As mentioned, I actually "walked" the road. St Johns St.
On ancrusty, on a view of any page (example is a census page)
you will notice that above the page image is eg
1871 England Census for Caroline Louisa Miles
London Kensington Kensington Town District 33
You can actually get to anywhere by changing (dropdown selects), say District 33 to District 34, then view all of the census sheets for District 34 and work your way around the streets, even viewing uninhabitted houses.
You can change any of the elements, try changing Kensington to Bow.
Try it, you will not damage anything.
