That's right, mathprof; debutantes are a legitimate part of social history. We should not erase them, otherwise we shouldn't have clues about suffragettes, for example, just because they aren't with us today. I accept that they may be overused, but that's true of many crossword devices (initially, starts to etc.).
Another extraordinary (as it seems now) example of the English class system was the annual first class cricket match, Gentlemen v Players. When playing for their counties the
gentlemen amateurs were listed on the scorecard with their initials and possibly used a different dressing room than the 'players' who were paid professionals and had just their surname on the scorecards and in newspaper reports. The last such match was in 1962 - the Gentlemen's last victory was in 1953. I still remember many of the amateur initials: P B H May, M C Cowdrey, E R Dexter, M J K Smith, G O Allen, D C S Compton. There was quite a furore when Len Hutton (you see, I don't know his full initials) became, I think, the first professional captain of the England team.
