At some point in her life Lissa married Aaron Wrayburn and had two children with him, Aria and David. When Lissa found out that David was actually a woman, she allowed her to be herself at home, though she asked that she "be David" in public.
When David was injured and Aria killed in Thailand following a fight with revenants, Lissa and her husband falsely reported to the Clave that David had died instead so that she could live as a woman, with the world thinking her dead.
David, now Diana, spent three years living in Thailand and transitioning. During this time Lissa and Aaron often suggested clandestine visits to Bangkok for their daughter, which she refused as she didn't want to get them into trouble.
Lissa was a caring and accepting person.
Lissa loved her son very much, and did her best to accommodate his feelings and protect his secret from the Clave.
