The town in Ohio is literally spelled Wooster. I'm not sure what that says about us, but it certainly says something.

That's named for a Revolutionary War general, whose name was Wooster, like 1920s British character Bertie Wooster. There were 169 Wooster families in London in the 1891 UK census. I kind of doubt they all descended from the US, so what this says to me is that some British person filling out a form heard the name "Worcester" and very sensibly wrote Wooster.

Worcester is a corruption of Wigraceaster which is a corruption of Weorgoran Ceaster, so rigidly sticking to an orthodox spelling is ridiculous and it should be reformed. Like Featherstonehaugh turned into Fanshaw.
