I noticed on Barbara Windsor's 'Who do you think you are' that the expert was able to look up an address and find out what kind of people lived in the area. Does anyone know whether those records are kept for all areas or just London. My grandfather lived in George Street, Chelmsford at the beginning of the 20th century. His father was a labourer possibly on the railways and I am wondering what kind of house that was (it's no longer there) and what the living conditions were. Many thanks. Kate
