Kimberly,
If you haven't already checked out family search, it has many records and genealogy listings that you may find helpful in your search. I found the following 1870 Census for Peter Hanson. His wife is listed as Sarah Hanson from Ireland, an Elizabeth Hanson, presumably their daughter and a Rose Higgins. There is a copy of the Census that you can print and FamilySearch.org is Free if you decide you'd like to have access to or create your genealogy records. If I can help you with anything else, please let me know.
