Researchers beware! Many squatters mentioned in correspondence to the Governor in early days and described as being in the WESTERNPORT DISTRICT were nowhere near the Mornington Peninsula or Gippsland areas. Just some examples are: John Aitken (Mt Aitken) and Edward Page (Glencoe) near Sunbury, Edward Dryden near Hanging Rock, Peter Young of the Sugar Loaf Run (which had to be near Seymour) and other runs called Cairn Curran, Kilmore etc.

Harry Huntington Peck knew just about every square inch of the eastern states as he demonstrated in MEMOIRS OF A STOCKMAN which is available online. Here's an example of the confusion caused by the description of squatting runs nowhere near the eastern port (that was the westernmost one when discovered) having their locations described as WESTERNPORT.

Leases were recorded in Sydney Government files as in
Westernport and held by Cuthbert and Gardiner called
Moonee Moonee Ponds and Two Rivers, the latter bracketed with
Westaway. But it is extraordinary that the oldest residents of the
locality never heard of such runs. Neither did Mr. Angus McNabb
of Wendoora, originally part of Westaway, whose grandfather
Archibald McNabb was manager for Cuthbert, after his partner
Gardiner went to New Zealand. He could not find any trace or
record of them. It is a coincidence that the name Moonee Moonee
Ponds is so like that of the suburb of Moonee Ponds close to
Newmarket?as to the origin of which there are also doubts and
arguments. It makes one wonder how it is that both are more or
less a mystery. (P.165, MEMOIRS OF A STOCKMAN.)
