Ena Gilbert born Norway 22 feb 1851

I am looking for information on Ena Gilbert. She first appears in Minnesota, Goodhue County when she married George Kelly in Red Wing Minnesota on 3 July 1869. Her marriage announcement says she was from Minneola. Some census’s list her year of immigration as 1869 (1900 census) others as 1853 (1930 census while living in a nursing home). Ena and George several children including a daughter named Clara Beryl. Beryl appears to be a family name of some kind. On Ena Gilbert Kelly’s death certificate it gives her mothers name as Ena (no last name) and father (no first name) Gilbert. I have not been able to locate any information in Minnesota to help identify her place of origin in Norway. I have tried tracing her descendents to no avail also. Any ideas/suggestions appreciated.
