"Restgermanen" in Early Medieval Poland

Two publications about Restgermanen (Goths, Vandals, etc.) in Early Medieval Poland:

Attachment 89629 - "Germanie na ziemiach Polski w zaraniu średniowiecza"
(this one was written by user Bazyli from historycy.org and originally posted there)

And "Goci Gniazdowi" - https://www.magnapolonia.org/wp-cont..._gniazdowi.pdf

Mind telling the gist? Where were those pockets of Germans, how long did they survive, what role did they play?
