Rolfsmith -- could even be as far out an idea as she was Mrs. Rolf Smith or Wid. Rolf Smith (Ralf or Ralph) and over time/transcription it got smooshed. Old marriages sometimes referred to a widow by reference to her previous husband instead of her OWN name. Note: sometimes a name gets so messed up, you just have to search on a first name... Or just start scroll thru all records....
