Thanks again. I understand and agree with everything you say (I think). There is still work to be done, but there is still hope.
Would you believe it, I hadn't twigged to that. I find that old florid writing style quite difficult (Charlotte Bond/Clark's final address looked like Dellurska or Detturska St to me, but it later proved to be De Murska St!), so I just assumed that was a floridly written McQu rather than McW. Silly me! Not that it matters of course, but I should have picked it.You would have noticed that Ernest HARGRAVES on his marriage cert noted his mother down as Mary McWilliam.
This really is a convincing point. I had been unable to find Mary on the Ancestry lists - perhaps because I didn't try Hargrave, I can't remember - but it certainly is a useful missing piece of the jigsaw. Both lived in E melbourne also, or ended up in E Melbourne Hospital, so that is consistent. Clearly now I need to get either her or Fras's death certificate and verify. I had put off this until I had better info, but I think this is it! Thanks heaps!A death in Victoria...but seen here as Mary HARGRAVE...The age at death seems appropriate.

PS I searched for Hargraves in cemeteries around Melbourne (as many as I could get online) and found a heap of Hargraves in the Lilydale area (where Mable died), including a Mabel Grey in Lilydale cemetery. Different spelling, but pretty likely, I would think. Haven't found Francis or Mary, but will try spelling variations.
