Susan was the granddaughter of the Doctor, the author of the first science fiction historical romance An Adventurer in Time and Space and other stories. She eventually served as Lady President of the Supreme Council of Gallifrey.
Her mother was the Doctor's daughter. By the time of her elevation to the presidency, she had two grandchildren of her own, a boy and a girl. She was the great-great-great-great-niece of Ordinal-General Quences. (NOTVALID: Auld Mortality)
She later ordered the Doctor to be captured as he was interfering with time. Zeuro failed to take the Doctor back to Gallifrey. She had spent most of her reign covering up the Doctor's interference but when the Supreme Council found out she had to order his execution. She wanted to show the Doctor the effects of his meddling.
