Renake (aka Jorgine) Hanson Parents

I have been unable to find the parents of Renake (aka Jorgine) Hanson. Hanson is her married name. Not sure what her maiden name is. She married Knut Hanson around 1865 and was born about 1833 in Norway, possibly Feb or May. It appears she and her husband immigrated in 1865 as well. Knut was born 17 May 1834 in Norway. Knut and Renake had four children (Hans, Anna, Laura and Clara) that I am aware of, all born in Jackson County, Wisconsin. Laura Hanson is my Great Grandmother.
