After that legal defeat, Beaubien moved from the town of Chicago to a farm still in Cook County, Illinois near the portage to the Des Plaines River, what was then called "Hardscrabble" and later Chicago's Bridgeport neighborhood. Accounts differ as to whether he simply sold the lot he mad managed to purchase at the 1836 land sale, or was evicted from his remaining buildings in Chicago. The court also assessed legal costs against him for losing, which proved a financial problem for years. Some accounts indicate that Beaubien's farm from 1840-1850 was near that of his long-time metis friend and fellow trader Alexander Robinson, also on the Des Plaines river. Despite these legal troubles, in 1850, Beaubien received a militia commission with the title of "brigadier general". Command of the Illinois militia was later transferred to lieutenant colonel Seth Johnson. One historian indicates Beaubien remained on that farm for a decade, but moved to Chicago's West Side in 1855, as he married his fourth wife. One issue could be the expansion of Chicago's boundaries, as part of Robinson's farm was annexed to the city's West Side. All agree that Beaubien moved his family from Cook County to what became Naperville, Illinois in 1858, near the DuPage River in DuPage County. Beaubien died there at some time in January 1863 or 1864, survived by his fourth wife, as well as many children and grandchildren. He is buried with his third wife in his family's cemetery, established in 1845 in what became Lisle in DuPage County. The Chicago History Center has an 1825 portrait of Beaubien, as well as some of his papers which survived the Great Chicago Fire. A small Chicago street near the lakefront, "Beaubien Court" is named after the founder and gave access to the Illinois Central Railroad's freight warehouses. The downtown Chicago historical marker shown above was erected in 1937 as part of the centennial of Chicago's charter, The Chicago Public Schools named a north side elementary school to honor Beaubien. The Cook County Forest Preserve District named 279 acres with access to the Little Calumet River and the man-made 19 acre Flatfoot Lake on the south side near the Bishop Ford Freeway "Beaubien Woods."
