Looking for family info on John Johnson Storoien

I am trying to figure out some family info on my great-great-great grandfather's family. My great-great grandfather's name was Peter Johnson and he was born August 21, 1859. His parents were John Johnson Storoien and Marit Staaloien. John born: May 26, 1825 and died: February 07, 1898. Marit born: September 13, 1824 and died: February 07, 1907. I know that Peter had one brother John Johnsen Storoien born in 1848. I am wondering if there were any other children in this family. They came and homesteaded in Osakis, MN in about the 1870's I think (not sure). Any help would be great! Thanks! One other thing I will mention is that John Johnson Storoien parents were John Olsen Stokke born: 1785 and died: 1874 and Anne Gilsaamo born: 1782 and died: 1856. Don't know if this will help, but I thought I would add it anyways! Thanks!
