Mlle. Henriette Yrois , 24, from 5 Rue des Pyramides Paris, France, boarded the Titanic at Southampton as a second class passenger, her ticket was #248747 (£13). It appears thet she travelled together with the film maker William H. Harbeck (ticket No. 248746). She may have been his mistress, but there may be a more innocent explanation . It woulds appear that they were the couple observed playing cards for much of the journey by Lawrence Beesley.
"In the opposite corner are the young American kinematograph photographer and his young wife, evidently French, very fond of playing patience, which she is doing now, while he sits back in his chair watching the game and interposing from time to time with suggestions. I did not see them again."
Both died in the sinking. Ms Yvois' body, if recovered, was never identified however,when Harbeck's body was recovered he was found holding a purse. The purse was later identified as belonging to Yrois.
