There's an oratory, a cemetery and a road all called Brompton, but I've
never heard anyone refer to an area called Brompton, and I've lived in
south London for over 50 years.

These days Brompton is more usually called "South Kensington", but
Brompton is a far older name, dating back to at least the 13th century.
