Reinsvold/Vestre Toten/Finstad Farm/Oppland

Can anyone tell me more about Reinsvold area? Looking for the Finstad Farm. Supposedly this is in Vestre Toten, Oppland. Trying to find information on my ggrandfather Johannes Iverson b. March 3, 1851/1858. Came to America in Dec 1873 or 1878. Settled in Fosston, Minnesota until his death in 1903. Any information would be appreciated. Debi Thanks. [email hidden]
