Thank you Mum mum for your reply, I'm sorry for the delay in getting back to you, but I have spent most of the weekend in bed with a cold.
You are correct of course she probably would not have been buried as a Pinch unless the divorce actually went through. Other than Pinch or Passini as a surname I would be guessing. I have not found a 2nd marriage for her under the name of Pinch or Passini and several variants thereof, but of course this does not stop her simply living with someone.
Amelia married at Bealiba, and I had been unable to find mention of the wedding or Amelia's death notice on Trove either. PROV has a digitised copy of Amelia's will but unfortunately it was of no help as it was an application for probate on behalf of her husband as she died intestate.
Again thank you for your time in replying
