I recall reading that the Celts never called themselves the Celts. As the Romans advanced farther north, the tribes and clans they encountered were all lumped in together called the "Keltoi." Just wondering who some of those tribes and clans were. Would the Gauls, Anglos, Saxons, etc be around this time period of the Roman invasion? I know the Iceni were, that was Boudica's tribe.
