Vikings tended to go for higher ground, even hilltops, and I would have thought the often marshy nature of that bit of Wirral would hold few attractions for them. There would not even have been a particularly easy access to the sea from there (albeit that coast lines will have changed a lot).
Another point is that a Google etc does not turn up many places/ roads called Danger Lane. If the "invaders", Viking or otherwise, were a derivation then I would have expected a few more. If we discount the Austrailan and US Danger Lanes then the main hits are really all for Moreton.
I could do with some old maps of the area - there are some on the web eg tithe maps, but they do not show anything special other than a few ponds.
Just confused and inquisitive. Old census records say I had relatives living there.
