I m looking into the profile of Carl August. Do you have any topographic info? Where he was born, passed away, lived?
I think I found the marriage of the daughter Edith V. Carlson in Iowa.
Father named Carl August Carlson, mother Anna Anderson.
According to the transcription Edith was born in Sweden. Marrying Edward Thomas Fortune in 1916-11-01 in Boone, Boone, Iowa.
You are asking for info on a (Jo)hanna Anderson. If the named transcription above fits Johanna might be named Anna in the US.
At the profile of Carl there is a spouse named Hilda Johannson. Did he remarry?
Any info can help me to find records please.
