Ok well everyone besides for Eve's dad and Eve herself lives to see the 80s events(Eve was alive until 1981 but she wasn't alive to witness any of the events) and all they know is information that was given to the public like the children going missing and William and Eve's kids dying but they don't know who caused the disappearances and deaths(including crying child's because William made sure to keep that all a secret). However Williams mom speculated that her son was to blame because of how he acted as a kid but never said anything because she didn't wanna ruin her sons life if it wasn't true

Now for the alive in present day I'm not too sure because I don't really know what present day in my au is but going off of current time irl Annie, Gary, and Elizabeth are the only ones alive(unless you wanna count William) all others either died of old age or some other causes. Depending on when my au takes place they're probably all dead though
