Lady Cinowyn is the stepdaughter of Captain Raymus Antilles of Tantive IV, murdered by Darth Vader when the ship was captured. Her mother, Lady RiSanne, was an Aldaraanian courtier who had grown up offworld and returned to her homeworld shortly after the end of the Clone Wars, pregnant by her late husband, a GAR medical officer. RiSanne never spoke about her past. This, RiSanne's martial arts talent, and the fact that the late Queen Breha had made a place for her at court, led Cinowyn and her next-oldest (half-)brother, Trevor, to speculate among themselves that RiSanne had been an Aldaraanian or Republic agent during the Clone Wars.
