Who are the ancestors of the barbarians of ancient Europe?

I watched a show that led me to beleive that the Franks are the Modern Day French. England is a mixture of the Anglo-Saxons, and Normans. The Normans were basically the Vikings. What about the Huns? Visogoths? Vandals? Lombards etc etc etc... I am sure over time some of them ceased to exist and most of them absorbed with other races and dissapeared.
