In terms of who were the financiers of the syndicate of "Watson & Hunter", there is this:
From "Colonial Doctor and his Town" The story began in Scotland In 1838 a
large Pastoral Company trading under the name of two partners, Alex Hunter
and james Watson, was formed to acquire pastoral, agricultural and city
properties in Australia. It was generally financed by a syndicate headed by
the Marquiss of Ailsa, Chief of the Kennedy Clan, his son the Hon.Gilbert
Kennedy, Lady Flora and Lady Adelaide Hastings, Captain Arabin, housekeeper
to the house of Buccleuch,
George Watson, son of Watson of Keilor, a cattle
breeder of Forfarshire, Alex Hunter a partner in the legan firm of Hunter
Blair and Cowan, Major McDouall, Sir C.Doyle and some others. Alex Hunter
did not come to Australia, but his five sons Alexander, James, John, Frank
and William all came. The Hunter brothers won fame for their superb riding,
their vigoroud, unconventional lives and their courage."

Watson...I still struggle except we now see a George Watson coming in, maybe a brother of Hugh's
