Hi Jacob,
It's been a while since you posted, so hope this reaches you. I too am trying to research a John Aune who (according to 1900-1920 census records and his death record in Lincoln Co, Minn) was born March 1859 in Norway. in 1900, is mother, Bertha b. Jan 1823 Norway, is living with his family.

John married abt 1890 to Carrie J. Knutson (her parentage is unknown at this time. I havge 6 children and several grandchildren listed for John and Carrie (from the census records and birth and death records of Lincoln Co, MN.

In the 1910 and 1920 census enumerations, John states that he immigrated in 1881.

Is it possible we are looking for the same John Aune?

Thanks,
Kay
