Pub names

Pub names are presumably used to identify and differentiate each pub in order to aid pissed folk find their way to and from them. Modern names of course are often a cynical marketing ploy, or an attempt to create brand awareness, frequently using a comic theme thought to be memorable. Hence The Slug and Lettuce, Filthy McNasties and even Wetherspoons. Then there are the pub names which reflect local trades or businesses such as The Masons Arms, The Black Bull and The Coach and Horses.
Until quite recently I had associated the name The Royal Oak with either the King’s Navy of old or some ancient oak tree in a churchyard in Kent or Buckinghamshire. I stand corrected for this Royal Oak stands in the landlocked town of Keith in Morayshire where in addition to there being a dearth of high seas and battleships, there is in fact a severe lack of English oak trees.
No matter! A pint in said Royal Oak would solve the riddle I thought.
The landlord would have some daring do story to tell about piracy on the high seas or some local bank clerk made good as captain of HMS Illustrious or similar, dealing out justice and retribution on those who dared to challenge the might of the British Empire.
Sadly the place is closed so I will have to ask at The Seafarers Arms just down the road.
