I am looking for other researchers who know of this person's family. He was born 16 Mar 1834 to Nils Gunbjornsen or Gunbiornsen and Berit Helgesdatter. He married Torgun Nielsdatter (born in Rollag) 17 May 1858. He was in Winneshiek County, Iowa by 1860 and later in Ottertail County, Minnesota. Where is the farm Qverna or Kverna, a name he also used in the US?
