Anette Ringnes?

Hei! I am looking for my grandpa`s mother, born in Løten, Norway, 07.05.1882. She was baptized Agnethe Andersen Ringnes, but she may have left as Anette Ringnes, with the ship Montebello from Oslo, 07.10.1904. She left her two children, born 1901 and 1903, and maybe she left under false name since she "escaped". Her parents in Norway were Anders Olsen, born 1842 and Petrine Mikkelsdatter, born 1849, in Løten. Somenone said she was supposed to visit and live with her sister Oline Wilsen in Boston, but I don`t know if that is a true story. If someone has some information or guide me to where I could seek some more info..I would be happy :-) Greetings from Norway, Per Jakob Haugaa
