There is no such thing as "Norwegian noble families" today. Some members of one of the two Treschow families in Norway were untitled nobles for a few years after 1812, but no families are considered noble in Norway today. The entire family was not noble, only the patrilineal descendants of Michael Treschow including unmarried females according to Danish law, but not according to Norwegian law since 1821. None of those who today inhabit Fritzøehus are noble by Danish law. The most famous member of either Treschow family was Niels Treschow, who was unrelated to Michael Treschow's family and who was not noble. The term "family seat" has no legal meaning in Norway today and is misleading, Fritøzehus, completed in 1898, is today inhabited by Stein Erik Hagen and Mille-Marie Treschow, and will presumably be inherited by a member of the (un-noble) Stang family at some point. Fritøzehus has never been a family seat (setegård) in the legal sense, as the term became obsolete long before Fritzøehus was built. TuriTerj (talk) 20:49, 17 June 2011 (UTC)
