Raymond Marr, the son of Kila Marr, was born in 2322 and died in 2338 at the age of sixteen. When his mother left the colony to pursue her career, she placed him in the care of the Wallace family. His girlfriend was Janina.
He was nicknamed "Renny". He lived at the colony on Omicron Theta and he died on the planet when it was attacked by the Crystalline Entity. He kept journals, and he enjoyed playing parrises squares despite his mother's worry about the sport. He was having trouble getting his mind around the study of cell biology. Many of his thoughts and memories were stored inside of Data. (TNG: "Silicon Avatar")
Raymond Marr was voiced by Jason Marsden who received no credit for this voice part.
