Another puzzling news article from 1857 (states to be from the Goulburn papers):
TOUCHING INCIDENT.-A poor woman named Ralston, was committed to gaol a short time ago, as being of unsound mind. She was suckling an infant, and it was deemed imprudent that Bhe should take her baby with her into prison. The child passed into the care of a person known as the Gipsy Queen. There is now temporarily residing, at a cottage on the new line, a person named Murphy, whose wife has also an infant at the breast.
Mrs. Murphy was sitting on the door step, on Monday evening, when the Gipsy Queen carne up with Mrs Ralston's baby. The Gipsy stated the melancholy history of the unfortunate baby she was nurturing, and asked Mrs. M. to give the " poor little thing a wee drop from the breast." No'sooner had kind hearted Mrs. Murphy taken the infant in her arms than the Gipsy vanished. Murphy, on his return home, was highly indignant at this "little addition to his family" being forced upon him, and yesterday applied to the Bench of Magistrates for redress of this " crying" grievance. His demeanour was so excited that he was ordered into custody, but he was released on the rising of the Court.
Of course Catherine was with John Walter by 1857, but Joseph Walters was born 1858 in Binalong, a bit further along the road from Goulburn.
