looking for relatives last name KRZMPECK

My mother comes from Warsaw, Poland and her last name was KZRMPECK, given names KLARA, JULIA . She was born May 31, 1926. I know she had 12 brothers and sisters, but unfortunatly I can only recall one name and that is MARTHA. My mother came to Canada when she was just a teenager, and settled in Collingwood , Ontario. If anyone can help me with my search of family whom I have never met please send a reply. Even a reply to help me with how I can search names in Poland Thank you, Carol

Is it possible the name was Krzympek? That seems to flow more with the Polish language, but I could be wrong.

on here birth certificate it is spelt that way

The last name im looking for is not spelt KRZYMPEK........it is KRZMPECK.........i dont know why that changed from how i spelt it
