Annie,
I reckon James COURT is very likely the lad (see my Post #333) buried at Spicers Creek (between Wellington and Gulgong) in 1916?
And, as I think I said earlier, people weren't overly sentimental about where they would live out their eternal days. Second husband James's grave might have been not of the calibre that Harriet wanted - or perhaps no extra space, or not where she had lived for many years, or not where she wanted to lie, etc etc. Whereas William's grave might have had room, she might have paid for it, it might have been where she lived, and it might have been in the classy part of the cemetery (don't knock it - I recall my late in-laws taking us to see the plot they'd bought - best view in the cemetery they said - hmmm, thought I - this will really matter to them?).
