"""Belville continued to ply her trade up to the age of 86, including making the twelve-mile journey on foot to Greenwich."""

I don't know where these people lived, but twelve miles from Greenwich in the least out-of-the-way direction is Castelnau. Not as bad as I thought (Hunslow), but its still strange to set up your business so far way. Then again, so many people commute from as far as Brighton nowadays. These guys must have been early adopters.
