Oborski family of Nanticoke, PA

I am trying to locate information on my grandfather's family (Clemence Carl Oborski (I) and his wife Rita Marie Dorris/Doris)who settled in the Nanticoke, Pennsylvania area.The Oborski family originated from Posen, Poland and settled in Pennsylvania prior to the turn of the century.Because of Hurricane Agnes that stuck the area in June of 1972, many of the church and family records were destroyed.
Please help!
