The documents you have were issued in Poland or elsewhere? Are they printed or hanwritten? There are four Kalisz in present-day Poland territory. If the name in your document was misspelled, I guess it could be Grodziec, 20 miles North of Kalisz and south of Konin. Or Grudzielec, 12 miles West of Kalisz. What was his first name? Have you already checked the Poznan Project in http://poznan-project.psnc.pl/http://poznan-project.psnc.pl/ ?
