Thank you everyone for all your input, we all had a good chat about it last night after closing and scouted round the pub to see where the old entrances have been bricked over, and dug out an old photo of Oxford Street that was hanging on the wall in the corner. Quite spooky, especially after a few drinks!
Also, maybe my sums are wrong, but how can Dafyyd Lewis have been born in 1861, buried 1926 and died at the age of 71? Surely he must have died at 65?
