Dunbar

 is a new character who is added to Fallout 3 in the DLC Broken Steel.

He was a member of a group of ghouls who tried to make themselves a place to live in Old Olney Underground, assuming it would be an ideal place for ghouls to settle down since nobody ever goes there. The group set about knocking down some walls and apparently disturbed a group of Deathclaws. At the time the Lone Wanderer arrives, Dunbar is already dead.

His corpse holds Dunbar's Note, explaining the reason why the ghouls were in Old Olney.
