Scandinavia and the Germanic tribes such as Goths, Vandals, Angli an

With interests I read messages about the Scandinavian origin of the
Germanic tribes such a Goths, Vandals. But who did read "Skandinavien
und die Gothen" written by Rolf Hachmann und "Germanische Studien"
written by Juergen Udolph?

Especially Udolph has serious objections against a Scandinavian
origin
of the Germanic tribes. He wrote that the oldest place- and rives
of the Germanic can be found in Central Germany, the region Hannover-
Magdeburg and Westfahlen (with east of the Netherlands). Scandinavia
has more recently formed names.

And a Scandinavian origin of the Goths and Vandals is a disputed
matter. For example Wibold Mazczak wrote that the Goths came from
the south of the ancient DDR, went to Bavaria and Austria and arrived
in the Ukraine via Hungary. The Gudones mentioned by Tacitus were
the Baltic tribe of Galindoi.

And what about the origin of the Angli and Saxones? Did the Angli
come from the Angerland in Sweden and were the Saxons Scandinavians
too? And who do live in Jutland and north Germany before the
arrival of the Germanics?
