Gemma Teller Morrow

Katey Sagal stars as "Gemma," who is Jax's mother, a true matriarch. As fierce as she is nurturing, willing to go to any lengths to protect her family and domain, Gemma proves this once again when she murders Jax's wife, Tara, in a misguided effort to keep her son out of jail – adding to the wealth of dark secrets she already keeps.
