Maps are a very useful source for genealogists. They show the relationship between different parishes and counties. I have tried to choose the areas where most of the Yeos and Yeas were in the 1700's. Click on the headings above.

It is not easy to scan maps so they can be read over the internet, so I apologise if they are a little blurred.

With the map of distribution I suggest you save it and then import it into word and enlarge it.
