Bio: The widowed matriarch of the Barkley family of Stockton, California, Victoria Barkley was the active leader of her clan. She is the active manager of the family's generally prosperous cattle farm.
She is the mother of Jarrod, Nick and Audra.
She is not the mother (or even step-mother) of Heath, the alleged illegitimate child of her dead husband. Victoria only meets Heath for the first time in the series pilot. In the "Big Valley-verse", Heath comes to live with the Barkleys as an adult—only after both his father and mother are dead. As a result, his claim to any status with the Barkley family can only be verified through the hearsay of the villagers in his mother's hometown.
Despite the lack of legal force, however, she eventually treats Heath as a son and he largely respects her as a parent and boss.
