The Jones family are a premade playable family that can be found in Roaring Heights, a downloadable neighborhood from The Sims 3 Store. The family consists of single mother Beverly Jones and her two children Helen and Edward. Robert Jones, a Sim buried in the Roaring Heights cemetery, may be Helen and Edward's father, though this is speculative as he died of old age.
According to their family bio, Beverly is a fashion queen, Edward turns a blind eye towards fashion and all that Helen wants is some attention from Beverly.
This family shares their last name with three other families from The Sims Series. Any relation to the other families is unknown, and could just be a coincidence as 'Jones' is a common surname.
They may be spoofs of Joan Crawford and her two children, Christine and Christopher, respectively.
