That Viking culture became a part of life in Northern England is evident from the language, the names of towns ending in Viking suffixes like –thwaite or –by, as in Whitby, but also in the history and lore of the people. This is well documented and presented in the Yorvik Viking museum in the northern city of York in England. I have linked below the Jorvik web site.
