History Channel's 'Vikings': Who's Who?
Earl Haraldson’s beautiful, enigmatic wife is much admired and performs her duties impeccably. Siggy (Jessalyn Gilsig) recognizes that her husband has a worthy opponent in Ragnar and encourages the earl’s efforts to best him. Siggy is fiercely protective of her daughter, Thyri, who is nearing marrying age. When it comes to her husband, however, Siggy may be less than loyal.
