Let us not forget the part Geillis Duncan played in Outlander.
She is the wife of the procurator fiscal, Arthur Duncan, and lives in Cranesmuir, a village near Castle Leoch. She befriends Claire and shares her passion for herbs. She is charming, beguiling, and mysterious. She is willing to do whatever it takes to further the Jacobite cause.
She also has this wicked giggle that leads one to believe she is always up to something!
