C.J. Young

 is a young citizen of Rivet City. She often hangs out with her playmate James Hargrave. Her parents Christie Young and Henry Young also reside in Rivet City.

Unmarked quest: The Runaways
If you engage James Hargrave in conversation and bring up the issue about his equally problematic alcoholic mother, you can goad James into running away from home (uses Speech skill). If successful he runs away with C.J.; they can be found at Anacostia Crossing Station and be sent back home.
