Hanna Nilsdatter born 1835 in Skien daugher of Nils Nilsen

[dn24919]

I am looking for the parents of Hanna Nilsdatter, born 1835 (according to census records) in Skien, daughter of Nils Nilsen, according to her marriage certificate. She had a sister Mary born in 1837 in Skien.

Hannah and her sister Mary immigrated to Hartlepool, Durham, England between 1852 and 1861. Hannah married John Whelpdale on July 28, 1861 in Durham, England. Hannah died Feb 17, 1891 in Hartlepool, Durham, England. She had several children.

My question is who were Hannah's parents, knowing her sister's name, father's name, date and place of birth?
