Hi all,
I've been reading this thread 'word-for-word' - as I've come to the Graves/Hand family through Marianne Hand who married James Messenger [4th great grandparents].
What a great job you've all done!

Nowhere in the family story was the surname for James M.'s wife [only Mary Anne], and I believe "by George, you've got it"!

The little research I'd found on Thomas 'Henry' Graves in Australia, on Trove, found much of the same information about his finances - and being such a public and prominent figure during the remainder of his lifetime.
The buildings that he owned, his estate, was held in trust for 20yrs, and 'disposed of by auction'. The properties that were sold included; the United Service Hotel [King William St], and buildings at the corner of Waymouth-street and Light-square.
I haven't been able to source any further information of Messenger family members [nieces or nephews] being bequeathed in any way, to Thomas' fortune.
The search continues.
Thanks again,
Meg
