All of Beaulieu CLXXII, CLXXXVI & III are witnessed by one Rainulf and he is not the only witness shared between these documents; subsequent people appearing under this name seem likely to be a Castelnau follower, however, so I think these three are probably this one's only occurrences. He may be the father of Count Robert III of Turenne, however, in which case despite his minimal profile he is son of Count Godfrid I of Turenne and a comital scion himself, married to one Elisabet. All those details come from Deloche's work and are not present in any documents I've yet met.
