The story is the most famous of all Swedish legends about ghosts, white ladies and black wives who haunted castles and manors.
This meant that many men were absent serving in warfare abroad, and the responsibility of their estates in Sweden fell upon their wives who were left behind at home.
The perhaps most known one was a song named Pintorpa-frun, which were written by the poet Wilhelm von Braun and widely spread by Broadside (music) during the 19th century.
Beata von Yxkull married the owner of Pintorp in 1636, and managed the estate during the absence of her spouse and after his death in 1657.
Anna Oxenstierna was pointed out as Pintorpafrun in the famous song by Wilhelm von Braun, but in fact, she had no connection to the Pintorp estate.
