First in were the Gaels (Irish) through Skandinavia, then the Icenii Brythonics (which is where 'Briton' and then 'Britain' came from) and some lesser tribes, such as the Manx. But none of these spoke German, either high, middle or low. Germany as a territory was defined later. The term 'Germanic' is a term applied later to describe the general area of issue, but it is only approximate, Czechoslovakian would be just as appropriate.
not sure what you mean but: 'germanic' is at least somewhat relevant, (former) czechoslovakia on the other hand is completely different beast (inhabited (mostly) by slavic people (czechs and slovaks))
