I came across the first names of 2 of my Norwegian 3x great grandmothers. * Jyri married Halvor Halvorsen. She lived and died in Norway, but their daughter, Bertha (born 1859) came to America in 1879. * Torgan (born 1832) came to America in 1840 and married Kittle Oleson some time before 1852. I am looking for the last names of Jyri and Torgan and I am hoping someone with access to Norwegian censuses can help. Thanks
