Auðrósa and Jón emigrated west with her parents and siblings in 1883. They first lived in Helena, Montana, but moved to Spanish Fork in 1885 and lived there. The story goes that one reason was the hope that the prayers of the Mormon bishops could improve Auðrósa’s vision, as she was almost blind when she went west.
