Who are Conrad Knutsen Bye and wife Randine

Conrad K Bye and wife Randine are first found in the 1900 US Census. Daughter Christina was born in Norway. I have a lot of information on this family in America but can not trace them back to Norway. Any help will be appreciated. The middle name of Knutsen may be speculative.
