I know of Continental practice - the Scottish use was a curiosity I'd never really taken time to consider before - and thank you for your concise replies!
One further aspect is that I think there was always a certain competiton between Mary and her cousin Elizabeth - and Elizabeth spent her years in imprisonment at Hatfield doing what would these days be at least a Doctorate in Latin poetry of the Classical period, with the result that English pronunciation is utterly unique, putatively a throwback to the days of Cicero, and giving a hint at an earlier roughness - the rest of Europe uses a Hispano-Italian elision and nasality. The Arabists are even more interesting.
