Heywood - I just love that photo from 1905, showing the man in the flat cap pushing his bike - the houses have hardly changed from the Google picture of today. Thanks for that extra!
I think you have hit the nail on the head with the maps. Looking at the 1880 it clearly shows the street, although yet to be named. It also shows that the houses are yet to be built.
Strange though as I did find in an old newspaper a piece where someone is asking for permission to alter the houses there in 1882.
Can I copy the bit of the newspaper here so people can see it?
