Bernt and Magnus Hansen

I am trying to find record of my great great grandfather, Bernt Hansen, and his brother, Magnus C. Hansen, in Norway. I don't know where in Norway they are from. They emigrated from Norway to London, England and set sail on the S.S. Thames (1) of the Temperley Line out of London on July 19, 1865 and arrived in Quebec August 4th. They both settled and farmed in Rolling Fork, Pope County, Minnesota. I believe their father was Hans Borreson, but I don't know for sure. I appreciate any help! Thank you. Eric Andersen
