If you were to talk about where Pelham Crescent is in London, what district name would you use? Kensington? South Kensington? Is it close enough to count as part of Knightsbridge? (Not according to Wikipedia, but.) Or something else entirely?
It’s a beast, trying to sort out the boundaries of intra-urban place-names for a city you don’t live in. And for all I know the areas were defined a little differently in 1884, but that officially falls into category of “if you can prove me wrong, Dear Reader, then you bloody well deserve your victory.”
