The Soundex Index to Naturalization Petitions for the U.S. District and Circuit Courts, Northern District of Illinois, and Immigration and Naturalization Service, District 9, 1840-1950 (NARA film M1285) covers naturalizations filed from 1871-1950 in Federal courts in Chicago and from 1840-1950 in Federal courts in Danville and Peoria, IL; Hammond, IN; and Madison and Milwaukee, as well as county courts in eastern Iowa; northwestern Indiana; eastern Wisconsin; and northern Illinois.
