That isn't enough info. Possibly -- Maybe if we knew who Marthe married it would help. Did she or they emigrate? To where? When? There are three people by the name of Bergen in all of Norway in 1801 and only 2 in 1865. Where did you find that name?
I would try putting a little more effort into your post and you may find a volunteer who can help you. The more info you put "out there" the great chance you have that it will trigger someone's response.
