I have previously commented on the range of names by which I have been addressed in correspondence: ‘Mr Louth’, ‘Mr LNO Louth’, ‘Professor Norton of Louth’, ‘Mr Lord Norton of Louth’, ‘Lord Louth’ and so on. Some of the salutations in letters have also been interesting. It is not unusual for a letter to open with ‘Dear Lord’. However, one I received this week was a first. It opened with ‘Dear Baron Philip’.
