Aye. I may be wrong but I thought 'wick' meant 'creek' and 'viking' (Germanic V pronunciation of W' meant 'son of the creek'.Because Old Norse and Anglo-Saxon have the same origins it's probably quite difficult to pick apart.
One thing @tiptoad does mention often though is that if you look at placenames - the traditional Norse place suffix of '-by' basically stops at the Tees, which suggests they never really settled or had much influence North of it. So probably didn't have that much influence on our dialect.
Certainly, most Norse loan words we use are common to all modern English speakers - skirt etc'.
There are place names with wick or wich all over the U.K., from as far south as Greenwich and Harwich up through Southwick, Alnwick, Hawick all the way north to ... err ... Wick!
