The home of Archange (Potawatomi) and Antoine Ouilmette was one of many French and Native households in early Chicago. French and American men frequently married Native women as a way of integrating themselves into existing kinship networks, and Native women expanded the connections of their own kin through these marriages. Archange was the daughter of Marianne (Potawatomi) and François Chevalier and the granddaughter of Potawatomi leader Naunongee, which meant she was connected to one of the most notable Indigenous and fur trade families in the western Great Lakes.

Though we don’t know very much about the Ouilmette home other than that it neighbored the Kinzie house, we can make educated assumptions about Archange based on what we know about other relationships between French men and Native women. Archange likely served as a translator for her husband Antoine, instructed him on Native protocols, and was his way of integrating into existing Indigenous kinship networks. Many believe Archange was instrumental in helping settlers navigate the constantly fluctuating portage between the Chicago and Des Plaines River. Though the business of leading people through the portage was in her husband’s name, she would have carried that knowledge of the land from generations of Potawatomi people who lived around and used the portage before her. We also know that Archange helped several of the wives of officers at Fort Dearborn through pregnancies and deliveries, and that she personally helped survivors of the Battle of Fort Dearborn to survive in her house by disguising them as Native women. She and her husband worked directly with Indian Agent Alexander Wolcott to acquire support for the Treaty of Chicago in 1833. In the 1829 Treaty of Prairie du Chien, she and her children were given a plot of land on the Northern border of the city that includes parts of the present-day cities Evanston and Wilmette. The Village of Wilmette is named after her family.
