Knud Johansen 28 Sep 1845

[Joyce Fraser]

I have enquired under More og Romsdal, the birthplace of Knud Johansen, but since he 'went to Oslo as a young man' I wonder if someone would look up church records for a marriage, or even a death record, we know nothing of what happened to him.  Is there a index of emigration records?  He is on the 1865 census in Aure, More og Romsdal, but not on the 1900 census.  Is there an index for 1875 census, for Norway?  I have looked for him on the 1880/81 census for Canada and US, and not there either.
Help greatly appreciated.
