There is such a trove on Trove! By way of background, see More tales from my mother 3 — Braefield NSW 1916-1923, Jean Christison to her grandmother — an undated letter from Braefield, More tales from my mother 4 — Dunolly NSW — and conclusions. Roy Christison was Head at Milton, his next school, from 1925 to 1929. Then Shellharbour 1930.
I am not sure but think this is probably Braefield
And here is Harry Hamilton.
Moving forward to 1926 I find my mother writing in the children’s section of The Sydney Mail, something she continued to do through the 1920s. (A fellow scribe there was one Judith Wright!)
I see my uncle Neil is now with the family – and referred to as Neil, not Nelson.
