Hi, I know a few years have passed since you posted this and I hope you may have your answers since then. I reply in case you have not.
I knew a Scottish couple, Bill and Margaret Paterson who managed (not owned) a pub called the Bunch of Grapes, 2 St Thomas St, London Bridge, SE1 in the late eighties. I knew this couple reasonably well until they left this pub and as far as I knew they were childless. They had a golden labrador dog. The pub is now owned by Youngs brewery but was not at the time.
