Margaery Tyrell from A Storm of Swords is the granddaughter of Lady Olena Tyrell. Shortly after Margery's wedding to Joffrey, Lady Olena slips some poison into Joffrey's food and he dies. Since the marriage was not consumated, it is arranged that Margery will marry Prince Tommen (9 years old) instead. Margery cares about the people, but lives a double life. She is wildly promiscuous and has a particular fondness for musicians. She is as clever and cunning as her grandmother. She is a worthy match for Cersei Lannister.
