F. Brown, Metro. Farm
After searching the WW1 Embarkation Rolls, I have not been able to identify any soldier with this name and initial, who had a direct connection to the Werribee Shire or the Metropolitan Farm. I don’t think that "F. Brown" from Werribee served overseas with the Australian Imperial Forces (A.I.F.)
The closest match on the National Archives of Australia web site, for people who applied to enlist in the A.I.F. during the Great War is: Alfred Ernest Brown, age 18 born in Yarraville is listed in the National Archives of Australia web site in their Series No. MT 1486/1. That is a series of individuals who applied to enlist in the Australian Imperial Force, and were either rejected, discharged while still in training, or went on to serve in Australia only. His file has not been released yet.
Referring to the "Roll of Honor" which was published in the Werribee Shire Banner throughout the Great War, the name "Brown, F. from the Metro Farm" first appeared in Werribee Shire Banner, 21 March 1918, p.1 and remained there until Werribee Shire Banner, 13 February 1919, p.3 when it was amended to "Brown, F., Werribee".
The only Brown's living at the Metropolitan Farm in Werribee at that time were Reuben Rudolf William Brown and Violet Brown (nee Savage). They had married at Golden Square in 1911, and moved to the Metropolitan Farm in 1913. Perhaps "Brown, F." was a cousin or uncle?

The [Werribee Shire] Secretary produced a list of names compiled by him, as instructed, of all men who had enlisted from the Shire, or were born of parents residing in the Shire.
