What do the following have in common?
To keep the game interesting, please do not post an explicit answer. Instead, give another example.
(And yes, Googling is allowed.)
Cecil B. DeMille
Update I thought this might be too easy – with “Percy Weasley” as the giveaway – but it seems instead to be too hard.
Someone asked for a hint. The commonality can be stated in a single sentence, and will be obvious once perceived.
First hint: Syntactic, not semantic.
Second hint: Andy Sabl and James Wimberley have an unfair advantage.
Second update Answer below the fold.
“People whose given names are the names of English or Scotch noble families.” Dominic Murphy got it; I restricted my examples to families ennobled before the Revolution of 1688, but that wouldn’t have been obvious. Toby provides four more excellent examples. And yes, “Ashley Montagu” deserves extra credit.
It strikes me as remarkable that so many common English given names originate in aristocratic surnames; I have always found Jewish “Sidneys” and “Mortimers” and “Stuarts” faintly amusing.
Thanks for playing! Hope the game didn’t prove too annoying.
