<Tr> <Th> Relatives </Th> <Td> Nate Madock (father) Rose Madock (mother; deceased) Nathaniel Madock (brother; deceased) Tara Knowles (daughter - in - law; deceased) Abel Teller (grandson) Thomas Teller (grandson) </Td> </Tr> <P> Gemma Teller Morrow (née Madock), is a fictional character on the FX television series Sons of Anarchy, played by Katey Sagal . Gemma is the widow of John Teller, wife of Clay Morrow and mother of Jax Teller . She is unapologetic about the lengths she'll go to in order to protect the club, and is beloved by all of its members . She and Clay are arguably the series' main antagonists . </P> <P> Gemma was born November 18, 1957 to Nate and Rose and is a native of Charming, California; her maiden name is Madock . According to Sheriff Wayne Unser, she left Charming when she was sixteen and returned "ten years later with a baby and a motorcycle club". She married John Teller, a Vietnam War veteran and founder of the Sons of Anarchy Motorcycle Club, with whom she had two children: Jackson in 1978 and Thomas in 1984 . Gemma has a scar on her chest which is explained when her grandson Abel has surgery . Gemma has a genetic heart disorder from her mother's side which she passed on to her children - Thomas died in 1990 from complications of the disorder, and Abel nearly died from heart complications after his premature birth . After John was hit by a semi-truck and died in 1993, she quickly married John's friend Clay Morrow . </P> <P> Gemma Teller Morrow is the queen of Charming and the matriarch of the Sons of Anarchy . A Machiavellian schemer and expert in psychological manipulation, Gemma is extremely protective of her son and grandson, and she longs for the day when Jax will, in her eyes, be ready to assume control over SAMCRO to ensure the organization's survival for another generation . She adores her husband, Clay, and does her best to make things work out his way . Many of SAMCRO's plans succeed because of Gemma's quiet intervention (e.g., finding out who raped the little girl at the carnival in episode "Fun Town," and surveillance of L.O.A.N. in season two). She generally has a hostile attitude toward all of Jax's female friends and partners, including his ex-wife Wendy; his on - again, off - again girlfriend Tara (although Gemma later takes Tara under her wing); and the club "groupies" with whom he occasionally has sex . Her tough, but relatively classy, image includes hair highlights and a tattoo on her breast . Nord boss Ernest Darby has indicated that he had a prior romantic interest in her . She claims to be part Jewish "on the angry Russian side ." </P>
