The youngest son born to Annabel Orong resulting from a liaison between Mr. Wright and Annabel may have signed the post card. His name was Wilbur. Annabel lived in Bogner Regis where she met Mr. Wright while he was on holiday at a Butlings Camp. However the younger Wilbur Wright should have properly signed the card Wilbur Wright–Orong.
