Re: Lassen / Lasson - family in Norway

I have some corrections to make concerning my last quest.
I now have this information. Reidar Olson was my grandfather who was born in Norway in 1881 and he married Bertine Lassen, I don't know when or where. Here is some information on Bertina Lassen. Born Bertine Caroline Lassen in 1853 (according to the 1865 census) in Kristiansund and the family lived in Ovre Elvegade Sparbu. Her Father was BERNT ANDREAS LASSEN and he was a baker by trade. Her mother was KAREN PEDERSDT.THis might help some one help me know when and where she married my great,greatgrandfather, Martin Olsen in Norway. They had a son named Reidar who was born on Oslo, Norway in 1881. The three of them came to America between 1881 and 1887 and had 5 more children born here in Gratiot Co. Michigan. Thanks again.
