BIO
A player named Hallack did appear in at least one match for Norwood, against Melbourne on 23 August, 1884, at Adelaide Oval.
It may have been Edward Headley Hallack, who was born in 1846 and in his obituary in The Advertiser (16 May 1916 p6) was referred to as "a well-known Norwood footballer"
This would have had him aged 38 for the game against Melbourne in 1884.
