The first obvious crossing of paths by Bella Mortimer and Charles Dillon in the theatre, seems to be early 1873. Thereafter, she seemed to frequently play opposite or alongside him in numerous productions, often as his 'wife'.
Now, in earlier years, when Charles and Clara sometimes appeared on stage together, newspaper reports often alluded to her as being his wife, but still referred to her by her stage name of Clara Conquest. Interestingly, at no point, in all the numerous newspaper reports of Charles and Bella working together, can I see any that alluded to her being his 'real life' wife, that is, until May 1881, just after he died and then again in July 1881, when a Trust Fund was being set up to assist her. It was only after his death, too, when she appeared in various other productions, that she was often noted as Mrs Charles Dillon (Bella Mortimer) and/or Bella Mortimer (Mrs Charles Dillon).
