East Street is now in Walworth, SE17, it runs from the Walworth Road right through to The Old Kent Road, making it a very long road. You can also find it listed as Camberwell in some older census returns and other records.
After the war and well into the 1960's there was a lot of demolition of old properties and there are a lot of 60's and 70's estates/flats now, many of which are at the Old Kent Road end, including the Aylesbury Estate. In fact apart from some older flats and a few houses at the Old Kent Road end, there are very few houses left.
Do log on to the website mentioned, it is very good.
