I don't think so...
Maybe a freeborn GS seeker who trained with the Dragon Compromise trainees... When they needed fillers to "act" natural, freebiths were selected. Performances over brutal tactics and all that.
I for one, think almost ever clan selected a few Stars of freebirths to join, as we're taught that this is a clan infiltration unit. Sure Wolf sent the majority of people, but the training came from Goliath Scorpion and the mechs from various caches around the Home Worlds. I'll even bet Falcon, Bear, Raven, Adder and some prized, including Snord, individuals from the other clans were sent along.
TT
Edit: I just remembered something, most of the Infantry where a "fierce" force to fight, particularly 7th Kommado, Smoke Jaguar freebirths? Every Wolf Dragoon was from somewhere originally, we just don't have official numbers, per SOP of FASA/CGL.
