Australia, Electoral Roll, 1856
There are entries for Arthur and Stephen Charlwood who seem to have been printers and stationers. My interpretation is that they were owner-occupiers in Lygon Street in the University Division of Melbourne but also owned other properties.
Deaths
On the 27th April 1st. at his residence, Kew, near Melbourne, Victoria, Australia, in the 62nd year of his age, of disease of the heart of many years standing, Mr ARTHUR CHARLWOOD, Bank Street, Melbourne, and late of this city.
Norwich Mercury July 1860
Another report of his death has Bourk Street as his address, his firm as Charlwood and Son, and states that he is late of Orford-hill in this city [Norwich]
Marriage of his son
Married, on the 28th Feb., at Melbourne, Charles Joseph, the youngest son of the late Mr. Arthur Charlwood, formerly of this city [Norwich], to Emily Mary, eldest daughter of Mr. R. Lewis, Melbourne.
Bury and Norwich Post May 1865
A mention in a newspaper in February 1850 suggests that he was still at Orford-hill at that date.
I have found him in the 1841 census, a printer in Norwich with a large family including a son Stephen. I cannot find any subsequent census entry. Putting all of this together he left England 1850/1851.
