Bertha Marie Andersdatter Iverson

Looking for help to find any info: birth records, marriage records emigration info on my Grt Gr Bertha (Berte) Marie Andersdatter born 5/20/1824 or 1825 in Solor Osterdalen Norway. That is the only location I have for her birth. I have been searching the Digital Archives under Hedmark County for a long time and find nothing. She married Iver Iverson in Norway, had a daughter, Johanna born 12/29/1856 in Sole?? Norway. They came to US in September 1865. Any info would be greatly appreciated.
