A great site for the whole of England is http://maps.familysearch.org.
The site not only helps you to locate a parish, but the dialog box gives Information,
Jurisdictions & Options – which gives the ability for a radius search and lists contiguous parishes. You can print or download the information for future reference. The site is technically still in beta although it has been online for several years. It is being fine-tuned for completion, hopefully in the next year. Please try it out – it is a great tool, especially for locating diocese and probate court information.
