History as far back as the third century is at best well educated supposition. The Romans were on their way out or already gone from most places. The indiginous celts and picts had no written language. As far as we can tell the 'viking' style longboats were used in raids on the coast of Britain from all over the place. I do not believe for one minute that the Irish were more adept at those raids than anyone else or that they took more slaves than others but it does seem to be taken as read that all races took their fair share of people in those raids. I believe it would be up to the revisionists to prove anything else. Not that this realy has any bearing on the subject in question!
