History of East London & Essex , and East of London.
This map shows the rough boundaries of a London Parish in 1900
I am extremely grateful to David Hale for allowing me to link to his maps at the MAPCO site , a fantastic resource which is now back online again.
Here is the Scottish nls site (national library of Scotland) - There are over 86,000 maps as high-resolution, colour, zoomable images. The maps date between 1560 and 1961 and relate primarily to Scotland, but also maps of England and Great Britain, Ireland, and Belgium.
1800 - East Ham & West Ham 1800 Map from Silvertown – a neighbourhood, by Arthur Philip Crouch 1900.
For maps of Essex, I have only found one decent site - see the Foxearth site maps ; I always welcome feedback if you know otherwise.
