I’ve commented a couple of times on people who in reality spoke with Scottish accents being portrayed on television or in film as speaking with English accents. Judge Lord Mansfield and Sir Arthur Conan Doyle spring immediately to mind. Watching the excellent Hornblower TV series, excellent at least compared to the hamfisted Sharpe series, I would never have guessed that the hero’s mentor and supporter Captain Edward Pellow was a Cornishman. The usually excellent Robert Lindsay gives no hint that Pellow, who really existed before being immoratalised in CS Forester’s naval fiction, had once been an ordinary jack tar and throughout his life had a discernible Cornish accent. I would have thought these facts make the character more interesting.  So, it’s not just Scots who are being written out of history by the acting profession, it’s the working classes too.
