Edited post: I just merged my profile for Jørgen with the existing profile managed by Torbjørn.
DNA strongly suggests that Jørgen is the father of my mother Hjørdis Olsen Paulsen. Jørgen's grandson Knut (via Astrid and Marit) shares 5% and 316 cM DNA with me and my twin brother. My mother was born in 1924 well before Jørgen married Astrid.
I welcome discussion on this as it probably comes as a surprise to relatives.
