I think we are researching the same people.
From "Crossing Paths," a family history project put together through interviews with grandparents, I have:
"Hans Erikson and his wife Jorgin Petersdaughter, immigrated to America from Norway with their adopted niece Caroline Quale. They came over on a small boat. As they were crossing, they were engulfed by a storm, which blew them off course. Consequently, their voyage took 13 weeks. Finally they landed in New York. In 1868, they arrived in Winnebago County, Wisconsin; in 1970, they went to Chetek Wisconsin. Hans Erickson was a shoemaker and farmer."
I have not independently verified any of this, as I am just starting on this branch of the family.
I have also just started a blog. http://unravelinghistorymysteries.blogspot.com/
