History
Formed in 1879 from Oconto County
An old deed may name a county that no longer exists, or a boundary that has since moved.
Marinette County was created from Oconto County on March 3, 1879, and was named after Marinette Chevalier. On April 1, 1882, Marinette lost territory to the creation of Florence County, which included the portion of Oconto that had been transferred to Marinette on the same day.
