Recent Field Report: Free Worlds League 2765 refers to the ruler of the Duchy of Andurien in 2765 as a 'President'. As far as I know, it makes it the only source that does that, since every single other Humphreys ruler of Andurien worlds holds the title of 'Duke', as do both the previous known ruler of Andurien (Duke Martin Humphreys, c. 2729) and the next known ruler (Jonathan Humphreys, c. 2821).
Is this simply a mistake and 'President' Radford Humphreys should be Duke Radford Humphreys or does it imply that the Humphreys family were temporarily stripped of their title for the support of Oliver and Boris Marik?
