History

Formed in 1822 from St. Clair County and Oakland County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Saginaw County was created from St. Clair and Oakland counties and initially attached to Oakland for administrative and judicial purposes. Over the following decades, Saginaw was fully organized in 1835 and underwent numerous boundary changes, losing territory to the creation of Midland and Genesee counties, while temporarily holding judicial attachment to many surrounding counties including Arenac, Gladwin, Gratiot, Isabella, and Midland. By 1850, the county had largely taken its modern form, with Tuscola becoming fully organized and detached, and Midland remaining attached for judicial purposes into the 1850s.
