The first Europeans to come to the area were the French, who considered it to be part of New France. The French Jesuit, Roman Catholic priest, and missionary, Father Claude-Jean Allouez said the first Mass in Oconto on December 3, 1669. The Menominee living here began participating in the fur trade network and converting to Christianity. This area was included in the land ceded by the Menominee to the United States government in the 1836 Treaty of the Cedars. In this treaty, the Menominee ceded over four million acres of land after years of negotiations about how to accommodate the Oneida, Stockbridge-Munsee, and Brothertown peoples who were being removed from New York to Wisconsin. Following the treaty, the land became officially available for American settlement, although soldiers and lumberers had already been here for some time. The same year the Treaty of the Cedars was signed, George Lurwick bought a home and sawmill along the Oconto River, becoming the town's first private land owner now that the land had been sold to the United States.
