On the subject of Chiswick map errors, several different companies' maps
show the northern end of Great Chertsey Road as "Alexandra Avenue". Is this
an old name, or a deliberate error?

It's the original name of the road built in 1923 from Burlington Lane
down to the Thames. After this was extended to become the Great Chertsey
Road in the 1930s, only the short stretch alongside Chiswick Community
School retained the name Alexandra Avenue, and even that has now dropped
out of use, although the estate on the opposite side of the road is
still known as the Alexandra estate.
