At some point in his life Aaron married Lissa Wrayburn and had two children with her, Aria and David. When Aaron found out that David was actually a woman, he allowed her to be herself at home, though he asked that she "be David" in public.
When David was injured and Aria killed in Thailand following a fight with revenants, Aaron and his wife 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 Aaron and Lissa often suggested clandestine visits to Bangkok for their daughter, which she refused as she didn't want to get them into trouble.
Aaron loved his son very much and tried to accommodate his feelings and let him live the life he wanted to.
- Aaron always kept the bathroom of his apartment above Diana's Arrow stocked with bandages.
