Interesting to see the Chesh-ham/Ches-ham bit. Up here in Kirkham Lancashire, the adjacent village is Wesham: Wesh-um to most but Wess-um to some inhabitants. Or Wizzum. The next village is Greenhalgh - Greenhalsh or Greenhash. But Lytham is always Li-thum, never Light-ham or anything similar.

In a more civilised county there's Alnwick - Annik. But everywhere in England you'll find similar.
