[1] Peder Ivarsen was born on the Undi farm in Vik, Sogn og Fjordane, Norway.
Peder Ivarson, together with his wife and their children, became the first emigrants to the United States from the Sogn og Fjordane county in Norway.
Per Undi had also been influenced by Ole Rynning's True Account of America (Norwegian: Sandfærdig Beretning om Amerika) which was published during 1838.
The family settled in Wayne Township near the community of Wiota, known in its early history as Hamilton's Diggings in Lafayette County, Wisconsin.
Resulting from his efforts of persuasion, numerous families immigrated to Wisconsin including his siblings: Ragnilda, Erik, Ole and Axel Iverson.
