I have information on her parents coming to the US as well as her brothers Moses, Joseph, Alfred and Gilbert. I am sure it won't be difficult to locate a record of Baptist and Marguerite coming to the States. The 1870 US Census shows them in Plover, Portage, Wisconsin. They are also in the 1880 US Census in the same location.
I have her burial place and picture of her headstone.
