You may want to stop by the ARC in Platteville on Sunday afternoon, they are open on Sundays. This is where you would find older naturalization records. http://www.shsw.wisc.edu/archives/arcnet/index.html http://www.shsw.wisc.edu/archives/arcnet/plattvil.html http://vms.www.uwplatt.edu/~swwis/ Their card catalog is also on-line. For library material use the Platteville Karrmann Library card catalog. http://www.uwplatt.edu/~library/ For archival items use the ArCat catalog http://www.shsw.wisc.edu/archives/arcat.html ... limit your search to Platteville ARC if you wish.
