Regional accents and even local accents are now almost extinct. It is a shame they cannot be put on a UN Red list. My old English teacher Mr Hester recounted that his professor at Oxford had the ability to quite accurately pinpoint an English accented persons origins (back then) in the 1950`s. Is there a single young person in Devon or Cornwall in 2023 with anything like a traditional accent?. Sadly you would probably be deemed unemployable if you did!
Generally not as common, and generally not as strong (just as these isn't, compared to 100 years ago, or 100 years before that, and so on), but they're about, especially in the smaller, working class communities
I've traced the Hancock side of my family back to Ireland, an ancestor came over to Yorkshire during the War of the Roses, and I traced the line from there down to Devon and Cornwall before coming to America. I've commented on other videos, but want to emphasize again how much I appreciate those who are recording and documenting the languages, accents, folk and cultural practices of the British Isles and Ireland for those of us of the various diaspora to learn/remember who we are, especially these days where it's not popular to be a northwestern European descendant unless you hate yourself, at least here in the USA.
