Oswaldtwistle in Lancashire is called Ozzle by its inhabitants, I believe.

Tho, as to these odd OK pronunciations, you can't be sure how they go timewise. I was brought up that, until recently, Daventry was pronounced "Daintry" by the posh. But then read somewhere that this was a C16 misapprehension that it was founded on the site of a great tree planted by the Vikings [Danes], whence "Dane-tree", and that up to then it was pronounced as spelt, as it is now. Who knows the truth of such matters? ~~ e.g as to the personal name, some Featherstonhaughs pronounce themselves as spelt, some Fanshawe, some Feather-stonnach &c.
