Based solely on births and marriages recorded in Northumberland in the 1993 LDS IGI, here is my analysis of which Northumberland parishes contained Wanless families (any spelling) from 1583 to about 1830. I divided the time period into chunks which seemed to reflect the migration of the families; i.e. the 2nd chunk starts at 1654 because that's when I first started seeing births/marriages outside of Morpeth & the other "first tier" parishes. Sorry if this is hard to read; I had to sacrifice some legibility for file size. If you download the image, you may be able to zoom in with some other tool.

The way this works: Look first at the yellow areas only - these are the parishes in which Wanless records were first recorded in the IGI. (The earliest locations were Morpeth, the city center of Newcastle, and Hexham.) Then look at the pink areas - these are the next set of parishes into which Wanlesses expanded. Then light blue. And so forth.
