Strands and Reiakvam

My great grandfather was Ole R.(Rasmus) Strand b 2 Feb 1869 in Stranda, Norway. His parents were Rasmus Rasmusson and Lisa Ericksdatter. He married Oliana Sofia Andreasdotter Reiakvam born 8 June 1861 in Norway. They married on 2 Aug 1891 at Crow River Lutheran Church, Belgrade, Minnesota. They are both buried there. I am trying to find information on Ole's family. Can't locate his parents or siblings. Appreciate any help. Thanks, Darlene darlenepoppe
