Difficult to say without going through all of them.
Checking those donated from Great Britain, there were some that certainly came from cities/towns and so on.
If I had been an expert on smaller villages and the like in UK, I would have been in a much better position to evaluate all the names for you, but sorry, I am not
Also the aircraft itself C2926 is not listed as a presentation aircraft!
Although social background was (and still is) important if you wanted to be an officer, RFC and later RAF needed far more pilots than the upper classes could produce. I have not studied the subject, but surely there must have been a large number from, should we say, the working classes who became pilots?
