Hi all,
Please move if not in the right place! At the time of the 1871 census, my ancestors lived at 8 Westgate Street, Southampton. Much of the original street is gone, it's now a more open space, and the current number 8 is seen below. I think possibly it's the smaller door to the left?

Anyway, I'd like to know whether number 8 kept its place since the 1870s, or whether the current number 8 is a new number 8. If you see what I mean.
Here's an old photo of Westgate St, before the old buildings on the left were removed:

I wonder if number 8 has always been number 8, or if my ancestors' number 8 was on the left.
Did they have street maps with house numbers on back in the 1870s? If so, does anybody know where I could access these? I notice some sites offer old maps but at a cost. I'd be interested to know if my ancestors lived in one of the remaining buildings. I don't know where to start!
