One should be careful to not confuse informal locality names, with parishes
and other formal hierarchy.
Informal locality names are great, and we should have them, but it would be
a mistake to assume they can be added to a hierachial structure: many
informal districts cross formal boundaries, for one thing.

(Urban parishes, in Greater London and and the rest of the country, were
moribund well before 1965, with a 1:1 mapping of parish to borough
anyway.  As an example, the parish of Cranford was abolished in 1935, going
to form part of the parish of "Heston and Isleworth", which was contigous
with the urban district of the same).
