You know Karen, I was just thinking earlier about John McINNES.
I know there is no (obvious) registration for his death on the NSW index, but I do wonder if he died about the time of birth of Ernest Nerney ??
Something "catastrophic" has obviously happened to this family in 1877.
Do you have a date for Ernest Nerney's birth?
It doesn't matter too much if you haven't. But somewhere in the space of say, seven months, in 1877, this family (or part of it) has moved from Balranald (Ernest's birth reg'd. there) ... to Sydney (800 odd kms away) !
There doesn't appear to be a historic society specifically covering Balranald, but the Balranald Shire Council may be able to assist with cemetery records ? May be worth trying there to see if there is a record for John McINNES ?
[Gosh ... Balranald was a wee place - 1873 population was only about 350.
