Wikipedia editors once got in a mess trying to say
where Euston is - "Camden" may be the borough name but everyone
thinks of Camden Town, "St Pancras" is an old village name that
everyone now uses for just the railway station, "Bloomsbury" clearly
stops at the other side of the road and "Euston" is what a lot of
people call the area but not much use here given what they've taken
the name from!

Isn't it in Somers Town?

I noticed recently that before the 1960s, Hampstead Garden Suburb was half
in the Middlesex borough of Finchley and half in the Middlesex borough of
Hendon. None of it was in the London borough of Hampstead, in fact it almost
seemed to end at the Hampstead border.
