Maria P visit USA two times?

It would be great with some help on Anna Maria Persdotter, born 1872 May 12, Wermland Sweden. The story says she went to Grand Forks, Minnesota USA, two times. First trip must have been around 1892, when she was 19 or 20 years old. Maria got home sick and left but the people she visits in Grand Forks wanted her to come back and pay for a new ticket. When the second trip was made we don’t know. Logical she should have taken a boat from Norway. I can’t find any “Persdotter” but did find a Maria Person leaving Kristiania 26.02.1892. If this is “right” Maria, when should she arrive to USA? A relative says she went a month after her birthday. I did found 4 Maria Person on Ellis Island but not sure yet if I’m right. On one of them it says, Last place of Residence is Malnis, where is that? Does anyone know if there is any information on passenger list from USA to Europe? I receive different information from my relatives and that make me confused. In census from 1900 she is back home again and for good. If someone could help me I would be more then glad.
