Well, Guessed...as I went to a school (Handsworth in Brum)which had the Staffordshire knot on its badge (border changes), I had many classmates from "over the border" and I used to be able not only to do both dialects but place people within the different areas (I could tell Walsall from Dudley from Wolverhampton for example). I'm no Professor Higgins and couldn't do it now, but still do the odd Aynuck and Ayli story. I doubt there's more than six of us on the Mudcat who'd know the difference!
Herself is Bucks born and bred but her mother came from Coventry (of Scottish stock), her father was born in Birmingham and his father in Wolverhampton! Me? Born in Nechells of Birmingham parents on both sides, variously of Irish & Cheshire descent way back & brought up in Nechells and Erdington till I went to college.
