there are theoretically loads of chapters that have turned from the Emperor's light (bare in mind though its illegal for SM to not pay at least lip service to the Big-E, so if you don't, then you are no friend to the Imperium). however, tracking down specific names and details is a bit harder. any of the groups mentioned in the Codex: CSM that are not a faction of one of the Traitor Legions will have been a Chapter and will have been equipped as such. so there is no harm in using the C: SM to represent them. in fact, it used to be the case that the codex for Chaos only represented Legions, as it was assumed that anyone less ancient would not have managed to attract daemons or accrue daemonic artifacts.
