Genealogy / THE MEANING AND RESEARCH OF MY POLISH LAST NAME, SURNAME? [4500]

trying to look for info mainly on Snopkowski I hear the root of this name was snopek from my husband's grandfather. looking for Krostuj, Skiba, and Skowronski also though.

all my husband's grandfather's grandparents Adam Skiba and Kathryn Krostuj immigrated from Crakow. I don't know though were Carolina Skowronski or her husband a Snopkowski ( I don't have his first name) came from. I am still trying to figure out were they were in Poland
