I noticed that too, looks like the woman portrait was sold at Christies on 2014. https://www.christies.com/lot/cornelis-de-vos-hulst-c-1584-1...
And the provenance says the painting has been in the present owner's family since 19th century, maybe there is some clue on the family.
That forms a fashion connection or memory to the (maybe) danish noble/upper class people in the portrait in the story.
