Lucretia Johansdotter Gyllenhielm (1561–1585), was the illegitimate daughter of John III of Sweden and Karin Hansdotter.
She was betrothed to the nobleman Karl Gustafsson Stenbock.
[5] Karl Gustafsson Stenbock accused the noblewoman Kerstin Gabrielsdotter Ulfsax, wife of Joen Nilsson (1536-1600).
She was rumored to have murdered her late spouse and of having bewitched Lucretia.
[6][7] Ulfsax was arrested, and after having failed to collect twelve female nobles as character witnesses, she was executed.
