I saw your message and had just been doing some stuff on my grandfather who was frok Mosvik. I still have 2nd cousins in Mosvik and a cousing in Levanger. I ran across a data base of people who left Mosvik for Amerika and the following Grande is listed : 28.05.1902 Lovise Grande age 37 from Mosviken with destination Halstad, Minn sailing with the Stjerne line on the Tasso (this ship would have taken her to Hull, England, then probably by train to Liverpool) with a ticket to America.
Don't know if this is of interest but thought I would pass it along
