This 1851 map of Northeast Illinois counties marks the boundaries of the “Archange Ouilmette Reserve” within New Trier Township. Archange and Antoine Ouilmette left the Reserve in 1838 and passed away in 1840 and 1841, respectively. But it was not until 1871 that all eight of their children sold their interest in the land that would become Wilmette, with the requisite approval of the President of the United States.
See the full map pictured above, and learn much more about the Ouilmette family by attending the opening of “The Ouilmettes: A Retelling” during our Open House! Sunday, May 4, from 11am to 2pm.
