Any information about Fettings in WI ?

My husband's father and his family came to Ellis Island (actually Fettingus- changed to Fetting) from war-torn Germany in the mid-forties.
The father may have been Wilhelm, the mother was Helena, sisters,Mata(pronounced May-ta) and Krista and my father-in law, Manfred. We believe that the sisters still reside in Wisconsin.Any infowould be helpful. Thanks!
