I am researching this couple. They married in Volga, Dakota Territory in 1880 or1881, and appear in 1900 census for Brookings County with several children. I am looking for anyone who ties into this line or has any information on the family. John was born in Norway and died in 1907 from working in the mines, and was buried in Deadwood, South Dakota. I am having trouble finding proof of his immigration and the names of his parents. I have had more luck with Caroline as she lived until 1930.
