The MD of my employer's sister-company was just telling an interesting story.

Apparently an ancestor of his once killed the Prince of Wales ('a Prince of Wales' if you prefer, although I suspect the correct form is to use the definite article even if you're not talking about the incumbent) with a cricket ball. Intrigued, I asked which, planning a trip to Wikipedia, and sure enough there is a legend that Frederick, Prince of Wales was killed with a cricket ball.

The claim that he died after a blow to the head with a cricket ball is described as apocryphal (it's not clear which part is disputed), but that needs a citation. Well, as it turns out, Downstairs' MD has the citation: he'd found a reference in Cox's 'The Pelhams' (detail pending, although he says Cox was a contemporary and I think I've established she was called Marjorie) saying (as best he remembers) that
"[Frederick] died from an impostume on the chest, caused by being struck earlier by a cricket ball."
I might have a go at verifying that to fix the paragraph in Wikipedia (especially if the research can be done entirely online ;-).
