Hi,
I stumbled across similar questions when I was looking at Census forms for my family in Wouldham, Kent. And what I found is that rather than the households being split up per road. Each individual group of Terraced houses would have been given their own name. If you look at my first attachment. What is now called 'High Street' wouldn't have been recorded with the normal house number system we use now. Instead each little group of houses you see would have their own name, for example Portland Terrace, Heartfield Terrace, etc.
Then I believe that each house that is in that terrace would have been referred to as a cottage.
So for example, My family were listed as having the address, 'Langford Cottages'. The Census form showed 8 different families living in 'Langford Cottages'. Today there still exists a group of 8 Terraced houses in Wouldham Highstreet with an old plaque on the building facade that says 'Langford Terrace 1807'. So these will most definitely be the 8 Langford cottages that the 8 different families lived in.
Please see my second attachment which shows this. If you go onto google street view you may be lucky enough to find some plaques that still exisit on the fronts of some of the houses.
hope this helps.
Thanks, Shaun
