I forgot to say that you would need to post all that information even IF we tackled the whole giant group at once. No one can help you with "Ole Olson in Hedmark." That's like me asking you to find John Smith born in the Midwest. Hedmark is a big place with many cities, towns, villages, and parishes. The number of people named Ole Olson will be staggering. The birth year you cite may or may not be accurate (you don't tell the source, so one can't assess the credibility of your information) and that birth year is the only personal identifier you provide. People in Norway may or may not be found in public records with their patronymic name. Ole Olson could appear in the census as Ole Flom. Then if he moves his place name can change and he becomes Ole Tangen, for example. The difficulties of a search based on your query just go on and on. I am adding this note to clarify that additional information is needed from you whether or not you break up the line into smaller research chunks.
You might be hoping somebody already has this family tree completed and will write to you. But again, your query doesn't provide much that is distinctive to create a "hit" if somebody out there does an internet search such as a Google Search looking for other descendants of these people.
Again, to clarify, my words assume instead that you wish to actively research these ancestors yourself, rather than wait for someone else who has done so to show up.
Okay, enough. Just didn't think that was clear in my first post.
