I very nice, and different, view of "borgen". I saw a comment at the end of this session, asking for details about Elisabeth Eitzen. If I recall right, Asbjørn Montelius who lived at "borgen", married her and moved to her family's farm close to Næringsrød. Perhaps you have answered Lindesey? Anyhow, thank you for the surprising angle of "borgen" and Gamle Sørhaugen.
