Joy Jovanka

Joy Jovanka was the mother of Tegan Jovanka and the daughter of Andrew Verney. At some point in her life, she was married to Tegan's father, William. (PROSE: Divided Loyalties)

When Kamelion tapped into Tegan's memories, he was overwhelmed by childhood memories of Tegan's parents and Aunt Vanessa, as well as the Fifth Doctor's memories of Gallifrey. (PROSE: Qualia)

Joy was still alive in 2006. (AUDIO: The Gathering)
