Thorstein Pedersen and Elisabet Torrisdatter

I am trying to find decendents of Thorstein Pedersen (1813) and Elisabet Torrisdatter (1819) that might still live in Norway. In the 1865 Norway Census they were living in Hedmark in the Asnes area on a farm called Braaten. They married September 3, 1843. The children are Pernille Tostensdatter (this is the spelling I found on FamilySearch.org) born 1842 or 4, Thea Tostensdatter—1847, Ole Thornsteinsen—1851, Karn Torrisdatter 1854), Olina Thornsteinsdatter—1858, Kristiana Torrisdatter (1860), Thorstein Torrisen (1863). I know that Olina came to the USA in 1881 and eventually married. She was my husband's great grandmother. I did find the family still living on that farm in 1875 from information on Familysearch.org. If these names sound familiar to anyone or have an idea of how I can proceed on this, please let me know.
