Good day! I came across your post while searching the lineage of my grandmother - Esther Engebretsen - daughter of Maren & Karl Engebretsen born 1892 in Skein - later married to my grandfather Joseph August Thompson of Farsund.
I do not have any information on the Olsen connection. Sorry. Do you have any information on the lineage of Maren & Karl Engebretsen?
