequent accounts was frequently described as 40acres. During that winter the Williams and family built a sawmill, which began operations in the spring of 1834.
Unadilla Township occupies the southwest corner of Livingston County, bordered to the west by Ingham County and to the south by Washtenaw and Jackson counties. Two state highways pass through the township. M-36 crosses the center of the township, leading east 7miles to Pinckney and northwest to Dansville. M-106 has its northeastern terminus at M-36 in Gregory and leads southwest to Jackson.
According to the United States Census Bureau, the township has a total area of 89.9sqmi, of which 87.5km2 are land and 2.4km2, or 2.67%, are water.[4]
Lakelands Trail State Park passes through Unadilla Township.
