I think the heavy Scandivegian influence on Geordie/north eastern English is because of the heavy settling of the area that happened during the viking/Danelaw years. Iirc?
I'm sure that Vometia can offer a local insight but yes, the North's culture was heavily influenced by the Dane invasions and settlement, much more than the South. I live almost on the Danelaw border and it is interesting to see how the place names change.
