Some other info from archeological finds in modern Kaliningrad:

Authors (Polish, Lithuanian and Russian) research viking age finds in modern Kaliningrad, ancient Prussia and finds out Norse warriors among local people. Norse chieftains graves. Large cemetery near Truso. And other finds. Among conclusions is also this note:
"It was within the limits of this interethnic (
Balts, Varangians - my comment) contacts route where Grand Duchy of Litowsky came into being, probably as an instrument of control over its (
Neman trade route - my comment) uninterrupted activity".
Everything starts to make sense. Piece by piece.
Some new questions still do arise.
1) Scandinavian colonies are attested in Prussia coastal areas (Truso, Kaup and some others, vikings from modern Sweden territory). And then we have Yatwings deeper inland. There are several touchpoints but for my theory to hold we need both sources to be in majority one clan. Can the Baltic ones (Yatwings + Truso colonists) be the same folk? Could it be there were two gangs/clans operating and later conflicting - Rurik's men and alikes (L550, L1025-) on Kiev/Novgorod trade route and Yatwigr's (?) men (L550, L1025+, possibly M2783+) on Neman trade route?
What started as simple speculation, turned into google searches. I still dont give 100% credibility to this idea, but at least I have learned a lot on Varyag Balt early interactions :)
