Iver Iverson b: 1823 -Gr. gr. father- help needed

I am searching for my grt grand parents Iver Iverson and Berthe Maria Andersdatter records in Norway. They were both born approx. 1823 and came from Solar Osterdalen Norway. They came to the U.S. in 1865 and settled in Minnesota. I found an Iver Iverson confirmation record in Hof church book in 1839 on pg 1084. He was 16 yrs old. I am unable to locate him at a later date to see if I can connect him to a marriage to Berthe Maria or if this may or may not be my gr. grandfather. Any help would be very much appreciated.
