Arneson Farms or Loberg Farms

Is there anyone that can help me find Loberg farms especially. I would really love to know where my ancestors came from. The furthest I go back is Oct 1859 for John A Loberg from Norway coming to the States around 1870/1871 according to all the census I found on him. This is my great-great grandfather. I have no other information other than death date and wife and children (which all happened in Minnesota). He came with his brother Edward and sister Bertha. His listed occupation was lathing houses. NOW, on the Arneson side. I do have quite a bit of information on them going back to about 1675, but, I'm greedy, I would like to try to find more about them. Knudt Arneson is my ggg-grandfather. He was born on Dec 8, 1834 in Innvik, died May 15, 1925 in Sparta, Minnesota. He married Anna Dorothea Jonsdtr Bye in Gaspe, Quebec. She was born on Jun 26, 1832 in Innvik, died on Jul 6, 1913 in Sparta, Chippewa, Minnesota. Can anyone help me[?][:I]
