Hi Gerry
Thanks for the posting. I think that I my original query has been answered, as far as it can be.
The puzzle as to why my great grandparents, farming in Radnorshire, should up sticks and move to Pontymister (where no other family connection is known) in mid-1881 to run a pub for 2½ years at most (based upon the places of birth of their two eldest children), and then move back to mid-Wales and farming will remain exactly that - a puzzle.
Regards
Chris
