I want to draw your attention to this evidence which makes it clear that the DCR child
IS the correct Bridget GRAY. That is, the one you are seeking information on.
Elizabeth BARRETT you will recall was the woman fostering Bridget GREY of the DCR.
This item looks at the court case regarding Gordon Charles A. McWILIAMS (Bridget's husband) in the carnal knowledge of a girl named Daphne Mary REIDY aged 13 years and 11 months.
She lives with Mrs Elizabeth BARRETT of Crows Nest. So was another foster child of hers.

Daphne is described as “a relation of the accused man’s wife”
Another item about the same matter.
https://trove.nla.gov.au/newspaper/article/223500505?searchTerm=%22gordon%20mcwilliams%22There is a boy named in the first article. His name is Barry
ROSS. You will need to read it carefully with an open mind, but it leaves no doubt.
It means also that you now have the name of Bridget's father.
