Tegan Jovanka's mother
From Tardis Wiki, the free Doctor Who reference
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)
