Constable ERASMUS MAWBEY TREWINNARD appointed inspector of slaughterhouses, and cattle intended for slaughter, for police district of Kyneton.
This was also announced in the Victorian Police Gazette of the same date.
In the 20 October 1864 issue, it had been announced he had been appointed as a constable, number 2012.
He appears to have been born in 1844 in Surrey, England and was living there at the time of the 1851 and 1861 censuses.
At the time of the latter, he was living in Bermondsey, London.
He appears to have married Mary Hill in 1895 and died on 2 February 1897 with probate granted in Melbourne, Victoria on 26 March that year.
His wife died in 1903 at Cormella, Victoria.

His name suggests he was the son of a female Mawbey who married a Trewinnard.
'Trewinnard' is a Cornish name and a woman bearing it in the medieval era was one of the few British female pirates.
I have not been able to find any record of how and when he arrived in Australia.
