The younger sister of actress Vera Farmiga, 17-year-old Taissa only has one credit to her name going into this FX series: playing a younger version of her sister's character in Vera's directorial debut, 'Higher Ground,' which got a lot of buzz at Sundance this year. Now she's acting alongside an all-star cast, including Connie Britton, Dylan McDermott and Jessica Lange.
