I allow to re-quote the first post:

When we are talking about a "Roman" cemetary of the 4th Century AD we have set straight before what is considered to be Roman in this periode. We have millions "Romans" living north of the Alps that did not even come close to Italy in all their live. We have a full migration going on along all of the Rhine with masses of Germanic crossing the border peacefully and setteling on Roman lands.

On the other side of the border there were large parts of the land living for centuries in very close contact with the superior Roman culture. And there was also always large movements going on within the Germanic population that effected their entire area of living.

And we have, of course, the hughe number of Germanic mercenaries that served for the Romans, and became more or less Romanized.

That means:

- It would be more or less impossible to distinguish a Germanic (for example a warlord or a trader) of the 4th Cent. who has lived all his live in Denmark but collected a lot of Roman stuff for some reason from a Germanic (for example a mercenary or trader) who was born in Cologne or Treverorum and happened to die in Denmark for what reason ever simply by the content of his grave.

- It is absurde to assume that, given the hughe number of Germanics that were living in the Roman Empire, the Romans didn't know a lot of details on Northern Europe. That is just random of the remaints, considering how few writen sources have survived at all.
