I am interested in the name Ahlstrom. Particularly in Fena C. Ahlstrom. She was born c1880 in Sweden, married (1) a Johnson, and had the following Johnson children in Minnesota: Harry F., Agnes A., James A., Walter Herbert, and a baby who apparently died young.
Her second marriage was to Charles Swanson and had the following children by him in Minnesota: Violet, Hazel (my main interest), Curtis and Vivian. All these people are listed in the 1910, 1920 and 1930 census records of Blue Earth County, Minnesota.
