They were the parents of Inger-Helvig Ødegaard Paus, who married barrister and employer representative Jens Christian Rogstad, surgeon, humanitarian and Grand Master of the Norwegian Order of Freemasons Bernhard Paus, who married humanitarian Brita Collett, and barrister, diplomat and managing director of Press Paper, Ltd. in London Vilhelm Paus, who married Anne Collett.
