Thanks JM - unlikely to be him. This John Hill was never 'in trade' - before he went broke in his 40s, in his wealthy 20s and 30s he mixed with the likes of pastoralists, colonial 'gentry', bankers, state governors, investors, etc. I wouldn't be surprised if he was distantly connected to Sir John Hill of Hawkestone Park, Shropshire. One tidbit that may help sort him out from the others named 'John Hill' re his time in NSW (c1833-1837) was that he was much involved in the turf, both in NSW and SA, and in 1837 brought with him from NSW to SA a thoroughbred Arabian stallion racehorse, named Rainbow. He was descended from a pure Arabian stallion of the same name imported in 1828 from India to Sydney by Captain H.J. Rous, R.N., on HMS Rainbow, the frigate that was his command at the time. John Hill may have been also connected with Young Rainbow, a mare that had previously been the property of Henry Baily of Parramatta, an avid racehorse owner.
