Twicherski on Family Tree Circles

I'm looking to find the parents of Paul Wicherski(1892?-) and Anna Wicherski(1903?-)(Unknown Maiden name). Paul came to the U.S. about 1913, Anna about 1914. I know Paul and Anna were born in Poland, and their parents too. Paul and Anna had 2 daughters a 1 son. Stephania Wicherski(1919-?)(spouse unknown)(children unknown), Josephine Wicherski(1923-2001)(spouse Edmund King)(children unknown)and Theodore Wicherski(1924-1986)(spouse Kathleen Fisher?)(children, 6 boys all living Wicherski's, Eric, Kevin, Brian, Thad, Terry, and Thomas.) Thomas is my father. I'm not sure if Paul and Anna changed the way their surname was spelled from something to Wicherski when they immigrated to the U.S. There are a ton of Wicherski's in the mid-west that i cant tie myself to. Any help would be greatly appreiciated. Thank you
