Betty Lynn Harley was the wife of Ed Harley who died under unknown circumstances before or soon after his son Billy was born. While Betty is not seen in the film or portrayed by an actress, her headstone can be seen when Ed goes to bury Billy's dead corpse after he is hit by a dirt bike by Joel, with Ed remarking "They killed our boy honey, now they're gonna pay.", referring to Pumpkinhead, the demon he had conjured to avenge Billy's death.
