Peder (Per) and Mariane Simons. Indrekvam

Can anyone give me some advice to find the parents of Peder (Per) and Mariane Simons. Indrekvam. I have found their marraige record on the Digitalarkivet. They were married 24 June 1872 in Sogn and Fjordane county. Groom's home parish Forde, groom home Botnen. I have also found their burial records: Peder 27 October 1912, birth year 1841, Marianne 9 November 1913, birth year 1838. I find them on the 1865 and 1900-telling, but I don't know how to find the names or other information about their parents.
