Jerr's list is definately not complete.. and the question here is specifically about NPCs from BG1 (whom you don't necessarily meet in the game)
Here goes:
Faldorn: seized control of the druid grove.
Xzar and Montaron: get killed by Harpers (M while breaking into compound, X by an assasin later on)
Quayle: In the circus.
Safana: tries to kill you in one of the after-underdark forest area. Related to Coran and warewolves.
Also lets not forget:
Branwen and Xan: found in tutorial
you can also CLUA in Kivan. though he says nothing. Maybe he was initially supposed to be used somewhere but then was dropped.
EDIT: by the dwarves you mean Korgan? I mistook him for Kagain initially. But they are different.
