May I speculate please...
At the NSW SRO online Index for Squatters and Graziers there's :
1845,
J. Jenner with TWO stations, both in the Bathurst - Wellington district .... both associated with a William Henry Wright. These properties named as Wolandra and Gogodneygeery. There is NO copy service associated with that index at present, so someone would need to attend the SRO to view and copytranscribe that part of their film. Perhaps J Jenner was managing the properties for William Henry Wright, however, the contents of that file should provide those answers.
So then I looked at the NSW SRO index for LAND I found mention of a William Henry WRIGHT as a Lieutenant, 1838-9.
Next I found a William Henry WRIGHT's appointment as a Magistrate and the Commissioner for Lands in the Wellington district

This is all speculative on my part, and somewhat tenuous at the moment, and may well have no bearing on your Susan Jenner. The NSW SRO index info is simply a possible clue to be followed up once you have validated your research for her.
