One may think that this is one of the easiest qualifications to determine - what could be easier - find an A-Z and anyone who lived inside the Trafford boundaries are in and those outside the boundaries are not - simple.
However, like just about everything else connected to this research, one has to have an open mind and be prepared for the unexpected.
Boundaries are constantly changing and there were some quite drastic changes in the late 1800's - early 1900's. I shall deal with the boundary changes within each area as they affected that area.
Apart from boundary changes, people who lived just outside the various towns, villages and hamlets, may have been employed within, or practiced a sport within. Again, it is not an exact science.
