From the Telegraph of 28 May 2016: ARTHUR His Honour Judge Sir Gavyn Arthur, died suddenly on Monday 16th May 2016 aged 64 years. Deeply mourned by his Godchildren and his many friends. A private funeral has taken place. Details of a memorial service in London to follow. Donations if desired to The British Red Cross, care of Chelsea Funeral Directors, 91 Rochester Row, Westminster.
He was hp to Sir Benjamin Nathan ARTHUR 7th & present Bt (b 1979, unm). His death means the new heir to the baronetcy is uncertain. It's either the male descendant of Sir Gavyn's uncle, Archibald John ARTHUR (b 1909, last heard of in 1951) - if such a person exists, or Robert Leonard Sigismund ARTHUR (b 1955, m with four sons). The fact that the present Baronet is not recognised as such, having failed to make good his claim and appear on The Official Roll of the Baronetage (where the title is shown as 'vacant), perhaps suggests there will be little interest in establishing who the new hp is.
