This letter was found by chance while I was searching for information about the original Cape Schanck homestead, and past experience has taught me that it is far easier to take a side track from any current research to record such discoveries than to rediscover the source later on.

It is in the last paragraph of the letter that the confusion is revealed. Both "Moreland" and "La Rose" were in the parish of Jika Jika. To access the parish map, paste the following into your search bar.

The last paragraph of the letter follows.
"Some time in the forties - or, indeed, it
may have been in the latter thirties (for
Dr. McCrae first arrived in Melbourne in
1838) - he built a house called 'La Rose' on
a property of his which he named 'More-
land' (and known as such to this day), after
one of the estates of his grandfather in
Jamaica."

MORELANDconsisted of crown portions 133 and 126, containing 323 and 316 acres between the Moonee Ponds Creek and Sydney Road, extending, respectively, 2000 links (400 metres) north and south of today's Moreland Road. Michael Loeman, later a pioneer of Bulla, managed and then leased "Moreland" for about 14 years before purchasing "Glenloeman" on Loemans Rd which straddled the boundary of the parishes of Bulla and Tullamarine between Deep Creek and Jacksons Creek. (VICTORIA AND ITS METROPOLIS: PAST AND PRESENT, 1888.)The Moreland Road bridge over the Moonee Ponds Creek linking the parishes of Doutta Galla and Jika Jika was named the Loeman Bridge to honour Michael's early association with the estate.

LA ROSEwas portion 141 of 270 acres and being elevated presented a far superior site for a homestead with views in mind. Farquhar McCrae purchased the grant and had built what is believed to be the core of what is now called WENTWORTH HOUSE before he dudded John Fitzgerald Leslie (Alphabetical) Foster regarding the transfer of the Eumemmering Run near Dandenong (in which town streets are named after both), was horse whipped by Foster and fled for his life to Sydney where he obtained a prominent position at its hospital. The extant bluestone mansion was completed by Coiler Robertson.

Statement of Significance

What is significant?
Wentworth House at Pascoe Vale, known as La Rose during the nineteenth century, was built from c1842 for Dr Farquhar McCrae. He was the brother-in-law of Georgiana McCrae, who made several references to Farquhar and La Rose in her diaries. Farquhar had migrated from Scotland in 1839 with his mother, wife, sisters and children, and moved to La Rose in 1842. He was from the Scottish gentry, and was immediately successful in the colony, becoming a magistrate and the director of several companies and a bank, and was prominent in early colonial society. He got into financial difficulties during the depression of the early 1840s, and in about 1845 moved to Sydney, where he practised medicine. During this time the property was leased and farmed by Coiler Robertson, who purchased it in 1852, after McCrae's death. It passed in the mid 1850s to James Robertson (probably Coiler's son*), a partner with Robert and Peter McCracken in one of Melbourne's most successful brewery companies. The property of more than a hundred hectares remained intact until 1899, after which it was progressively subdivided, after 1920 by the War Service Homes Commissioner. The house is now on about an acre. It was renamed Wentworth House between 1908 and 1911. etc.

(*James, described as a brewer aged 17 upon arrival, who was probably instrumental in the early success of the McCracken brewery, was indeed Coiler's son and the brother of Peter McCracken's wife. He is not to be confused with James Robertson Snr and Jnr of Upper Keilor and Aberfeldie (also related to Peter McCracken as J.R. Jnr's daughter married Peter's son, Coiler) or James Robertson of "Gowrie Park", now the suburb north of Hadfield.)

N.B. The source of the horse whipping of Farquhar McCrae by Alphabetical Foster cannot be found on trove and may have been in Sam Merrifield's Annals of Essendon or a history of early Victoria such as Bearbrass. However, while looking for it I discovered an article which gave detail about Andrew and Farquhar McCrae's brother, Alexander (obviously Thomasann Blackburn's ancestor, Captain McCrae*) who also settled in Melbourne, although I have seen no previous mention of him.
