History of Wigan   (Help with ancient and recent history.)

Thanks for the leads. I now have some research and reading activities to do this weekend. One thing more I recall from Mum's old map was that it was set up as a Street Directory, with a grid overlay and all the streets of the day either on each side of the map or on the reverse side. Made it very easy to look up a street. Wish I could remember more about it, particularly what the heck we did with it!
