Like Sandra, Alexandra - they'd be pronounced with a 'sand' sound up north, but a 'sarrnd' sound down south. Not just a subtle difference in emphasis - a black and white divide.
I've spent the last month straining my brain in disbelief that I can't think of a single other example for girls (I've come up with Grant/ 'Grarrnt' for boys). My husband claims there's no other examples (exarrmples!) - surely this can't be?!
Help me prove him wrong Mumsnet?!
