emigration/immigration for Andrine Johansdatter

I'm looking for emigration/immigration information for Andrine Johansdatter born to Johan Olsen and Maren Eriksdatter in Baerum in 1869. The last Norwegian record I see for this family is in 1875 Asker census listing them as residents at Vold Ovre. Also listed in this census is a brother Kristen. The first record I see in the US for her is when she married my great grandfather in Ramsey County, MN and she has the name Andrine Wold. The 1900 US census lists the year she immigrated as 1887 when she would have been 18 years of age. I have yet to find any documents confirming her departure from Norway or arrival in the US and I'm curious if she came alone or traveled with any of her family members. Can anyone help me locate these records?
