Anna R Weltzin?

I know, it looks more German than Norwegian, but that's what the death records for a couple of her children said. Anna was born (abt) Dec 1866, emigrated about 1877/1878. Her name on her death record showed Anna Victoria Michaelson. (I already have info on her husband, Jacob Matthias Mikkelsen). She died 17 Jan 1913 in Minnesota. I searched the passenger records on ancestry.com, but couldn't find anything. Can anyone help? Thank you!![:D]
