I suggest using BaSIA
http://www.basia.famula.pl/en/ to help with your research. It has the marriage record for Kasimir and Jadwiga including their parents and the birth records for three of their children born in Poland. BaSIA provides a link to the archives so you can obtain the actual record images.
