Family of Gudbrand Ostensen Gammelsaether

I wish to find data clarifying the names and related info regardng the children of this couple, the first of which was Anne Marie, followed in order by Petrine, Ingvald, Elise, Mina, Martin (?), Olaf and Kristian, born from July 1879 to May 1900. I believe their place of residence, at least part of this time span, was Bjonevatn, Hadeland. Gudbrand's wife was Pauline Andreasdtr Furuseth, daughter of Andreas and Pernile..
