The Jones family is a Maxis-made family that could be downloaded from the "Get Cool Stuff" section of the official The Sims website. The family should still be available from this page at The Sims 1 Depot, which has pictures of their house at 1 Sim Lane. The family consists of Edward Jones, Barbara Jones and Bobby Jones.
While players will often place this family in Neighborhood 1, it can be imported into any neighborhood.
Derived from "Son of John". Its use in the game probably refers to the idea of "keeping up with the Joneses".
