Genealogy / What region of poland is my family from? [27]

I want to know too but I am told our family surname is like Smith or Johnson in the United States? My grandfathers name was Swierczek and I guess there are tons and tons of them in Poland? All of the Ellis Island Swierzcek's or almost all of them are recorded as coming from Austria and I was always told that they may have originally been Austrian and not Polish, but everyone still says Polish? I am confused about it. If anyone knows more about this surname or can help me please email me!
