On the old map the fields on the west, north of Gloster Hill are called "Sault Hawgh" I thought this would be some reference again to salt, but when you google about and discover what these words mean, one old French, the other old English, it could be "Valley Rapids" or similar.
We could discuss the place names on that map 'til doomsday.
Haugh or Hawgh = a low-lying often alluvial riverside meadow, or a valley
Sault = A waterfall or rapids.
