Thank you so much for the helpful suggestions and your quick reply--the link to the copper works looks very interesting.
I only have two other dates for him. He appears on the 1664 census for Tynset, so he had immigrated to Norway before that and he made a transaction for additional land at Smedeggen farm in 1685, so he was still living at that time. There is no parish record for Tynset for this time period, so there isn't an exact date for his entry into the parish and there is no record of his wife's name.
He had four sons: Rasmus b. 1657, Olluf b. 1659, Lars b. 1661, Pedar b. after 1666.
