Anna Larsdtr. Olson b. Kvinnherad 1858

Hi, Anna was b. out of wedlock July 30. 1858 in Kvinnherad. Parents Ingeborg Johnsdt. Fedt and Lars Hanson Storegjerde. Anna grew up with her grand parents Hans Olson b.1810 and Anna Olson b. 1800. My Anna immigrated with her grandparents 1866. I do think they settled in Iowa. Her mother came in 1881 and is buried in Kvinnherred Cemetery, Calamus, Clinton. Don't think there has been any Connection. Her father immigrated 1862, he was b. february 9. 1838. I did find a Anna Olson who married a Jacob H. Jacobson in Story City January 5. 1921. Anna's parents was Lewis Olson and Isabelle Johnson. Could 1825 census tell us more? Thank you Magnar.
