Hitra Island - Hegersvik or Kornelius families

I am looking for any information on my great-grand-parents: Johan Hegersvik and Ingeborg Kornelius. They had a farm on Hitra sometime in the 1890s and moved to Throdheim later. I have not been able to find a farm with the name Hegersvik or Kornelius in that area. Does anyhone know of such? David Rothman Los Angeles, California
