Johns obit doesn't give anything up. Pretty much says he had been in the Towers for 23 years but nothing on where he was before then.
1895
ANOTHER old resident of Charters Towers, Mr John Romberg, passed away on Sunday afternoon. He came to this field about 23 years ago, and after following mining with indifferent success, g ot into the Day Dawn p.c. just before that famous mine struck it rich. When the mine was sold to British capitalists, Mr Romberg invested his share of the proceeds in town property, of which he held a great deal,including the Royal Hotel. For some time past Mr Romberg, who was over 70 years of age, had been very feeble, and an affection of the throat carried him off at last. Mr Romberg was of a very retired disposition, and took no part in public affairs. He leaves a widow and grown-up family.
