Is this Castro, Orton or Tichborne??

Another fascinating piece of Wagga Wagga history is the case of Thomas Castro who was a butcher in the town who claimed in 1866 that he was in fact Sir Roger Tichborne (who was heir to his families fortune, and presumed dead at sea). However the man known in Wagga Wagga as Thomas Castro is actually thought to have been Arthur Orton, presumably trying to get his hands on the Tichborne fortune by deceit. The whole episode fascinated & shocked Victorian society during the 1860's and 1870's. Who is actually the man in the photo...is it Castro, Orton or Tichborne?
By the way, are you a fan of my photo?
