Help with a Norwegian surname

This is my 2nd great grandmother's marriage record in Osseo Wisconsin. Her name was Martha or Mathia Peterson and she was born in 1842 in Norway. I am trying to read what her father's last name could be-(2nd name to bottom of the page) but the handwriting is poor and the writer is using a lot of soundex and butchering the names. For instance 4th name to the bottom is supposed to be Orm Gullaugson and Ester Olson is supposed to be Astrl Eigildson. Peter's last name doesn't look like anything that I have heard before. Anyone care to take a stab at this one?
