I think you are seeking the location and current owners of a particular farm near Koshkonong, Jefferson County, Wisconsin. Then you would contact the current owners re. their knowledge of any pioneer burial place on their farm. Is that right? Did Gulbrand have a relationship to a Vik family in 1854? If so, can you say more about them? No one named Vik or Viking shows up in the 1850 US federal census in Koshkonong, so perhaps instead you are referring to a farm that was owned by a Vik family in later times. Thanks in advance for additional information and clarifications.
