On 15 March 1916 at the age of 72, a Thomas McMaster was buried at Macquarie Plains. Johanna McMaster, aged 61, was buried at Macquarie Plains on 30 Aug 1918.
Thomas married Joanna McCalley (McCarty, Macauley, McCauley) and their first child was Thomas William, then Ellen Loiusa born on 26 May 1875 and she died two months later on 21 July 1857. I think there were 10 surviving children.

My grandfather was Hollis Roy, of Gretna, their 6th child.
I think I might have found how my long-lost great-grandfather arrived here!

I'd always heard the story that 'He arrived here as a boy of 12 in the household of a minor Scottish laird: his grandparents died on the voyage out, and he was taken into the household of the laird'.
Well, it seems that he was adopted at around 11 or 12 from the Orphan's School by John Harris, of New Norfolk. Certainly he appeared as a labourer on his marriage certificate, at Clarendon at Gretna, where his first few children were born, before he established his own farm at Gretna.
