The Court Circular yesterday detailing the Garter ceremonies stated that the two pages of honour in attendance were The Hon Guy Tryon and Mr Charles van Cutsem (I think the untitled ones used to be referred to as "Master").
Hon Guy Aylmer George Tryon b 2015 is the son of and heir apparent to his father the 4th Baron Tryon who had also been a Page of Honour (1988-1991) as indeed had been his grandfather the 3rd Baron (1954-56).
Guy Tryon must be a new appointment probably replacing Nicholas Barclay who is now 15. The appointments used to be reported in the London Gazette and more recently as an appendix to the Court Circular but that practice seems to have stopped
