You are welcome! I'll go back and look at the tree to see if there's more I can add to what I already posted. I recall it said that Ole Christian Larsen was born 1866 in Norway (no specific place) and had a father Lars P Larsen, no dates, no locations, and a mother Louise Olsen, no dates, no locations. If that's not your tree, then probably the most interesting thing about it is that you may have a cousin working on this genealogy! You can get a free Ancestry subscription for a couple weeks I think, and that would enable you to write to the tree creator.
Previously we found Severin Olsen born 23 July 1871 in Sarpsborg.

A similar family tree is posted on Family Search. Also has Victoria born 03 March and other similar quirks, so likely same tree creator, or it could be.
