My WADEY Ancestry 

Variations on a WADEY!

The commonest alternative spelling is a toss up between WADIE & WADY. But there are a number of other varieties I have come across:

WAD(D)AY
WADD(E)Y
WADDIE
WADDY(E)
WADYE

There appears to be a geographical split to these variations.   WAD(E)Y is much more common in the south of England whereas WADD(E)Y & WAD(D)IE are more likely to be found in the north of England & Scotland.
