'Near Tunbridge Waters' is hardly any jump from 'Near to Bridgwater' as you've guessed. Just going to check if I have all the versions you've posted and whether they add anything to the reconstruction.

I certainly haven't seen the Peter Parley extract. I have some original Peter Parley booklets in the loft if I haven't already sent them to the charity shop. That was a cracking find, Richie.
