Star Wars: Rebellion
Tiion Gama Sal-Solo is the mother of Thrackan Sal-Solo and the aunt of Ben Solo. Her husband, Randil Sal, died while Thrackan was still young. She is very reclusive, avoiding sentients to the point that all servants in her house on Tralus are droids. She is also unwilling to speak of her past, but there is some evidence that her family were, or claimed to be, direct heirs to the ancient Corellian kingship, and it seems that in her earliest childhood, her father Den Solo and her brother Jonash were abducted by pirates. Thrackan is known to be very protective of her.
