ANDRZYCKI Surname and Looking for info on Antonia Agata Andrzycki and Family

Hi there - I am researching my family tree which includes the family name ANDRZYCKI.Antonia Agata Andrzycki was my grandmother's name (maiden).She was born in Wanne-Eickel, Germany on February 9, 1901, but her family hailed from the Katowice/Krakau area.They were coal miners.Possibly some Jewish/Russian heritage in there as well.As far as I can tell ANDRZYCKI seems to be a rather uncommon or rare name as after several years of research have yet to come across it in databases, records etc.PLEASE, any info at all appreciated!Thanks again, Moka:)
