Actually, if you look in ANY decent book on The Celts you will find those same germanic tribes and many more smaller tribes identified as Celts. That's really pretty basic Celtic History.

Absolutely not. Celtic = Irish, Scots, Welsh, Cornish, Breton, etc.

Germanic = German, Danish, Gothic, Vandal, Frankish, Anglo-Saxon, etc.

Two distinct subfamilies of Indoeuropean and two distinct historical cultures are represented here.

Absolutely not. Celtic = Irish, Scots, Welsh, Cornish, Breton, etc.

Absolutely YES! You seem to come from an extremely sheltered historical background.

You are quoting the British version of Celtic history, a narrow and navel gazing perspective. You have to go the continent to get the whole story. The Celts didn't originate in Britain. Maybe you think The Celts, a pop group also are bastions of Celtic history??? Please locate a GOOD comprehensive book on the Celts, not some British screed, and find out what really happened.
