The 1910 House Map was lent by Anna Blomfield. Thank you, Anna!
The map is a copy made (probably) with old blueprint-copying technology. The original was hand-drawn, presumably in 1910. The copy then had some additions made in black ink and white paint. The version shown below has been heavily photoshopped to improve the contrast and make it more readable.
Why the map was made is a complete mystery. Any ideas? Leave a comment below! Also, what is the significance of the additions and subtractions? And the Xs in some houses?
This is a splendid resource, because it allows us to match up house locations with the 1911 census forms. Click for a bigger version.
