Brede E Molstad, Maria Melbostad boat records

Hi. I'm looking for boat records for Brede E Molstad and Maria Melbostad, both from Gran, Norway. I'm not sure if they were married when they came over or if they came together. Some notes suggest Maria came over in 1865 and stayed with her brother, Gunder in Houston County, MN. Brede might of traveled with his brother, Gunder.. Brede and Maria were married at some point and had their first child, Kjerste, in 1869 in Fillmore County, MN. Thank you for any info you can find.
