I have been looking for relatives of my great great grandfather Carl Anderson, and his brothers Christian and Hans, in the Audubon area in the late 1800’s. I have recently discovered their sister, Maren Sofie Anderson, lived there too from 1882 until she died in 1919. She was married to Peter Christian Berger, and had four daughters, Lena, Thora, Anna, and Clara. The surnames of the descendants I am looking for from their marriages are: Hendrickson Brenden Elton Johnson and Hein. I believe many of them still live in the Audubon / Detroit Lakes Area.
